摘要:
A photosensitive material comprising (A) a flexible transparent film support, (B) a colored photosensitive layer which contains an organic binder (B1) a dye or a colored pigment (B2), a compound (B3), which forms a strong acid on exposure to radiation, and a compound (B4) which has at least one group cleavable by the acid, and (C) an adhesion-promoting layer which contains a thermoplastic polymer which has a softening temperature in the range from 40.degree. to 200.degree. C., wherein the adhesion (a.sub.1) of the unexposed photosensitive layer (B) to the adhesion-promoting layer (C) is less than the adhesion (a.sub.3) of the unexposed photosensitive layer (B) to the film support (A) and than the cohesions of the layers (B) and (C), and the adhesion (a.sub.3 ') of the exposed photosensitive layer (B) to the film support (A) is less than the adhesion (a.sub.1 ') of the exposed photosensitive layer (B) to the adhesion-promoting layer (C) and than the cohesions of the adhesion-promoting layer (C) and of the exposed photosensitive layer (B) is useful for the production of a colored image, in particular, is useful in a color proofing method for multicolor printing, which process gives images having high resolution.
