Abstract

PURPOSE:To stabilize size variation in a photosensitive material by using a photosensitive material having a size change of a specified value or less between before and after processing, when the silver halide photographic sensitive material is exposed to light under an environment specified in temperature and humidity and dried at a specified temperature after development, and automatically controlling temperature and humidity of a drying air stream. CONSTITUTION:The silver halide photographic sensitive material is exposed under the environment of a temperature of 23 deg.C and a relative humidity of 40%, and developed and dried at a temperature of 45 deg.C in the automatic developing machine, and the photosensitive material having a size change of <=+5.5X10<-3> between before and after the processing is used and the temperature and humidity of the drying air stream is automatically controlled. The photosensitive material having such characteristics can be obtained by properly controlling the drying conditions after coating with the hydrophilic colloidal layers, such as silver halide emulsion layers, and the heat treatment conditions after the drying and the like, thus permitting the size variation of the photosensitive material before and after the processing of the automatic developing machine to be stabilized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for processing a silver halide photographic material, in which processing from development to drying is performed using an automatic processor.

``Prior Art'' Current silver halide photographic materials have the characteristic of ``shrinking'' when the humidity is low and ``stretching'' when the humidity is high.

Apart from this, the photosensitive material has the characteristic that its dimensions change before and after processing. This is a phenomenon in which the image dimensions on the photographic light-sensitive material and the photographic light-sensitive material at the time of exposure of the photographic light-sensitive material (equal to the original size) are different from the image dimensions on the photographic light-sensitive material and the photographic light-sensitive material after development processing, and 'R It is affected by the temperature and humidity conditions at the time of light and the dry area and humidity conditions during processing.

The latter results in different dimensions of the original and the duplicate photographic light-sensitive material, resulting in the following problems.

In particular, a photosensitive material original plate for color printing is composed of three original plates of cyan, magenta, and yellow, or four original plates including a black plate, and therefore, dimensional stability is required as a set of original plates. The photographic light-sensitive materials that are used to create original plates for color printing currently on the market have the above-mentioned characteristics regarding temperature and humidity. , drying conditions (temperature,
Dimensional changes before and after processing caused by changes in humidity (humidity) are often a problem.

For example, when a photographic light-sensitive material that has been exposed and developed as a cyan plate is used as a manuscript, and the pattern of the magenta plate is aligned and then exposed and developed, there is a problem that a dimensional discrepancy occurs between the resulting magenta plate and the original cyan plate. happens.

Even in processing using conventional automatic processors, the drying air recycling vehicle (the ratio of the amount of outside air taken in as dry air circulated within the drying section) is changed according to the external environmental humidity, from the outlet to the entrance of the drying section. It is well known to control the drying air by creating a temperature gradient towards the opposite direction, dehumidifying the air used for drying, etc., but such control is aimed at improving drying efficiency, saving energy, preventing uneven drying, etc. However, no consideration was given to dimensional stability.

By the way, it has been known that there is a close relationship between the drying conditions of an automatic processor and the dimensional change before and after processing.

For example, Japanese Patent Laid-Open No. 1-230035 discloses drying at a lower drying temperature so that the moisture content of the photosensitive material is equal to or higher than equilibrium with the outside air. However, in reality, the physical properties of the membrane change depending on the treatment process, so if the water content is in equilibrium with the outside air, the inventors
As shown in No. 77882, drying with air that is more humid than outside air at a relatively high temperature (for example,
5° C. (35%) can have a revolutionary effect on increasing the dimensional stability of photosensitive materials after processing.

However, depending on the type of photosensitive material and the drying capacity of the automatic processor, the
% environment, the dimensional change before and after processing of the photosensitive material is always within ±5.5 × 10-3%, or -5,0 × 10
It has been found that there are cases where it is not possible to control the amount of shrinkage of the photosensitive material to within 1.1 x 10-3%, which is on the shrinking side of -3% and under such an environment, the deviation width of the dimensional change before and after processing of the photosensitive material. Ta.

Here, 1 dimensional variation difference within ±5.5 × 10-3% is normal control that brings the dimensional variation difference of photosensitive materials close to 0, but ±0 is not necessarily the desired dimensional variation amount for the user. For example, when considering enlargement of an image by exposing it to a point light source, etc., -
It may be preferable to shrink more than 5,O x 10-3%, and in this case, the dimensional variation difference is on the shrinkage side than -5,O x 10-3% and within 1,IX IG-3%. This is because it is necessary to perform control.

