An intensification processing in photographic processing for color photographic elements is effectively performed with less formation of fog by incorporating in at least one of the silver halide emulsion layers or in an auxiliary layer adjacent to a silver halide emulsion layer one or more compounds of the general formula--(A).sub.x -- (B).sub.y --wherein A represents ##STR1## (wherein R represents ##STR2## or --OH; m represents an integer of 3 to 7; R.sub.1 represents an alkyl group of 1 to 6 carbon atoms; and R.sub.2 represents a hydrogen atom or an alkyl group of 1 to 4 carbon atoms; B represents a monomer unit from styrene, methacrylic acid ester, an acrylic acid ester, vinyl acetate, acrylonitrile, vinyl alcohol, vinyl chloride, vinyl ether, acrylamide, N,N-dimethylacrylamide, acrylic acid, methacrylic acid, maleic acid, potassium styrene sulfonate, an N,N-dialkylaminoalkyl methacrylate, vinyl imidazole, or vinyl pyridine; and x and y represent mole percent, the sum of x and y being 100 mole percent and x being 30 mole percent or higher.
