Abstract
A silver halide photographic light-sensitive material which is excellent in raw-stock preservability, physical characteristics of its layers such as glossiness, scratch resistance, and degree of swelling and whose sensitivity changes very little with time after manufacture comprising a compound represented by Formula [I] of the specification, hardened with at least one of the compounds represented by Formula [II] or [III] of the specification. The storage stability is further improved when at least one of the cyan couplers represented by Formula [IX] or [X] of the specification is present.
Claims16
A silver halide photographic light-sensitive material comprising,
- a layer containing a compound represented by the following Formula (I), said layer being hardened with at least one of the compounds represented by the Formula (II) or (III), and
- a silver halide photographic emulsion layer containing at least one of the cyan couplers represented by the Formula (IX) or (X);
- ##STR43## wherein R.sub.1, R.sub.2 and R.sub.3 each represents hydrogen, a halogen, a sulfonic acid group including the salts thereof, or a monovalent organic group;
- A.sub.1, A.sub.2 and A.sub.3 each represents nitrogen or a ##STR44## in which R.sub.4 represents hydrogen, a halogen, a sulfonic acid group including the salts thereof or a monovalent organic group;
- X.sub.1 and X.sub.2 each represents a hydroxyl group or a --NR.sub.5 R.sub.6 in which R.sub.5 and R.sub.6 each represents hydrogen, an alkyl group, an aryl group or an alkylcarbonyl group, or R.sub.5 and R.sub.6 may be coupled to each other to form a ring;
- R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may also be coupled to each other to form a ring, and at least one of the groups represented by R.sub.1, R.sub.2, R.sub.3 and R.sub.4 and at least one of the groups represented by R.sub.5 and R.sub.6 may further be coupled to each other to form a ring;
- and each of n.sub.1, n.sub.2 and n.sub.3 is an integer of from 0 to 3;
- ##STR45## wherein Z.sub.1 represents chlorine, a hydroxy group, an alkyl group, an alkoxy group, an alkylthio group, a --OM group in which M represents a monovalent metal atom, or a --NR'R" group and --NHCOR"' in which R', R" and R"' each represents hydrogen, an alkyl group or an aryl group;
- and Z.sub.2 has the same definition as Z.sub.1 except it does not include chlorine;
- ##STR46## wherein Z.sub.3 and Z.sub.4 each represents chlorine, a hydroxy group, an alkyl group, an alkoxy group or a --OM group in which M represents a monovalent metal atom;
- Q and Q' each represents an --O--, --S-- or --NH-- group;
- L represents an alkylene group or an arylene group;
- and l and m each represents 0 or 1;
- ##STR47## wherein R.sub.23 represents an alkyl group or an aryl group;
- R.sub.24 represents an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group;
- R.sub.25 represents hydrogen, a halogen, an alkyl group or an alkoxy group, and R.sub.25 may be coupled to R.sub.23 to form a ring;
- and Z.sub.5 represents hydrogen or a group capable of splitting off through a reaction thereof to the oxidation products of an aromatic primary amine color developing agent;
- ##STR48## wherein R.sub.26 represents a normal or branch chained alkyl group having 1 to 4 carbon atoms;
- R.sub.27 represents a ballast group;
- Z.sub.6 has the same definition as Z.sub.5.
