Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-sensitive material for forming a transferred image by utilizing a polymerization-curing reaction which occurs when developing a silver halide. In particular, the present invention relates to a highly sensitive photosensitive material for image transfer which can be drawn by scanning exposure such as laser.

[0002]

A method of forming a polymer image by imagewise exposing a light-sensitive material containing a silver halide, a reducing agent and a polymerizable compound to develop the silver halide, thereby polymerizing the polymerizable compound on the image. However, Japanese Patent Laid-Open Nos. 61-69062 and 61-73145 (US Pat.
676 and European Patent Publication No. 0174634A).
It is described in. In a typical embodiment of this image forming method, an uncured portion of a polymerizable compound containing a colorant is transferred from a photosensitive material to an image receiving material to form an image on the image receiving material. When forming a color image, a light-sensitive material containing two or more types of microcapsules (or packet emulsions) containing different colorants is used.

Although the above-mentioned light-sensitive material has high sensitivity, it destroys the microcapsules to form an image.
The resolution depends on the size of the microcapsule (usually about 10 μm or more). Further, the colorant flows out and diffuses together with the uncured polymerizable compound due to the pressure breakage of the microcapsules, which causes the image to become thick and the resolution to further decrease.

On the other hand, as a means for obtaining an image with high resolution, a light-sensitive material is known in which a release layer is formed on a support and a photopolymerizable layer is formed on the release layer (JP-A-59).
-97140 and 61-188537). In this system, an image is once formed on a release layer on a support, and then this image is transferred together with the release layer on another support. Since the peeling layer is transferred together, the image can be transferred while maintaining high resolution.

However, since this light-sensitive material is a system in which a cured image is formed by a photopolymerization initiator, it has a low photosensitivity (1/1000 or less of the light-sensitive material using silver halide) and is generally UV-sensitive. However, it does not have sufficient sensitivity to a laser light source (generally visible light to infrared light).

[0006]

SUMMARY OF THE INVENTION As described above, in both types, not a photosensitive material for image transfer satisfying both high photosensitivity and high resolution, but a photosensitive material for image transfer satisfying such requirements is realized. Is said to be very difficult. According to the research conducted by the present inventors, it is difficult to transfer an image even if the release layer used in the conventional photosensitive material for image transfer using a photopolymer is used as it is in the above photosensitive material using silver halide. However, in some cases, it could not be transferred at all.

As described above, even if the same release layer is used, in the case of a photosensitive material having a different image forming method from that of a conventional photopolymerization type photosensitive material, the image transferability is completely different. . Therefore, it is absolutely necessary to provide a means for more easily and stably transferring an image.

An object of the present invention is to improve a light-sensitive material utilizing a polymerization reaction by silver halide and to provide a light-sensitive material having high sensitivity and easy image transfer.

Another object of the present invention is to provide a light-sensitive material for image transfer, which can directly produce a color proof from digital image data without going through a lith film.

Further, it is an object of the present invention to provide a light-sensitive material for image transfer, which can be used as a light source for scanning exposure of a laser, especially a laser having a long wavelength.

[0011]

The object of the present invention has been achieved by the following light-sensitive material for image transfer. (1) A photosensitive material comprising a support and a photosensitive polymerizable layer containing a silver halide, a reducing agent and a polymerizable compound, wherein a release layer is provided between the support and the photosensitive polymerizable layer. A photosensitive material for image transfer, characterized in that the release layer contains a fluorine-containing compound in an amount of 1% by weight or more. (2) The photosensitive material for image transfer as described in (1), wherein the release layer has a film thickness of 1.0 μm or more. (3) The photosensitive material for image transfer as described in (1), wherein the release layer contains a binder having a flow softening point equal to or higher than a heating temperature required for the reduction reaction of the reducing agent. (4) The photosensitive polymerizable layer is composed of a photosensitive layer containing silver halide and a polymerizable layer containing a polymerizable compound, and a release layer, a polymerizable layer and a photosensitive layer are sequentially provided on a support ( The photosensitive material for image transfer according to 1). (5) The photosensitive material for image transfer as described in (1), further comprising an overcoat layer provided on the photosensitive polymerizable layer. (6) The photosensitive material for image transfer according to (1), wherein the fluorine-containing compound is a fluorine-containing surfactant. (7) The photosensitive polymerizable layer further contains a coloring agent (1)
The light-sensitive material for image transfer as described in 1. (8) The photosensitive material for image transfer according to (4), wherein the polymerizable layer further contains a colorant.

