Heat developable color photosensitive material

Abstract

Abstract PURPOSE:To inhibit the fogging of a photosensitive material and a change in the maximum density during the storage of the material before heat development by adding photosensitive silver halide, a hydrophilic binder, a reducing dye-providing substance, and a heat meltable substance with >=60 deg.C m.p. to a layer to be formed on a support. CONSTITUTION:To a layer to be formed on a support are added photosensitive silver halide, a hydrophilic binder, a reducing dye-providing substance, and a heat meltable substance with >=60 deg.C m.p. represented by formula I , II or III, wherein each of (m), (q) and (s) is 1-3, (n) is 1-8, (p) is a number satisfying p+q=6, (r) is a number satisfying r+s=8, R is H, alkyl, cycloalkyl or other substituent, R1 is an org. group forming alcohol, phenol or naphthol as R1-(OH)n, saccharide may be formed, and R2 is an org. group forming alcohol, phenol or naphthol as R2-OH.
