PURPOSE: To improve stability to light without degrading hue and purity by allowing an org. coloring material and at least one kind of specific compds. to co-exist.

CONSTITUTION: The org. coloring material and at least one kind of the compds. expressed by the formula to co-exist. In the formula, R denotes a hydrogen atom, alkyl group, cycloalkyl group, alkenyl group, cycloalkenyl group, alkinyl group, aryl group, heterocyclic group, acyl group, sulfonyl group, carbamoyl group, phosphonyl group, sulfamoyl group, and oxycarbonyl group. Z denotes an alkylene group of 2W5C and the sum total of the carbon atoms of the alkylene group expressed by Z is 5W7; X denotes O or S. The org. coloring material has one absorption max. at 300W800nm in a methanol soln. The stability to light is thereby improved without degrading the hue and purity.
