Color photographic materials containing dye-fading inhibitors

Abstract

Abstract The present invention is directed to a color photographic material which is characterized as containing a compound represented by the following formula I in combination with a compound represented by the following formula II ##STR1## wherein R represents an alkyl group, an alkenyl group, a cycloalkyl group, an aryl group or a heterocyclic ring; R 1 , R 2 and R 3 individually represent hydrogen, halogen, an alkyl group, an alkylthio group, an alkoxy group, an aryl group, an aryloxy group, an arylthio group, an acyl group, an acylamino group, a diacylamino group, an acyloxy group, a sulfonamido group, an alkylamino group, a cycloalkyl group or an alkoxycarbonyl group; and Z represents an atomic group or groups necessary for forming a chroman or coumaran ring; provided that R and R 1 can cooperatively be cyclized to form a chroman or cumaran ring. ##STR2## wherein A 1 , A 2 , A 3 and A 4 are individually alkyl having 1-18 carbon atoms, the total number of carbon atoms of A 1 , A 2 , A 3 and A 4 being not more than 32; and X is a simple bond, oxygen, sulfur, sulfonyl or ##STR3## in which A 5 is hydrogen or alkyl having 1-10 carbon atoms and n is an integer of 1-3.
