Document Type and Number:
Japanese Patent JPH077191
Kind Code:
B2
Abstract:
A light-sensitive silver halide photographic material comprising: a compound of formula [I], wherein: Z is a non-metallic group which, together with the nitrogen and carbon atoms to which it is attached, forms a nitrogen-containing heterocyclic ring; X is hydrogen or a substituent capable of being split off upon reaction with an oxidation product of a color developing agent; and R is hydrogen or a substituent; at least one compound of formula [XII], wherein: R<1> is an aliphatic group, a cycloalkyl group, an aryl group or a heterocyclic group; and Y<1> is a non-metallic group which, together with the nitrogen to which it is attached, forms a morpholine or thiomorpholine ring; and at least one compound of formula [XIIIa] or (XIIIb), wherein: R<2> and R<5>, which may be identical or different, are each hydrogen, a halogen, an alkyl group, an alkenyl group, an alkoxy group, an alkenyloxy group, a hydroxyl group, an aryl group, an aryloxy group, an acyl group, an acylamino group, an acyloxy group, a sulfonamide group, a cycloalkyl group or an alkoxycarbonyl group; R<3> is hydrogen, an alkyl group, an alkenyl group, an aryl group, an acyl group, a cycloalkyl group or a heterocyclic group; R<4> is hydrogen, a halogen, an alkyl group, an alkenyl group, an aryl group, an aryloxy group, an acyl group, an acylamino group, an acyloxy group, a sulfonamide group, a cycloalkyl group or an alkoxycarbonyl group; or R<3> and R<4> may, together with the oxygen and carbon atoms to which they are attached and the carbon atom to which these atoms are attched, form a 5- or 6-membered ring; and Y<2> is a group which, together with the oxygen and carbon atoms to which it is attached and the carbon atom to which these atoms are attached, forms a chroman or coumaran ring; wherein: R<1><2> and R<1><4>, which may be identical or different, are each hydrogen, a halogen, an alkyl group, an alkenyl group, an alkoxy group, a hydroxyl group, an aryl group, an aryloxy group, an acyl group, an acylamino group, an acyloxy group, a sulfonamide group, a cycloalkyl group or an alkoxycarbonyl group;
