As is known, two or more antioxidants can be used together in a harmonious manner.

In addition, the film thickness of the photosensitive photoresist layer 1 to the resist layer depends on the target optical density, the type of coloring agent (dye dye, coloring agent, carbon black) used in the photosensitive photoresist layer 1 and its content. Although it can be determined by a method known to those skilled in the art, as long as it is within an acceptable range, the thinner the thickness of the photosensitive photoresist layer is, the higher the resolution will be, and the better the image quality will be.

Therefore, the film thickness is preferably used in the range of 0.1 (J/m' to 50/v).

The colored imaging materials of this invention are developed after imagewise exposure through a color separation net film to form a colored image which is imagewise removed. Substantially only the image portion of the obtained colored image is transferred onto the transfer material, IFffl. in this case,
In order to efficiently transfer the image onto the surface to be transferred and to easily peel off the support after image transfer, the support is provided with a release surface treated with a suitable oil-repellent material. Good too.

As the oil repellent substance, for example, silicone resin, fluororesin, fluorine surfactant, polyolefin, polyamide, etc. can be used.

Among the above examples, polypropylene films and polyethylene films in particular exhibit good mold release properties without special mold release treatment, so in a particularly preferred embodiment, the polypropylene film or polyethylene film is thinner than the thickness of the support. An example is to provide a.

The method for forming a polypropylene layer or a polyethylene layer on a support is as follows: 1) Using a solution of polyvinyl acetate, polyvinyl chloride, epoxy resin, polyurethane resin, natural rubber, synthetic rubber, etc. dissolved in an organic solvent as an adhesive.

The so-called hot melt lamination method.

3> The so-called extrusion lamination method, in which polypropylene or polygrene is kept in a molten state and extruded into a film using an extruder, and while this is in the molten state, a support is crimped and laminated.

4) When forming a support film using a melt extrusion method, multiple extruders are used to form a polypropylene layer or a polyethylene layer on the support film in a single molding process with polypropylene or polyethylene in a molten state. This is the so-called co-extrusion method. etc.

As the support for the colored image-forming material used in the present invention, polyester films, particularly biaxially oriented polyethylene terephthalate films, are preferred from the viewpoint of dimensional stability against water and heat, but acetate film, polyvinyl chloride film, etc. , borisbrene film, polypropylene film, polyethylene film may also be used.

After passing at a rate of 0 CI/min, the support was peeled off. Peeling was easy and only the black image area was transferred onto the art paper.

Subsequently, colored images were transferred in the order of cyan, magenta, and yellow, thereby obtaining a color bluefing image consisting of four colors on art paper.

In this example as well, only the image portion was transferred, and the finished product was very similar to the actual printed matter.

0.4 g of the obtained coating solution was mixed into a polyethylene teleph clay p film (12.
5 μm). A transparent polypropylene copper film having a thickness of 19 μm was then laminated thereon.

To remove the four-color image, this photopolymerizable film is used as an image-receiving material (KroIllckotc).
The cover film was removed and laminated on top of the film. This is then passed through a screen gradation and a cyan color separation positive with sufficient area to
Exposure was carried out for 42 seconds at a distance of 95 cm in a vacuum chamber using a 0W metal halide lamp and a UV filter (Kokoso Fino Letter).

The polyethylene terephthalate film was then removed and a conventional cyan toner applied to the exposed side in an automatic toning machine. This toner remains attached only to the unexposed sticky areas of the film. A second layer of photopolymerizable film is laminated onto the surface of this colored abrasive material, and through the corresponding magenta color separation,
It was exposed for 47 seconds as before and colored with a conventional magenta toner. Yellow (exposure time 47 seconds)
, and black < n light time 60 seconds), the corresponding operating steps were repeated. A protective film for the color after R was applied. For this purpose, a photopolymerized film was further laminated, exposed to light and the film was stripped off.

The resulting color proof was entirely covered with a polymer film, so it looked like a photograph and did not resemble a printed matter. At least matting is necessary to approximate printed matter.

However, even when the image is matted, the contrast of the image decreases and the approximation to printed matter is insufficient.

[Effects of the Invention] As explained in detail above, according to the present invention, by providing a release layer on the support that can be washed off during development, only the colored image area can be directly transferred to the transfer material. It is possible to obtain a transferred image that closely approximates the image quality of the printed matter.

Furthermore, since accurate image reproduction can be achieved through extremely simple processes such as @-like exposure, development, and transfer, it is particularly suitable as a color proof for color proofing.
