PURPOSE:To prevent fading of an org. coloring material to light by allowing the org. coloring material and at least one kind of specific compd. to co-exist. CONSTITUTION:The org. coloring material and at least one kind of the compd. expressed by the formula are made to co-exist. In the formula, R<1> denotes a hydrogen atom., alkyl group, cycloalkyl group, alkenyl group, cycloalkenyl group, alkinyl group, aryl group, heterocyclic group, acyl group, sulfonyl group, phosphonyl group, carbamoyl group, sulfamoyl group, alkoxycarbonyl group or aryl oxycarbonyl group; R<2> denotes a substituent. (n) Denotes 0-6 integers; X denotes an oxygen atom or sulfur atom.; Y denotes a methylene group or ethylene group. The decoloration and fading of the org. coloring material, more particularly, coloring matter, dyes, etc., to be used for a color photographic sensitive material by light are thereby considerably decreased. |
