Abstract

Silver halide color light-sensitive materials which contain a compound having a repeating unit represented by general formula (I) and a compound represented by general formula (II): ##STR1## wherein R.sub.1 represents --OR, --SR or wherein R and R' each represents a hydrogen atom, or alkyl group, a hydroxyalkyl group, a sulfoalkyl group (or a salt thereof), a carboxyalkyl group (for a salt thereof), an aralkyl group, an aryl group, or a cycloalkyl group, or R and R' may form an alkylene group or an --O-- containing alkylene ring together; R.sub.2, R.sub.3, R.sub.4 and R.sub.5 each represents a hydrogen atom or an alkyl group; Y.sub.1, Y.sub.2, Y.sub.3 and Y.sub.4 each represents a polymethylene group, an arylene group, or a cycloalkylene group, Z represents --O--, --SO.sub.2 -- or --CH.sub.2 --; and l and m each represents 0 or 1; ##STR2## wherein R.sub.6 represents a hydrogen atom, an alkyl group; R.sub.7 and R.sub.8, which may be identical or different, each represents an alkyl group, or an aryl group, but at least one of R.sub.7 and R.sub.8 is an alkyl group having an acid substituent; D and E, which may be identical or different, each represents a hydrogen atom, a halogen atom, an alkyl group, a hydroxyl grup, an alkoxy group, an acyl group, an acyloxy group, an alkoxycarbonyl group, a carbamoyl group, a sulfamoyl group, a cyano group, a carboxyl group, an sulfo group, a trifluoromethyl group, a phenyl group or a benzene condensed ring, but at least one of D and E represents a hydroxyl group, an alkoxy group, an alkoxycarbonyl group or a carboxyl group; Z.sub.1 represents an anion; and n represents 1 or 2, but n represents 1 when the dye forms an inner salt; the light-sensitive materials improve sensitization processing aptitude.
