PURPOSE:To obtain a bright color image with a simple method by migrating the movable hydrophilic dyes released by heating to a dye fixed layer in the stage of contg. substantially no water. CONSTITUTION:A photosensitive material have the two binder layers, adjacent to each other, contg. photosensitive silver halide and/or dye donative materials which exhibit a reducing property with photosensitive silver halide and release hydrophilic dyes by reacting with the photosensitive silver halide when heated, on a base. The photosensitive material in which the molar amt. of the dye donative material coated on he binder layer A on the side where the light for exposing comes in of the two binder layers is smaller than that of the other binder layer B is heated in the stage of contg. substantially no water simultaneously or after the exposing to form the movable dyes like an image. The photosensitive silver halide is contained in either layer in the above-described binder layer group and a satisfactory result is obtd. if the ratio between the amt. of the silver coated on the binder layer A/that on the binder layer B is larger than 1/10. |
