PURPOSE:To prevent fading of an org. coloring material to light by allowing the org. coloring material and specific compd. to co-exist. CONSTITUTION:The org. coloring material and the compd. expressed by formula I are made to co-exist. In formula I, R denotes an 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 aryloxycarbonyl group; X denotes an oxygen atom. or -N(R<1>)- group; R<1> denotes a hydrogen atom. or group similar to R; Z1 and Z2 respectively denote an alkylene group of 1-3C (where the total sum of carbon atoms. of Z1 and Z2 is 3-6); (n) denotes 1 or 2 integer. The discoloration and fading of the org. coloring material, more particularly, the coloring matter dye, etc., used for color photographic sensitive material are thereby greatly decreased. |