[0012]

Since the light-sensitive material for image transfer of the present invention uses silver halide as an optical sensor, a high-sensitivity color proof can be directly prepared from digital image data without using a lith film. Silver halide
There is the advantage that a scanning exposure of a laser, in particular a long wavelength laser, can be used as the light source. The image transfer photosensitive material of the present invention is characterized in that a release layer is provided between the support and the photosensitive polymerizable layer. By providing the peeling layer, the image formed on the photosensitive material with high sensitivity using silver halide can be directly transferred to another material such as an image receiving material. Therefore, it is possible to form a clear transferred image having extremely high resolution as compared with the conventional photosensitive material for image transfer using microcapsules. Furthermore, in the present invention, the release layer contains 1% by weight or more of a fluorine-containing compound. According to the study by the present inventors, when the release layer of the conventional image transfer photosensitive material using a photopolymer is applied as it is to the image transfer photosensitive material using the silver halide of the present invention, a non-image portion (uncured portion) is obtained. Although the peelability of) is good, the peelability of the image part (cured part) deteriorates (the force required for peeling increases), making image formation difficult, and sometimes image transfer becomes impossible. Turned out to be. Although the cause has not been clarified, it is a phenomenon peculiar to the image transfer photosensitive material using silver halide, which is not known in the image transfer photosensitive material using a photopolymer. As described above, the photosensitive material for image transfer of the present invention containing 1% by weight or more of the fluorine-containing compound for the peeling layer solves the problem of deterioration of the peeling property and can form a very clear transferred image.

[Reducing Agent] The reducing agent used in the present invention has a function of reducing silver halide or a function of accelerating (or suppressing) the polymerization of the polymerizable compound. There are various kinds of substances as the reducing agent having the above function. Examples of the reducing agent include hydroquinones, catechols, p-aminophenols, p-phenylenediamines, 3-pyrazolidones, 3-aminopyrazoles, 4-amino-5-pyrazolones, 5-aminouracils, 4,5-dihydroxy-6-aminopyrimidines, reductones, aminoreductones, o- or p-sulfonamidophenols, o- or p-sulfonamidonaphthols,

-Sulfonamido-5-pyrazolones, 3-sulfonamidoindoles, sulfonamide pyrazolobenzimidazoles, sulfonamide pyrazolotriazoles,
Examples include α-sulfonamidoketones and hydrazines.
By adjusting the type and amount of the reducing agent, it is possible to selectively polymerize the polymerizable compound in any portion of the silver halide latent image formed portion and the latent image not formed portion. .. For example, the following system (A), (B) or (C) can be adopted.

The reducing agent (A) develops silver halide, and is itself oxidized to an oxidant. When the oxidant decomposes in the layer to generate radicals, polymerization occurs in the portion where the latent image of silver halide is formed. As the reducing agent having such a function, hydrazines can be used alone, or hydrazines and other reducing agents can be used in combination. (B) When the oxidant of the reducing agent has a polymerization suppressing function, by coexisting a polymerization initiator in the system, the polymerization is suppressed in the portion where the latent image of silver halide is formed. Then, polymerization occurs in the portion where the latent image of silver halide is not formed. Examples of the reducing agent having such a function include 1-phenyl-3-pyrazolidones. (C) When the reducing agent itself has a polymerization inhibiting function, but its oxidant does not have a polymerization inhibiting function (or has a weak polymerization inhibiting function), a polymerization initiator is allowed to coexist in the system. By setting, the polymerization is suppressed in the portion where the latent image of silver halide is not formed, and the polymerization occurs in the portion where the latent image of silver halide is formed. Examples of the reducing agent having such a function include hydroquinones. In the system (B) or (C) described above, it is necessary to add a polymerization initiator that decomposes to generate radicals by heating or light irradiation to any layer of the photosensitive material.

Further, as in the light-sensitive material described in JP-A-62-210446, instead of the reducing agent, a reducing agent precursor capable of releasing the reducing agent under heating conditions or in a contact state with a base may be used. . The reducing agent and reducing agent precursor described in the above-mentioned publications and documents can be effectively used for the light-sensitive material in the present specification. Therefore, the "reducing agent" in the present specification includes the reducing agents and reducing agent precursors described in the above-mentioned publications, specifications and literatures. Further, among these reducing agents, those having a basicity to form a salt with an acid can be used in the form of a salt with an appropriate acid. These reducing agents may be used alone, or as described in each of the above publications, two or more reducing agents may be mixed and used. When two or more reducing agents are used in combination, the reducing agent's interaction is as follows. Firstly, silver halide (and / or organic silver salt) by so-called superadditivity.
Secondly, the second is via a redox reaction with another reducing agent in which the oxidant of the first reducing agent produced by reduction of silver halide (and / or organic silver salt) coexists. Inducing the polymerization of the polymerizable compound (or suppressing the polymerization) is considered. However, in actual use, it is difficult to specify which of the above actions because the above reactions can occur simultaneously. The reducing agent is 0.1 per mol of silver halide.
Used in the range of 10 to 10 moles, more preferably 0.5
Is in the range of up to 5 moles. Specific examples of the reducing agent are shown below.

