Abstract

PURPOSE:To improve the stability of the org. colored substance against a light by coexisting the org. colored substance and a specified compd. CONSTITUTION:The light fading of the org. colored substance A is prevented by coexisting said substance A and one or more kinds of the compds. shown by formula I wherein R<1> is H, alkyl or a cycloalkyl group, etc., R<2>-R<5> are each H or a substituting group. And, the substance A comprises a methine, a polymethine, an indoamine or an indophenol dyestuff, etc. The decoloration and discoloration of a color image due to the light can be reduced by incorporating the substance A and a light fading inhibitor (for example, a compd. shown by formula II) in the hydrophilic colloidal layer of a color photographic sensitive material.
