ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer is described, the color photographic light-sensitive material containing a coupler having at the coupling position thereof a group represented by formula (I) ##STR1## wherein Z represents an oxygen atom or a sulfur atom; R.sub.1 and R.sub.2 each represents a halogen atom, an alkyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, a cyano group, a nitro group, a hydroxy group, a carboxy group, an alkoxycarbonyl group, an aryloxycarbonyl group, an alkylsulfonamido group, an arylsulfonamido group, an alkylsulfamoyl group, an arylsulfamoyl group, an acylamino group, an amino group, an alkylcarbamoyl group, an arylcarbamoyl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylcarbonyl group or an arylcarbonyl group; X.sub.1 represents a divalent organic connecting group; l is 0 or 1; and n and m each is 0, 1, 2, 3 or 4 and the total number of n+m is 1 to 8, when n or m represents 2 or more the R.sub.1 or R.sub.2 groups may be the same or different.
The silver halide color photographic light-sensitive material containing the 2-equivalent coupler having a group capable of being released upon a coupling reaction represented by formula (I) has excellent color forming properties even when it is processed in a color developing solution which does not contain an organic solvent for accelerating color formation, such as benzyl alcohol. A method of forming a color image using the silver halide color photographic light-sensitive material is also disclosed.
