1 Abstract

A photographic silver halide light-sensitive emulsion containing a cyan color forming colorless coupler having at the coupling position at which the coupler reacts with the oxidation product of an aromatic primary amine developing agent at least one alkoxy group having a sulfonyl group as a substituent and represented by the following general formula (I): -O-R-SO2-R1 (I) wherein R represents a saturated or unsaturated divalent aliphatic group having 1 to 4 carbon atoms which may be straight or branched chain and may be substituted (except those having an aryl group as a substituent on the carbon atom adjacent the oxygen atom bonded to the coupling position); and R1 represents an aliphatic group, an aromatic group or a heterocyclic group; and wherein R and R1 can combine directly or through a bonding group to form a ring and an image-forming process.