Organic silver salts include organic acid silver salts, triazole silver salts, and the like, "Basics of photographic optics, non-silver salts" (page 247) and JP-A-59-
Organic silver salts described in JP-A Nos. 55429 and 62-3246 can be used.

2,4-triazole and 1H-tetrazole are described in US Pat. No. 4,220,709.

In some cases, instead of the organic silver salt, an organic compound constituting the organic silver salt may be added to the photosensitive layer to obtain the same effect.

The range of ˜5 g / m ² , preferably 10 mg to 0.5 g / m ² is suitable.

[Binder for photosensitive layer] In the case of a laminated type photosensitive material, the binder used in the photosensitive layer may be any binder as long as the characteristics of the photosensitive layer are not significantly impaired. However, since the photosensitive layer contains silver halide, it is preferable to use a hydrophilic binder. The hydrophilic binder is a binder having a hydrophilic group or / and a bond in the molecular structure. Examples of hydrophilic groups include carboxyl groups, alcoholic hydroxyl groups, phenolic hydroxyl groups, sulfonic acid groups, sulfonamide groups, sulfonimide groups and amide groups. Examples of hydrophilic bonds include urethane bonds,
An ether bond and an amide bond can be mentioned.
It is preferable to use a water-soluble polymer and / or a water-swellable polymer as the hydrophilic binder polymer.
A water-swellable polymer has an affinity for water,
The binder itself does not completely dissolve in water because it has a crosslinked structure and the like. As the water-soluble or water-swellable binder, a natural or synthetic polymer compound can be used. Examples of natural polymers include water-soluble polysaccharides (eg, starch derivatives, cellulose derivatives, alginic acid, pectic acid, gum arabic, pullulan, dextran) and proteins (eg, casein, gelatin). These may be artificially modified if necessary. It can also be used after being modified or crosslinked during coating and drying. As the synthetic polymer, a polymer of a water-soluble monomer or a copolymer of this and another monomer can be used. Examples of the water-soluble monomer in this case include a monomer having a chemical structure such as a carboxyl group, an acid anhydride group, a hydroxyl group, a sulfonic acid (salt) group, an amide group, an amino group, and an ether group. Such monomers are described in "Applications and Markets of Water-Soluble Polymers" (CMC 16-18). A copolymer obtained by polymerizing these monomers or crosslinking a polymer obtained by copolymerizing with another monomer can also be used (for example, the copolymer described in US Pat. No. 4,913,998).

As other synthetic polymers, polyvinyl alcohol, polyvinyl ether, polyvinylpyrrolidone, polyethylene oxide and derivatives or modified products thereof can be used. For example, in the case of polyvinyl alcohol, those having various degrees of saponification can be used. Further, copolymer modified polyvinyl alcohol can also be used. The copolymerization modification is a method in which a copolymer of vinyl acetate and another monomer is saponified to obtain modified polyvinyl alcohol. As the monomer to be copolymerized, any monomer can be used as long as it is copolymerized with vinyl acetate. Examples of copolymerizable monomers include ethylene, higher vinyl carboxylates, higher alkyl vinyl ethers, methyl methacrylate and acrylamide. Further, post-modified polyvinyl alcohol can also be used. The post-modification is a method in which a compound having reactivity with a hydroxyl group of polyvinyl alcohol is modified by a polymer reaction. Specifically, the hydroxyl group is modified by etherification, esterification, acetalization, or the like. Furthermore, it is also possible to use crosslinked polyvinyl alcohol. In this case, an aldehyde as a crosslinking agent,
Polyvinyl alcohol is cross-linked using a methylol compound, an epoxy compound, a diisocyanate, a divinyl compound, a dicarboxylic acid or an inorganic cross-linking agent (eg boric acid, titanium, copper). These modified polyvinyl alcohols and cross-linked polyvinyl alcohols are described in "Poval", Vol. 3, Vol. 28, pp. 281-285 and 256-26.
Page 0). The molecular weight of these hydrophilic polymers is preferably in the range of 3000 to 500,000. The coating amount is 0.05 to 20 g / m ² , more preferably 0.1.
The range is from 10 g / m ² .

