Summary: | PURPOSE:To improve preservability of a color photographic sensitive material in unexposed state, to improve interlayer adhesion of the photosensitive material, and to suppress the increase of the stain by dispersing a fine particles contg. a dye-liberating redox compd. and a specified polymer, into the photosensitive material. CONSTITUTION:Fine particles contg. both a fast to diffusion dye-liberating redox compd. (A) and a polymer (B) having >=1,000mol.wt. contg. >=10 times same recurrent monomer units are dispersed in a hydrophilic colloid of the title photosensitive material. A compd. consisting of a dye(precursor) residue and a redox mother nucleus (e.g. a group expressed by the formula ) is useable as the component (A). In the formula, beta is an atomic group necessary for forming a benzene ring; alpha is -OG -, -NHG (wherein G is H, a group generating an OH group; G is H, 1-22C alkyl, etc.); (b) is 0-2; 'Ball' is a fast to diffusion group. Further, poly(methyl methacrylate), etc. may be used for the component (B). |
