Abstract
Abstract A color photographic silver halide light-sensitive material is described containing a colorless photographic cyan color-forming coupler having, in a position for coupling with the oxidation product of an aromatic primary amine developing agent, as a coupling-off group, at least one alkoxy group substituted with a sulfinyl group represented by the formula (I) -O-R-SO-R.sub.1 (I) wherein R represents a saturated or unsaturated, divalent aliphatic group which may be straight or branched chain and may be substituted; and R 1 represents a substituted or unsubstituted straight or branched chain alkyl group, an alkenyl group, an aralkyl group, an aralkenyl group, a cycloalkyl group, an aryl group or a heterocyclic group; and said heterocyclic group being connected with a sulfinyl group on the position of a carbon atom of the heterocyclic group.