Oxygen that has penetrated into the polymerizable layer during heat development inhibits radical polymerization or crosslinking. Therefore, the photosensitive layer preferably has a function of preventing the influence of oxygen in the air on the polymerizable layer. For this function, the hydrophilic binder needs to be a substance having a low oxygen permeability, and the oxygen permeability coefficient thereof is 1.0 ×.
It is preferably 10 ⁻¹¹ cc · cm / cm ² · sec · cm · Hg or less. As the polymer having low oxygen permeability, a polyvinyl alcohol polymer, a copolymer of gelatin and vinylidene chloride is preferable. Here, the polyvinyl alcohol polymer means polyvinyl alcohol and modified polyvinyl alcohol (for example, saponified block copolymer of polyvinyl acetate and another monomer). The molecular weight is not particularly limited, but is preferably in the range of about 3000 to 500,000. As a polymer with low oxygen permeability, saponification degree is 5
0% or more, more preferably 80% or more, even more preferably 85% or more polyvinyl alcohol is particularly preferable.

[Colorant] In the present invention, a colorant can be added to the light-sensitive material for the purpose of preventing halation. As the colorant for this purpose, a pigment or a pigment may be used as long as it does not significantly hinder the polymerization and curing reaction of the polymerizable layer or the light sensitivity and developability of the silver halide.
Any known colorant can be used regardless of the dye. When a colorant is added to prevent halation, the colorant must be capable of absorbing light at the exposure wavelength. As the colorant for this purpose, any substance that can be used as a colorant in the present invention can be used. When the colorant is a dye and it is contained in the photosensitive layer or a layer adjacent to the photosensitive layer, the anti-irradiation dye referred to in the silver salt photosensitive material can be used. For these anti-irradiation dyes,

No. 030392 and No. 1100546 are described. The content of the colorant is not particularly limited as long as it does not significantly hinder the polymerization reaction of the polymerizable layer or the light sensitivity and developability of the silver halide. In addition, the appropriate addition amount changes depending on which layer contains the pigment, the pigment or the dye is used. Also, since the appropriate addition amount changes depending on the absorbance of the colorant,
Although it is difficult to unconditionally specify the optimum addition amount,
01 to ² g / m ² , more preferably 0.02 to 1 g / m
^{Is 2} . In the mode of forming an image using a colorant,
When a colorant is used in the polymerizable layer for a light-sensitive material, the color tone of the image changes due to the mixing of the color with the colorant, so the amount added should be kept to the minimum or the amount added to the polymerizable layer should not be added. Addition should be avoided. This is not a limitation in a mode in which an image is formed using toner. These colorants can be contained in any layer of the light-sensitive material. It is also possible to provide a new layer in the light-sensitive material such as a back layer or an intermediate layer, and introduce the new layer into these layers. It can also be added to each of a plurality of layers of the light-sensitive material. Further, two or more kinds of colorants can be used together.

[Polymerization Initiator] The reducing agent used in the light-sensitive material used in the present invention, or the oxidant of the reducing agent produced when the reducing agent reduces silver halide suppresses the polymerization of the polymerizable compound. If it is a working compound,
It is necessary to add a polymerization initiator that generates radicals by heating or light irradiation to at least one layer of the light-sensitive material. As these thermal polymerization initiators or photopolymerization initiators, conventionally known ones can be used.
When a photopolymerization initiator is used, it is necessary to irradiate the entire surface with light after thermal development. The thermal polymerization initiator is, for example, “addition polymerization / ring-opening polymerization” edited by the Society of Polymer Science and the Society for Polymer Experimental Studies Editorial Committee.
(1983, Kyoritsu Shuppan), pp. 6-18. Specific examples of the thermal polymerization initiator include azobisisobutyronitrile, 1,1′-azobis (1-cyclohexanecarbonitrile), dimethyl-2,2′-azobisisobutyrate and 2,2′-azobis.

