PURPOSE:To obtain clear dye image by providing a photosensitive layer comprising silver halide, a reducing agent, a polymerizable compd. and a specific leuco dye on a substrate. CONSTITUTION:The titled material is provided with the photosensitive layer comprising the silver halide, the reducing agent, the polymerizable compd. and the leuco dye (a cyan image forming substance) shown by formula I on the substrate. In formula I, R<1> and R<2> are each hydrogen atom, alkyl or cycloalkyl group, etc., X is hydrogen, or halogen atom, or alkyl group, etc., Y is alkyl or aralkyl group, Z is hydrogen atom, alkyl or aryl group. Thus, the image having a high max. density and a low min. density, namely, a high S/N is obtd. Accordingly, in case that the image is formed by using said photosensitive material, the clear dye image can be obtd. |
