Silver halide photographic light-sensitive material

Claim 1

A silver halide photographic light-sensitive material comprising a support, having provided on a single side thereof, a silver halide emulsion layer and a hydrophilic colloid layer, wherein said silver halide emulsion layer contains a hydrazine derivative, represented by Formula (A) or Formula (B), and at least one of said silver halide emulsion layer and said hydrophilic colloid layer contains a latex comprising polymer particles formed by polymerization in the presence of gelatin; ##STR23## wherein A is aryl or a heterocyclic containing a sulfur atom or an oxygen atom; n is an integer of 1 or 2; when n is 1, R 1 and R 2 are each hydrogen, alkyl, alkenyl, alkynyl, aryl, heterocyclic, hydroxy, alkoxy, alkenyloxy, alkynyloxy, aryloxy, or heterocycloxy, R 1 may be linked together with R 2 to form a ring including the nitrogen atom; when n is 2, R 1 and R 2 are each hydrogen, alkyl, alkenyl, alkynyl, aryl, a saturated or unsaturated heterocyclic, hydroxy, alkoxy, alkenyloxy, alkynyloxy, aryloxy, or heterocycloxy, provided that at least one of R 1 and R 2 is alkenyl, alkynyl, saturated heterocyclic, hydroxy, alkoxy, alkenyloxy, alkynyl, aryloxy, or heterocycloxy; R 3 is alkynyl or a saturated heterocyclic; A 1 ' and A 2 ' are each hydrogen or either one of them is hydrogen and the other is substituted or unsubstituted alkylsulfonyl, substituted or unsubstituted acyl, or substituted or unsubstituted oxalyl.
