Abstract
Abstract A silver halide photographic light-sensitive material is disclosed. The material comprises a light-sensitive silver halide emulsion layer and containing both of a latex stabilized by gelatin and a redox compound from which a development inhibitor is released when the redox is oxidized in the emulsion layer or other non-light-sensitive hydrophilic colloidal layer. The silver halide photographic light-sensitive material is suitable for graphic arts plate-making use and is excellent in Ming-Gothic type reproduction, screen-image enlarging and screen-image reduction aptitudes, white-on-color letter quality, paste-up trace prevention, easy handling and stability.

Claim 1
Independent Claim
59 words
A silver halide photographic light-sensitive material comprising a support and a light-sensitive silver halide emulsion layer wherein said silver halide photographic light-sensitive material comprising a latex prepared in the presence of added gelatin during or after polymerization of the latex and a redox compound from which a development inhibitor is released when said redox is oxidized during developing process.
Claim 2
Dependent Claim
59 words
A silver halide photographic light-sensitive material comprising a support and a light-sensitive silver halide emulsion layer wherein said silver halide photographic light-sensitive material comprising a latex prepared in the presence of added gelatin during or after polymerization of the latex and a redox compound from which a development inhibitor is released when said redox is oxidized during developing process.
Claim 3
Dependent Claim
125 words
A silver halide photographic light-sensitive material of claim 1, wherein the silver halide photographic light-sensitive material comprises a hydrazine compound of Formula (H). ##STR41## wherein A represents an aryl group or a heterocyclic group containing at least one sulfur or oxygen atom; G represents -(CO) n - group, a sulfonyl group, a sulfoxy group, ##STR42## group or an iminomethylene group; n is an integer of 1 or 2; A 1 and A 2 represent each a hydrogen atom or a hydrogen atom for one and a substituted or unsubstituted alkylsulfonyl or acyl group for the other; R represents a hydrogen atom, or an alkyl, aryl, alkoxy, aryloxy, amino, carbamoyl, oxycarbonyl or -O-R 4 group in which R 4 represents an alkyl or saturated heterocyclic group.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
53 words
A silver halide photographic light-sensitive material comprising a support having thereon a light-sensitive silver halide emulsion layer containing a latex prepared in presence of gelatin during or after synthesizing the latex, a non-light sensitive hydrophilic layer containing a redox compound from which a development inhibitor is released when said redox compound is oxidized.
Claim 6
Dependent Claim
