PURPOSE:To reduce the light fading properties of a color matter and a dye etc., which are used for the org. coloring substance, and especially, a color photographic sensitive material by incorporating a specified light fading inhibitor together with the org. coloring substance in a photosensitive material. CONSTITUTION:The photosensitive material contains the org. coloring substance and at least one kind of the compd. shown by formula I, wherein R<1> is hydrogen atom, alkyl, alkenyl, cycloalkyl, aryl, acyl, sulfonyl or a heterocyclic group, R<2> is a substituting group, (n) is an integer of 0-6. When (n) is an integer of >=2, plural groups of R<2> may be the same or the different with each other. X is a single bond or a methylene group. Thus, the stability of the org. coloring substance against the light is improved, and the light fading of the org. coloring substance is prevented. |
