Abstract

Abstract A method for increasing color-fastness of organic coloring matters against light is disclosed. The color-fastness of the organic coloring matter of which absorption maximum is the region from 400 nm to 700 nm is increased by coexisting with a metal complex represented by the following general formula: ##STR1## in which R 1 R 2 , R 1 ' and R 2 ' are a hydrogen atom or a substituent, X and X' are O or S, Y is O, S, SO or SO 2 and M is a metal atom. The method adapts to improve the fastness of color images of silver halide photographic materials. In this case, the organic coloring matter is a dyestuff formed by coupling a color forming coupler with an oxidation product of a color developing agent in the silver halide color photographic material or a dyestuff diffused to a receiving layer of the diffusion transfer silver halide color photographic material.