Examples of the reducing agent (hydrogen-donating compound) used with the photoreducible dye include β-diketones such as dimedone and acetylacetone, triethanolamine, diethanolamine, monoethanolamine, diethylamine, amines such as triethylamine, p-toluene. Examples thereof include sulfinic acid such as sulfinic acid and benzenesulfinic acid and salts thereof, N-phenylglycine, L-ascorbic acid and salts thereof, thiourea and allylthiourea. The molar ratio of the photoreducible dye and the reducing agent is
The range of 1: 0.1 to 1:10 is preferable. As the photopolymerization initiator, commercially available photopolymerization initiators such as “Irgacure-651 and Irgacure-907” manufactured by Ciba-Geigy are also preferably used. The polymerization initiator is 0.00 per 1 g of the polymerizable compound.
It is preferably used in the range of 1 to 0.5 g, and more preferably 0.01 to 0.2 g.

[Adhesive Layer] Depending on the mode of image formation,
An adhesive layer may be provided on the photosensitive material. The adhesive layer needs to be a layer that does not completely dissolve in the eluate during the elution operation. It must also have the ability to adhere colored toner to its surface. The adhesive layer can be constructed of any known substance as long as it satisfies the above two points. As an example of such a layer, a mixed layer of any conventionally known polymer and a compound exemplified as a substance having a plasticizing effect among heat development accelerators, or
A mixed layer of any conventionally known polymer and an oligomer of any conventionally known polymer, or a second-order transition temperature of -1
A layer containing an elastomeric polymer at 0 ° C. or lower can be mentioned. In the last example, the polymer alone can provide the necessary properties, which is advantageous, but the polymer may be used as a mixed layer in which a plasticizer, an oligomer and the like are further added. Specific examples of the polymer used in the adhesive layer include natural rubber and synthetic rubber. As an example of synthetic rubber,
Isobutylene, nitrile rubber, butyl rubber, chlorinated rubber, polyvinyl isobutyl ether, silicone elastomer, neoprene and copolymer rubber (eg, styrene-butadiene copolymer, styrene-isobutylene copolymer)
Can be mentioned. When the polymer is a copolymer, it may be a random, block or graft copolymer.
The thickness of the adhesive layer is preferably 0.01 to 10 μm,
0.05 to 5 μm is more preferable.

[Arbitrarily provided layer] Regardless of the single layer type photosensitive material and the laminated type photosensitive material, an additional layer can be provided in any part of the photosensitive material. For example, a protective layer (or a cover film layer) for surface protection or prevention of polymerization inhibition by oxygen in the air, a back layer for preventing halation or preventing adhesion when the photosensitive materials are stored together. If necessary, an intermediate layer or the like may be provided to improve adhesion between layers or peeling property or prevent halation. Further, when performing transfer to the image receiving material or laminating with the image receiving material, in order to prevent bubbles from being unable to adhere uniformly due to inclusion of a matting agent in the layer in contact with these image receiving materials, A new layer containing a matting agent may be provided. As the matting agent in this case, a conventionally known matting agent can be used. The matting agent may be incorporated in the image receiving material. When the photosensitive material has an overcoat layer, the overcoat layer can be formed as a layer containing an arbitrary polymer by coating in advance. There is no particular limitation on the material of the polymer used for these overcoat layers. For example, a hydrophilic binder polymer that can be added to the photosensitive layer can be used. Of these, various polyvinyl alcohols are particularly preferably used. When it is desired to impart a function of reducing oxygen permeation to the overcoat layer, the saponification degree of polyvinyl alcohols is 85%.
When it is desired to impart higher oxygen impermeability to the above polyvinyl alcohol, it is preferable to use polyvinyl alcohol having a saponification degree of 95% or more. Also,
The overcoat layer is not limited to only one layer, but 2
It is also possible to stack and install more than one layer.

The oxidant radicals (87) of the reducing agent move from the exposed areas (85) of the photosensitive layer to the exposed areas (83) of the polymerizable layer. The polymerizable compound is cured by the action of this radical to form a cured portion (83). On the other hand, there is no substantial change in the reducing agent (86) contained in the unexposed portion of the polymerizable layer and the silver halide (88) contained in the unexposed portion of the photosensitive layer. The unexposed area (82) becomes an uncured area.

FIG. 9 is a schematic sectional view showing the elution step in the third embodiment of the image forming method. The eluate (91) is used to remove the uncured portion of the polymerizable layer, thereby forming a colored image on the cured portion (92). The photosensitive layer is peeled off and removed before the elution step, or is removed together with the uncured portion of the polymerizable layer in the elution step using an eluent.

FIG. 10 is a schematic sectional view showing a transfer step in the third embodiment of the image forming method. FIG. 10 shows a state after transfer. The light-sensitive material (102) is transferred to the image receiving material (10
The colored image (103) formed on the cured part of the polymerizable layer is transferred to the image receiving material together with the peeling layer (104).

