Abstract: A color photographic material, at least one layer of which contains a compound of the formula (I) ##STR1## in which X means --NH--, --NR-- or --O--,R means alkyl, cycloalkyl or aryl,R.sub.1 means a chemical bond or a divalent bridging member,R.sub.2 and R.sub.3 mean alkyl, alkoxy, alkenyl, cycloalkyl, aryl or aryloxy, or two residues R.sub.2 or R.sub.3 mean the remaining atoms of a benzene ring condensed with the phenyl residue andm and n mean 0 to 3, wherein all alkyl, alkoxy, cycloalkyl, alkenyl, aryl and aryloxy residues may be further substituted and in each of the two phenyl residues a residue R.sub.1, R.sub.2 or R.sub.3 is in para position relative to the oxygen atom, is characterized by improved dye stability after processing.

Abstract: A color photographic material with at least one silver halide emulsion layer which contains a color coupler distributed in a polymeric oil former and at least one compound of the formula (I) ##STR1## in which R means alkyl, cycloalkyl, alkenyl, aryl, acyl, alkylsulphonyl or arylsulphonyl,R.sub.1 means a chemical bond or a divalent bridging member,R.sub.2 and R.sub.3 mean alkyl, alkoxy, alkenyl, cycloalkyl, aryl or aryloxy or two residues R.sub.2 or R.sub.3 the remaining atoms of a benzene ring condensed with the phenyl residue andm and n mean 0 to 3, wherein all alkyl, alkoxy, cycloalkyl, alkenyl, aryl, aryloxy and acyl residues may be further substituted,is characterized by improved color stability.

Abstract: A color photographic recording material with at least one silver halide emulsion layer and a color coupler associated with that layer, which contains in the silver halide emulsion layer or in an adjacent non-photosensitive binder layer a combination of a color coupler and a compound corresponding to general formula (I) or (II): ##STR1## in which R.sub.4 is the residue of a polymer produced by polycondensation andR.sub.1 to R.sub.3, m and n are as defined in the specification, ##STR2## in which R.sub.4 is as defined above and L.sub.1, L.sub.2, X, R.sub.5 to R.sub.11, p, q and r are as defined in the specification,is distinguished by improved stability of the image dyes produced from yellow couplers.

Abstract: A color photographic material which contains in at least one blue-sensitive layer a yellow coupler and a compound of the formula (I) ##STR1## in which R.sub.1 means hydrogen or alkyl,R.sub.2 means hydrogen or alkyl,R.sub.3 means hydrogen or alkyl,1 means 1 to 20X ##STR2## or cycloalkene, R.sub.4 means hydrogen or alkyl,R.sub.5 means hydrogen or alkyl andn means 1 to 6,shows improved light-stability of the yellow dye obtained from said yellow coupler by exposure and processing.