[Object of the Invention] The present invention was created in view of the above, and is based on the relationship between external environmental humidity (environmental humidity at the time of exposure of a photographic light-sensitive material) and the dimensional change characteristics of the photographic light-sensitive material to be processed. The main purpose of this study is to clarify the processing method for photographic light-sensitive materials that can set the optimal drying conditions and stabilize the dimensional changes of the photographic light-sensitive materials before and after processing. °C) ±5 under 20-60% environment

When using a silver halide photosensitive material with an OX value of 10-3% or less, and taking into consideration image enlargement due to exposure with a point light source, etc., the desired dimensional change value before and after processing is -5,O × 10-3% on the shrinkage side, and the variation in the width of the dimensional change before and after processing of the photosensitive material under this environment is 1

A photosensitive material having the above characteristics can be obtained by appropriately adjusting the drying conditions after coating a hydrophilic colloid layer such as a silver halide emulsion layer and the heat treatment conditions after drying. At least one photosensitive silver halide emulsion layer containing silver oxide and a binder such as gelatin is coated, and at least one non-photosensitive hydrophilic colloid layer is coated on the other side of the support. In the step of applying at least one of the coating layers, gelling the binder such as gelatin by cooling, and drying, the average surface temperature of the coating layer is 1°C lower than the average temperature of the environmental air to be dried. Within 5 minutes of rising to a low temperature, 35
~80°C and/or It is preferably obtained by contacting air at 30 to 80°C for 5 seconds or more in a packaged state, and more preferably, the packaging ends when both sides are dried. The process up to this point was carried out in contact with ambient air with a dew point temperature of 18°C or lower.

More preferably, after the coating is finished, after the coated surface is once cooled to 30° C. or less, and before being packaged, and/or after being packaged, and before being packaged, and/or in the packaged state. 30-80℃ air and/or relative humidity 1
~25%.

In this specification, packaging is usually sealed in a bag that does not allow air to enter or exit from the outside, or wrapped in a roll of light-shielding vinyl or aluminum foil. At this time, it can be considered that the photosensitive material continues to come into contact with the atmosphere of the packaging process until the packaged product is opened. Furthermore, if the photosensitive material is packaged together with cardboard, etc., the cardboard will be removed during the packaging process. It is preferable that the humidity is controlled to be lower than the humidity.

Furthermore, the air for drying the photosensitive material refers to air that is brought into substantial contact with the photosensitive material, is supplied for the purpose of drying or humidity control, and is air that directly hits the photosensitive material. It does not refer to the air that exists between photosensitive materials that are rolled up into a roll after being coated and dried, or between photosensitive materials that are cut to a desired size and stacked one on top of the other.

Furthermore, the period from the end of coating to the end of packaging includes steps such as winding, cutting, and packaging, and may also include processes such as storage and transportation of the photosensitive material. Note that the air that is in substantial contact with the photosensitive material is air that is in contact with the photosensitive material in a state where the photosensitive material does not come into contact with any substance other than air.

In particular, when transporting the photosensitive material, it was wound into a roll. It is often carried out in a so-called bulk state, or in a state in which the photosensitive materials are stacked after being cut to a desired size.In such a state, for example, in a bulk state, both sides of the support are bonded to each other. The part that is in contact does not substantially come into contact with the ambient air in which the bulk is placed, so the temperature is the same as that of the ambient air, but...
It can be assumed that the humidity of the air is not affected by the ambient air.

That is, after coating and drying is completed, the film is brought into contact with air having a dew point of 18° C. or lower and wound into a roll.

Even if the bulk is transferred in air with a dew point of 16°C or higher and undergoes the cutting and packaging process while coming into contact with air with a dew point of 18°C or lower, it is also included in the state of a dew point of 18°C or lower. It is.

The silver halide contained in the photosensitive emulsion layer in the present invention is not limited to its type, manufacturing method, crystal habit, dispersibility, etc., and the binder of the hydrophilic colloid layer containing the photosensitive emulsion layer is gelatin. is a typical example, but it is not limited to this.

In addition, the thickness of the photosensitive material processed in the present invention is 50 to 30
It is preferable that the intestine is 0JL, and the thickness here means:
The support and all the layers coated on the support (not just the layer coated with the photosensitive layer).

If a backing layer is applied, include the calendar on this side. ), and the thickness referred to herein is defined in the state of what is called a so-called raw photographic light-sensitive material before being subjected to development processing.

Strictly speaking, the thickness before and after the development process does not necessarily match, but this variation in thickness is sufficiently small compared to the thickness in the embodiment of the present invention.

It has also become clear in the course of research by the present inventors that the present invention may be defined by the thickness of the raw photographic light-sensitive material.

Here, from the viewpoint of ease of use and transportability, the preferred thickness of the support is 25#L~25#L, which does not include the subbing layer.
280 degrees, more preferably 40 degrees to 250 degrees.

The support used in the present invention is preferably a cellulose ester film such as cellulose triacetate, a polyester film such as polyethylene terephthalate film, or paper coated with an α-olefin polymer. A film coated with an adhesive layer in a releasable state can also be used.

Furthermore, to explain in detail the polyester mentioned here, it is a polyester whose main constituents are aromatic dibasic acid and glycol, and representative dibasic acids include terephthalic acid, isophthalic acid, and p-β-oxyethoxy. Benzoic acid, diphenylsulfonedicarboxylic acid, diphenoxyethanedicarboxylic acid, adipic acid, sebacic acid, acelaic acid.

