PURPOSE: To improve the light durability of a photographic dye by incorporating a specified tetrahydrothiopyrane compd. CONSTITUTION: A tetrahydrothiopyrane compd. represented by formula I is used as a stabilizer in a color photographic material optionally in combination with a phenolic antioxidant represented by formula II. In the formula I, each of R<1> and R<2> is H or methyl, each of R<3> and R<4> is H, 1-4C alkyl, etc., each of R<5> and R<6> is H, phenyl, etc., X is a divalent group completing the ring and (n) is 0-2. In the formula II, each of R<29> and R<30> is 1-12C alkyl, cyclohexyl,, etc. The compd. represented by the formula I is dissolved in a high b.p. org. solvent and contained in the photographic material in combination with a color coupler and optionally added additives. The pref. amt. of a mixture of the compds. represented by the formulae I, II is <=1g/m<2> , especially 10-300mg/m<2> .
