Abstract
A light-sensitive material having at least one emulsion layer containing silver halide grains, wherein tabular grains having an average aspect ratio of 2 or more occupy at least 50% of the total projected area of all grains, and the material contains a compound which releases two photographically useful groups from one molecule through a timing group and/or a compound which releases a photographically useful group through two timing groups.
Claims12
A silver halide color photographic light-sensitive material comprising a support and thereon at least one light-sensitive emulsion layer containing a silver halide emulsion comprising tabular grains having an average aspect ratio of 2 or more, and at least one of the emulsion layers contains a compound represented by the formula (III), or (IV):
- ##STR26## wherein A represents a coupler residue or a redox group;
- INH is a developer inhibitor group;
- R.sub.101 and R.sub.102 each independently represents a hydrogen, an aryl group, an alkyl group, a halogen atom, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, an amino group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an acylamino group, a sulfonamido group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, an ureido group, a cyano group, or a nitro group and in formula (III) does not contain an INH group;
- R.sub.103 and R.sub.104 each independently has the same meaning as R.sub.101 and R.sub.102 ;
- R.sub.105 represents an unsubstituted phenyl group, an unsubstituted primary alkyl group, a primary alkyl group substituted with a halogen atom, an alkoxy group, an alkylthio group, an amino group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group, an acylamino group, a sulfonamido group, an alkoxycarbonylamino group, an ureido group, a cyano group, or a nitro group or a group represented by --CO.sub.2 CH.sub.2 CO.sub.2 R.sub.106 wherein R.sub.106 is an unsubstituted alkyl group having 3 to 6 carbon atoms;
- R.sub.111, R.sub.112 and R.sub.113 each independently represents a hydrogen atom, an alkyl group, or an aryl group;
- wherein at least one of R.sub.101 to R.sub.104 is other than a hydrogen atom and any two of R.sub.111, R.sub.112 and R.sub.113 can be divalent groups which bond together to form a ring.