5-sodium sulfoisophthalic acid, diphenylene dicarboxylic acid, 2,6-naphthalene dicarboxylic acid, etc.
Glycols include ethylene glycol, propylene glycol, butanediol, neopentylene gelylcol, l,4-cyclohexanediol, 1,4-cyclohexane dimetatool, 1,4-bisoxyethoxybenzene, bisphenol A, diethylene glycol,
Examples include polyethylene glycol. These polyester films can be produced using a known biaxial stretching method, such as that described in JP-A No. 52-54428.

When using any of the above-mentioned supports as constituent elements of a silver halide photographic light-sensitive material, they are subjected to various treatments in order to have strong adhesion between them and a hydrophilic colloid layer containing a binder such as gelatin. It can be applied singly or in combination of two or more.

For example, the surface may be treated with chemicals, mechanical treatment, corona discharge treatment, flame treatment, ultraviolet treatment, or high frequency treatment.

Surface activation treatments such as glow discharge treatment, active plasma treatment, laser treatment, mixed acid treatment, ozone oxidation treatment, acid component, hydroxyl group component, epoxy group component, N-flukanol group component, diolefin monomer component, polymer These methods include coating a subbing layer containing one or more components selected from latex components and the like. In addition, it is also permissible to use known means for preventing static electricity independently from this. For example, fluorine-based surfactants, various conductive polymers, inorganic oxides, organic antistatic agents, etc. may be used in the undercoat layer. This includes a method of making it contain.

These treatments may be performed on only one side of the support or on both sides, and of course, the treatment applied to one side of the support may be applied to the other side. The process may be different from the process that is applied to the other side, and two or more different types of processes may be used together.

In addition, one of the photosensitive materials used in the present invention is JP-A-1-23
Any of the photographic additives described in No. 0035 and the like can be preferably used.

In the present invention, even for the same type of photosensitive material, the amount of dimensional change varies depending on the type of automatic processing machine used for processing, so the value should originally be defined by the combination of the photosensitive material and the automatic processing machine. However, it is impossible to set the dimensional characteristics of a photosensitive material according to the characteristics of each automatic processor, so the inventors usually use automatic processors commonly sold on the market. Unexamined Japanese Patent Publication No. 1 as a photosensitive material
It has been found that the above-mentioned problems can be solved by applying the manufacturing conditions for the photosensitive material disclosed in No. 230035 to obtain a photosensitive material that satisfies the above-mentioned characteristics.

[Example] Examples of the present invention will be described below.

FIG. 1 is a schematic diagram showing a typical example of an automatic processor to which the method of the present invention is applied, in which a film F to be processed is housed in a magazine or the like, for example, and mounted on an apparatus frame. It is set in the insertion part 3 prepared on the side surface of 2.

After setting the magazine 1, when the start button is turned on, the film detecting means confirms the existence of the film to be processed, and the end of the film is engaged with the take-in roller 4 by the rotation of the film ejection roller, and the following steps are performed. The developer tank 6 and the fixing #I are sequentially rotated by the 5 groups of conveying rollers.
I7, and is guided to the washing tank 8 and processed.

After the film has been washed with water, it is guided to the squeeze section and drained, then guided to the drying section 10, where it is dried, and is discharged out of the apparatus through the film discharge port as shown by the arrow.

11 is a drying fan, 12 is a heater, L3 is a drying rack,
14 is a drying duct, and 15 is an exhaust fan.

16 is a drying air humidity sensor, 17 is a temperature sensor, and both sensors are connected to the drying fan 11 in the automatic developing machine.
Although it is preferable to provide the drying air near the outlet of the drying air, it may be provided in other circulation paths of the drying air.

A humidifying device 18 is provided at the outlet of the drying fan 11, but it may also be provided in another circulation path for drying air or near the external air intake.

18 is a dehumidifying device, which connects the drying duct 14 with a pair of pipes.
It dehumidifies the dry air.

20 is a control unit, which has an outside air humidity sensor 21 and an outside air temperature sensor 22.

In this example, the outside air temperature/humidity sensor was installed in the automatic processing machine, but if the exposure machine and the automatic processing machine are in environments where the temperature and humidity are different, for example, when the reprocessing equipment is installed in a separate room, Temperature and humidity sensors are also installed near the exposure machine.

In this case, the temperature and humidity conditions of the drying air are determined based on information from a temperature and humidity sensor near the exposure machine. The outside air temperature and humidity sensor attached to the automatic processor is used to obtain information on the temperature and humidity of the air taken in as drying air when controlling the temperature and humidity of the drying air. There is no need for a temperature/humidity sensor attached to the automatic developing machine.

Hereinafter, the processing method of the present invention using the above-mentioned apparatus (see FIG. 1) will be explained together with experimental data.
