Method for improving the light fastness of color photographic dye images

摘要

A method for improving the light fastness of a magenta color image in a silver halide color photograph which comprises incorporating into a layer containing a magenta color image, which is formed upon reaction of a magenta coupler and an oxidation product of an aromatic primary amine color developing agent, at least one light fastness improving phenolic compound and at least one synergistic light fastness improving agent selected from a sulfide or sulfoxide compound represented by the following general formula (V): ##EQU1## wherein B represents --S-- or -- SO--; X and Y, which may be the same or different, each represents - -(CH. sub.2).sub.n --R.sub.1, ##STR1## or ##STR2## and R.sub.1 represents -- COOR.sub.3, ##STR3## --OR.sub.6, --O--COR.sub.6, --NHSO.sub.2 R.sub.6, ##STR4## --NHCOR.sub.6, a cyano group, an aryl group or a hydroxy group; R.sub.2 represents an alkyl group of 1 to 30 carbon atoms, an aryl group, an aralkyl group, a hydroxy group, a cyano group or --COOR.sub.3 ; R.sub. 3 R.sub.4, R.sub.5 and R.sub.6 each represents a hydrogen atom, an alkyl group of 1 to 30 carbon atoms, an aryl group, or an aralkyl group, with the proviso that R.sub.6 is not a hydrogen atom; and n is an integer of 1 to 4. A silver halide color photographic light-sensitive material which provides a magenta dye image having a good light fastness is also disclosed.