The above is a typical embodiment of the image forming method using the light-sensitive material of the present invention. In image formation, in addition to the above steps, additional steps can be added if necessary. In the case of a laminated type light-sensitive material, a step of removing a layer disposed above a polymerizable layer such as a photosensitive layer is necessary before the elution step (after the development step) or at the same time as the elution step. This layer may be removed by peeling. Alternatively, the layer above the polymerizable layer may be removed by elution or swelling with a liquid that does not dissolve the polymerizable layer. Further, in the elution step, an eluent may be used to remove together with the uncured portion of the polymerizable layer. Further, the step of transferring the monochromatic image formed on the image receiving material to another image receiving material may be further performed. A step of transferring a color (multicolor) image formed on the image receiving material to another image receiving material can also be performed. When transferring an image, the image is turned over (reverse image). When the final color image is formed on the transparent support, the image may be turned over, but when the color image is formed on the opaque support, the final image needs to be formed as a desired normal image. Is. For this reason, it is necessary to appropriately perform an operation such that the exposure is performed inside out, or another transfer is performed to return the reverse image to the normal image. When adding the above-mentioned improper transfer step, it is necessary to consider such a relationship between the normal image and the reverse image. In addition, optional steps such as a step of removing additional layers such as an intermediate layer and a back layer, a matting step on the surface of the image-receiving material on which an image is formed, and a step of applying a matting agent to the image-receiving material are added. be able to.

Each step of the image forming method will be described in more detail. [Exposure Step] Image exposure in the exposure step may be performed from the surface side of the photosensitive material (the side opposite to the support) or from the support side. Examples of the exposure method for image exposure include reflection image exposure using a xenon lamp, tungsten lamp, fluorescent lamp or the like as a light source, contact exposure through a transparent positive film, and laser beam, scanning exposure with a light emitting diode or the like. The light-sensitive material of the present invention is
The feature is that an image can be formed by drawing by scanning exposure. Therefore, the present invention is particularly advantageous when using scanning exposure. Scanning exposure includes helium-neon laser, helium-cadmium racer, argon ion laser, krypton ion laser, YAG laser, ruby laser, nitrogen laser, dye laser, excimer laser, semiconductor (eg, GaAs / GaAlAs, InGaAsP) laser. , Alexandrite laser, copper vapor laser,
A laser light such as an erbium laser can be used as the light source. Further, scanning exposure using a light emitting diode or a liquid crystal shutter as a light source (including a line printer type light source using a light emitting diode array, a liquid crystal shutter array, etc.) is also possible. The light source or exposure wavelength that can be used for image exposure depends on the light-sensitive region of the silver halide emulsion used in the light-sensitive material, and the wavelength region of near-ultraviolet light, visible light, and near-infrared light can be used. The amount of exposure depends on the sensitivity of the silver halide emulsion and is 0.01 to 100.
It can be exposed with light energy of 00 erg / cm ² . By performing the above image exposure, a latent image of silver halide is formed in the exposed portion.

[Developing Step] In the image forming method, it is preferable to use a dry developing process for heating the photosensitive material. The developing process can be performed at the same time as the exposing process. The imagewise exposed light-sensitive material is heated by a conventionally known heating means. For heating, the photosensitive material is brought into contact with a heated object (for example, a roller, a flat plate, etc.), or the photosensitive material is heated by infrared irradiation, or the photosensitive material is left in a heated zone or passed through the zone. Contact-type and non-contact-type heating means such as heating can be used. Further, at the time of heating, the surface of the light-sensitive material may be brought into close contact with an arbitrary object without being exposed to the air, and the surface may be covered and heated. The temperature and heating time required for heating depend on the characteristics of the photosensitive material used. Generally, the heating temperature is preferably in the range of 70 ° C to 200 ° C. The heating time is preferably in the range of 1 to 180 seconds. In addition, in image formation, a wet development process using a developing solution can be performed. In the developing step, the silver halide on which a latent image has been formed by exposure is developed, and at the same time, an oxidant of the reducing agent is formed at that portion. When the oxidant of the reducing agent has a polymerization accelerating effect, the exposed area is selectively cured, and when the oxidant of the reducing agent has a polymerization inhibiting effect, the polymerizable compound in the unexposed area is selectively cured. When a photosensitive material containing a photopolymerization initiator as a polymerization initiator is used in a system for curing a portion (unexposed portion) where a latent image is not formed, the photosensitive material is entirely exposed after the developing step.

