More specifically, it is an image forming material formed by superimposing a single color or a multicolor using the difference in adhesiveness between an exposed portion and an unexposed portion of a photosensitive layer, and as a prepress proof for color proofing, obtains a transferred material similar to a printed material.

Description of the Related Art In the printing industry, it has been known to use a prepress proof as a means for confirming the finish, color tone, and the like of a finally printed product before printing. The prepress proof includes an overlay method and a surprint method, and the prepress proof is used depending on the image quality to be finally obtained and the purpose of use in plate making and printing processes. In the overlay method, a film in which a photosensitive layer containing a color material corresponding to a color separation mask is provided on a transparent base film is brought into close contact with the mask, exposed and developed, and the respective films are overlaid. Perform calibration.

しかしながら,有機溶剤による現像工程が必要なために
作業環境が悪くなる欠点がある。[0003] The surprint method has a high utility value since a hard copy is obtained unlike the overlay method, and for example, as described in US Patent Nos. 3060023, 3060024 and 3060025. In this method, several layers of photopolymer-photosensitive layers are laminated on a single support to sequentially form color-separated images. Also, JP-A-59-97410,
There is also a prepress proof that can be used for both the overlay method and the surprint method as described in Japanese Patent Application Laid-Open No. Sho 61-1885377. In this method, if you just want to check characters, etc., according to the purpose of use, check with only overlay, and if you want to obtain hard copy for checking subtle color parts such as patterns, etc. The versatility is great in that it can be transferred to a transfer target.
However, there is a disadvantage that the working environment is deteriorated due to the necessity of a developing step using an organic solvent.

ながら転写する。On the other hand, the present inventors have formed a photosensitive layer containing a dye and / or a pigment on a transparent support, exposed the image, and carried out the adhesion of the exposed portion and the unexposed portion of the photosensitive layer during transfer. An image-forming material, which transfers an image to an image receptor, such as paper, which causes a difference in properties between the roll nip and the prepress pull obtained by transferring the image to the image receptor by cohesive destruction of the photosensitive layer between the roll nips Unlike conventional pre-press proofs, the image and texture look very similar to the actual printed matter because there is no layer such as an adhesive layer between the printing material and the image forming material, unlike the conventional prepress proof. Has already been found. These image-forming materials usually comprise three layers: a transparent support (1), a photosensitive layer (2) containing a dye and / or a pigment, and a protective film (3). When using the image forming material, the transparent support (1) is brought into close contact with the image surface of the mask master, and the image is exposed from the mask side.
Remove the mask master and then the protective film (3), and remove the photosensitive layer.
(2) The image and the image receptor are transferred between the nipples while applying heat and pressure.

及ぼす等の欠陥が生じる。In the protective layer (3) of the three-layered image forming material described above, if an appropriate gas barrier property does not exist, a photopolymerization initiator and / or a photosensitizer which are constituents of the photosensitive layer (2) are provided. The sensitizer may migrate into the protective layer, causing a decrease in image sensitivity and the like, which may cause defects such as a significant decrease in storage stability. Also, when transferring the photosensitive layer to an image receptor such as paper, a protective layer is not required and must be removed from the surface of the photosensitive layer before transfer. In this case, a suitable protective layer surface is in contact with the photosensitive layer surface. If the releasability is not added, defects such as migration of the photosensitive layer to the surface of the removed protective layer occur. Further, when the rigidity of the image forming material is insufficient,
When a punch system is used, the suitability of the punch decreases, or during a series of operations such as exposure, the occurrence of a defect in the image forming material called a helicopter or a decrease in workability is caused.
Furthermore, defects such as affecting the image quality and registration accuracy of the finally obtained image occur.

た。The results of various tests and evaluations using the image forming materials obtained in Examples 1 to 3 and Comparative Examples 1 and 2 are shown in Table 1. The evaluation was based on six points: stability of image sensitivity when stored at 25 ° C and 40 ° C, presence or absence of migration of the photosensitive layer when the protective layer was removed, suitability for punching, handleability during work (frequency of occurrence of dents), and registration accuracy. went. Tests and evaluations of image sensitivity stability at 25 ° C and 40 ° C storage were performed by tracking the number of clear steps in the step guide of the images obtained by transfer over time. The transfer is performed by bringing the support side of the image forming material into close contact with the emulsion surface of a plate control wedge (original positive mask PCW manufactured by UGRA) having a step guide, and using an exposure machine P-627-FM (manufactured by Dainippon Screen). so
After reducing the pressure for 30 seconds, an actinic ray of 65 mj / cm 2 was applied from the positive mask side of the original plate, the plate control wedge was removed, the protective layer was removed, and a special transfer machine (transfer temperature 95 ° C / 40

When the image-forming material was attached to a photoreceptor (40 ° C.) and the protective layer was removed, the presence or absence of migration of the photosensitive layer was visually determined. Punch suitability test and evaluation were performed by punching the obtained image forming material with a punch table (Kamata Seisakusho) and attaching it to a pin bar (Kamata Seisakusho KFP-25). Judgment was made based on whether there was any change. In the test and evaluation of the handling properties during the work, a series of work from image exposure to mounting on the image forming material mounting roll of the dedicated transfer machine was performed for each image forming material of 670 mm × 680 mm. Judgment was made based on the number of cats that occurred spontaneously (frequency of occurrence of cats). In the test and evaluation of register accuracy, the above steps from exposure to transfer are performed on the same art paper using an original positive mask with register marks for registration (art paper is fixed on a transfer roll on a dedicated transfer machine). ) Was repeated twice, and the judgment was made based on the deviation amount of the two register marks.

Control of the surface tension of the protective layer surface in contact with the surface of (2)
By increasing the rigidity of the image forming material, the storage stability of the image sensitivity over time, the release stability when removing the protective layer, the prevention of loss of the image forming material, such as a crust, and the improvement of workability can be remarkably made. Further, it is possible to stabilize the image quality, registration accuracy, and the like of the final image, thereby achieving creation of an image such as a color proof having high reproduction stability.
