Abstract
Abstract A light-sensitive material comprises a light-sensitive layer containing a light-sensitive silver halide, a reducing agent and a polymerizable compound having an ethylenic unsaturated group which is provided on a support. The light-sensitive layer contains a polymer binder having an ethylenic unsaturated double bonding group in its side chain. The light-sensitive material is advantageously employable as a lithographic plate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
A light-sensitive material comprising a light-sensitive layer containing a light-sensitive silver halide, a reducing agent and a polymerizable compound having an ethylenic unsaturated group provided on a support, wherein the light-sensitive layer contains a polymer binder having an ethylenic unsaturated double bonding group in its side chain, wherein said polymer binder comprises at least one copolymer derived from a first monomer selected from the group consisting of allyl acrylate, allyl methacrylate, vinyl acrylate and vinyl methacrylate and a second monomer copolymerizable with the first monomer.
Claim 2
Dependent Claim
85 words
A light-sensitive material comprising a light-sensitive layer containing a light-sensitive silver halide, a reducing agent and a polymerizable compound having an ethylenic unsaturated group provided on a support, wherein the light-sensitive layer contains a polymer binder having an ethylenic unsaturated double bonding group in its side chain, wherein said polymer binder comprises at least one copolymer derived from a first monomer selected from the group consisting of allyl acrylate, allyl methacrylate, vinyl acrylate and vinyl methacrylate and a second monomer copolymerizable with the first monomer.
Claim 3
Dependent Claim
37 words
The light-sensitive material as claimed in claim 1, wherein the light-sensitive layer contains the polymer binder in an amount of 5 to 70 weight % based on the total amount of materials constituting in the light-sensitive layer.
Claim 4
Dependent Claim
24 words
