摘要:
A color light-sensitive material comprising at least light-sensitive silver halide, a binder, a reducible dye providing compound and a reducing agent represented by the following formula (I). ##STR1## wherein R.sup.1 and R.sup.2 each represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an acylamino group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, an acyl group, a sulfonyl group, a carbamoyl group or a sulfamoyl group, or R.sup.1 and R.sup.2 may be combined together to form a carbon ring or a heterocyclic ring; R.sup.3 represents an alkylene group; R.sup.4, R.sup.5, R.sup.6 and R.sup.7 each represents a hydrogen atom, a halogen atom, a hydroxyl group, a cyano group, a nitro group, an alkyl group, an acylamino group, a sulfonamido group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, an amino group, an acyl group, an acyloxy group, a carbamoyl group, a carbamoylamino group, a sulfamoyl group, a sulfamoylamino group, an alkoxycarbonyl group, an aryloxycarbonyl group, a heterocyclic group, an aryloxycarbonyloxy group, an alkoxysulfonyl group or an aryloxysulfonyl group (with the proviso that R.sup.5 is not a hydroxyl group), or two adjoining groups may be combined together to form a carbon ring or a heterocyclic ring; X represents --NHCO--, --NHCONH--, --CONH--, --NHSO.sub.2 --, --NHSO.sub.2 NH-- --SO.sub.2 NH-- or ##STR2## m and n each represents 0 or 1; and the sum total of carbon atoms of R.sup.1 to R.sup.7 is not less than 8.