[Elution Step] (Third to Eighth Aspect) In the developing step, the photosensitive polymerizable layer (in the case of a laminated type photosensitive material) is
The exposed or unexposed areas are selectively cured. As a result,
The solubilities of the hardened part and the uncured part with respect to the eluent change, and the hardened part is not eluted with the eluent, but the uncured part is eluted with the eluent to form an image on the photosensitive material. The eluent (or etching solution) for removing the uncured part is
Any solvent can be used as long as it can remove the uncured portion of the (photosensitive) polymerizable layer. Preferably an alkaline solvent is used. The alkaline solvent is an aqueous solution containing an alkaline compound, an organic solvent containing an alkaline compound, or a mixture of an aqueous solution containing an alkaline compound and an organic solvent. As the alkaline compound, various organic and inorganic compounds can be used. Examples of the alkaline compound, sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, potassium silicate, sodium metasilicate, potassium metasilicate, sodium phosphate, potassium phosphate,
Ammonia and amino alcohols (eg, monoethanolamine, diethanolamine, triethanolamine) can be mentioned. As the solvent of the eluate, water or various organic solvents can be used as described above. The solvent of the eluate is preferably mainly composed of water. If necessary, an organic solvent can be added to the eluate mainly containing water. As the organic solvent, alcohols or ethers are preferable. Examples of alcohols include lower alcohols (eg, methanol, ethanol, propanol, butanol), alcohols having an aromatic group (eg, benzyl alcohol, phenethyl alcohol), polyhydric alcohols (eg, ethylene glycol, diethylene glycol, triethylene). Glycol, polyethylene glycol) and amino alcohols (eg, monoethanolamine, diethanolamine, triethanolamine). Examples of ethers include cellosolves. The eluate is
A surfactant, a defoaming agent, and other various additives may be included as necessary.

[Removing Step] (Ninth to Fourteenth Aspects) In the developing step, the photosensitive polymerizable layer (polymerizable layer in the case of a laminated type photosensitive material, the same applies hereinafter) is selectively exposed or unexposed. Hardens. As a result, the adhesive force between the photosensitive polymerizable layer and the interface of the photosensitive material on the support side changes between the uncured portion and the cured portion. When the removing sheet is brought into close contact with the surface of the photosensitive polymerizable layer of the photosensitive material, the adhesive force between the photosensitive polymerizable layer and the interface of the removing sheet also differs between the uncured portion and the cured portion. When the photosensitive material and the removal sheet are peeled off, the adhesive force at the interface between the uncured part and the support side of the photosensitive material is greater than the adhesive force at the removal sheet side, and the adhesion between the cured part and the support side of the photosensitive material is at the interface. When the force is smaller than the adhesion force with the removal sheet side, only the cured portion is transferred to the removal sheet. vice versa,
The adhesive force at the interface between the uncured portion and the support side of the photosensitive material is less than the adhesive force at the removal sheet side, and the adhesive force at the interface between the cured part and the support side of the photosensitive material is less than the adhesive force at the removal sheet side. When large, only the uncured portion is transferred to the removal sheet. Whether the cured portion is transferred or the uncured portion is transferred depends on the nature of the polymerizable compound in the photosensitive polymerizable layer, the amount of the polymerizable compound added, the nature of the binder in the photosensitive polymerizable layer,
Since the above adhesive force varies depending on the properties of other components in the photosensitive polymerizable layer and the amount thereof added, as well as various conditions of the removal process (heating temperature, time, pressurizing temperature, etc.). sell. As a result of the above, the cured portion or the uncured portion selectively remains in an image form. In the ninth and tenth aspects, a color image is formed on the photosensitive material. In the eleventh and twelfth aspects, the adhesive layer is imagewise exposed, and colored toner is adhered to this to form a toner image.
In the thirteenth and fourteenth aspects, the uncured portion having adhesiveness is formed in an image shape, and the colored toner is attached thereto. The removal sheet used in the removal step may be art paper, coated paper, printing paper, or plastic sheet. The surface of these may be coated with a resin binder, a plasticizer, a surface treatment agent, a matting agent, or the like in a single layer or multiple layers. The removal sheet can be made using the same material as the image receiving material described later.

