In addition to the above-mentioned components, many synthetic resins are known as components for forming the coating layer, and the method for adjusting the coating bath and the coating method can be found in the photo 4S4 material manufacturing process that the present invention provides. Since this is a well-known technique in the industry, it is possible to adjust the communication f11 as appropriate. In general, the above-mentioned synthetic resin is made into a solution with water or an organic solvent, and this solution is applied onto a support by a coating method such as gieser coating, roll coating, air knife coating, or spray coating.

A suitable one is selected from the mixed bath Is) containing a medium and dissolved therein to prepare the entire coating solution.

In this way, the R'i degree is adjusted so that the coating liquid can be applied to the known coating technique for each layer from the 11th grade.

The coating solution can be applied to a transparent support by a coating method selected from among the known coating methods such as roller coating, double coating, curtain coating, roll coating, spray 'ffI coating, air knife coating, and doku knife coating. It can be applied over the body.

Regarding the effect of non-explosion, the image forming force method using one image forming material of the present invention is made as described above.
1. Image formation phase: First, the image is exposed to actinic light. As for the light source, for example, (high-pressure mercury lamp, tungsden lamp, mercury lamp, xenon lamp, CRT light source,
Various light sources such as a laser light source are used.

In the V4 layer, which is imagewise exposed to light, a crosslinking reaction occurs due to the attachment of the bar 11r, and the layer becomes insolubilized with respect to the layer.

The light irradiated surface has an adhesive value (1II after exposure because it is twisted)
If the image formation phase is immersed in water and dusted, it can be easily rubbed and rubbed lightly.
Developed by rubbing 9. At this time, the unexposed portion of the photosensitive layer and the mask layer corresponding to that portion are removed, and a positive negative film 1ItIl image is formed.
