Abstract
A silver halide color light-sensitive material is disclosed which contains a compound capable of reacting with an oxidation product of a developing agent to release a photographically useful group, preferably a development inhibitor. The coupling product of the compound is dissolved into a processing solution when subjected to development processing, and, therefore, forms no substantial color image. The light-sensitive material shows improvements in sharpness, graininess, color reproducibility, and storage stability.
Claims3
A silver halide color light-sensitive material containing a compound represented by formula (IV) which releases a photographically useful group or a precursor thereof upon reaction with an oxidation product of a developing agent and which does not form a substantial color image:
- ##STR62## wherein R.sub.1 represents --CONHR.sub.13 or a group represented by formula (II):
- wherein R.sub.13 represents a a carbamoyl-, cyano-, or sulfamoyl- substituted alkyl group having not more than 4 carbon atoms excluding the carbon atoms in substituent group(s):
- ##STR63## wherein R.sub.31 represents a hydrogen atom or an alkyl group having not more than 4 carbon atoms;
- R.sub.33 represents an alkyl group having from 1 to 10 carbon atoms;
- A.sub.1 and A.sub.2 each represents CO or SO.sub.2 ;
- n.sub.4 represents 0 or 1;
- R.sub.32 represents --{C(R.sub.34)R.sub.35 }.sub.n5, wherein R.sub.34 and R.sub.35 each represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms;
- and n.sub.5 represents an integer of from 1 to 3;
- R.sub.2 represents a hydrogen atom or a substituent;
- n.sub.1 represents 0 to 4;
- the R.sub.2 groups when n.sub.1 is 2 or more may be the same or different;
- R.sub.3 is non-diffusing and represents an alkyl group, an aryl group, a heterocyclic group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, a sulfonyl group or a sulfamoyl group;
- and PUG represents a photographically useful group.