[Transfer Step] (First, 3, 5, 7, 9, 11 and 13
Aspect) In the transfer step in the third and ninth aspects,
The image-receiving material and the image-like cured surface of the light-sensitive material are brought into contact with each other, and pressure or heat or both pressure and heat are applied thereto to perform transfer. In the transfer step, the release layer is transferred to the image receiving material together with the photosensitive polymerizable layer (in the case of a laminated type photosensitive material, the polymerizable layer, the same applies hereinafter). Other adjacent layers (such as an undercoat layer) may be simultaneously transferred to the image receiving material. The transfer conditions such as the transfer temperature and the transfer pressure in this transfer step can be changed depending on various factors such as the properties of the photosensitive polymerizable layer and the material of the image receiving material. Generally, the transfer temperature is 1
The transfer pressure is preferably 0 to 200 ° C., and the transfer pressure is 0.
To 2000 kg / cm ² is preferable. In the transfer steps in the first, fifth, seventh, eleventh and thirteenth aspects, the image receiving material and the surface of the photosensitive material to which the colored toner adheres are brought into contact with each other, and pressure or heat or pressure and heat is applied thereto. Transcription is performed over both. In the transfer step, what is transferred to the image receiving material is the colored toner, the photosensitive polymerizable layer and the peeling layer. Further, another layer (undercoat layer or the like) adjacent to the photosensitive polymerizable layer may be simultaneously transferred to these. The transfer temperature and transfer pressure vary greatly depending on the material of the image receiving material, the material of the colored toner, and the properties of the photosensitive material. Generally, the transfer temperature is preferably 10 to 200 ° C., and the transfer pressure is 0 to 2000 kg /
It is preferably cm ² . As the image receiving material used in the transfer step, art paper, coated paper, printing paper and plastic sheet can be used. The surface of these may be coated with a resin binder, a plasticizer, a surface treatment agent, a matting agent, or the like in a single layer or multiple layers.

[Toner Developing Step] (First, Second, 5th to 8th and 11th to 1st)
Aspect 4) The toner development is performed by sprinkling a colored toner on the surface of the photosensitive polymerizable layer or the adhesive layer and physically contacting the surface with a cloth or sponge. The toner developing step can also be performed using an automatic toner developing device such as an automatic toning machine type 2900 manufactured by DuPont. The method of forming a colored image by bringing colored toner into contact with the adhesive surface as described above is described in JP-B-48-31323, JP-A-59-104665 and JP-B-1-36611. There is.

For example, the image receiving material and the photosensitive material may be brought into close contact with each other and laminated between them by an operation such as passing them between rubber rollers. Also, other conventionally known laminating methods can be used in the laminating step. The image receiving material used in the laminating step is not particularly limited in material as long as it can stably hold a film having a thickness of about 5 to 50 μm.

Next, while applying a 75 μm thick polyethylene terephthalate film to the overcoat layer side, an iron plate heated to 140 ° C. was pressed against the back surface of the support to heat it. This reduces the silver halide and simultaneously hardens the polymerizable layer.

(Preparation of Color Proof) A color proof was prepared as follows according to the first embodiment of image formation, using the above-mentioned photosensitive material for image transfer. Using an air-cooled argon ion laser as a light source, a yellow image-forming exposure was performed by scanning exposure (exposure amount on film surface: 10 μJ / cm ² ) at an exposure wavelength of 488 nm. Then this one
Thermal development was carried out by heating the plate in close contact with a hot plate heated to 30 ° C. for 40 seconds. Next, the layer above the photosensitive layer was peeled from the interface between the polymerizable layer and the photosensitive layer to expose the polymerizable layer. When the yellow toner was applied to the surface of the polymerizable layer while rubbing lightly, the toner adhered only to the unexposed area, that is, the uncured area, and a yellow image was formed on the photosensitive material. In the same manner, another photosensitive material is exposed to form a magenta image, heat-developed and peeled off, and then the magenta toner is lightly rubbed and adhered thereto.
A magenta image was formed on the light-sensitive material. In the same manner, another photosensitive material is exposed for cyan image formation,
After thermal development and peeling, the above cyan toner was lightly rubbed and adhered to form a cyan image on the photosensitive material. In the same manner, another light-sensitive material is exposed to light for forming a black image, subjected to heat development, peeling, and elution, and then the black toner is lightly rubbed and attached to form a black image on the light-sensitive material. did. Next, a yellow image-formed photosensitive material is first brought into close contact with an image receiving material made of art paper, and heated to about 100 ° C. to form a yellow toner image as an image receiving material together with the polymerizable layer and the peeling layer of the photosensitive material. It was transcribed. Similarly, a photosensitive material having a magenta image formed thereon is brought into close contact with the image receiving material to which the yellow image has been transferred, and heated to about 10 ° C., so that the magenta toner image is received together with the polymerizable layer and the peeling layer of the photosensitive material.
