Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A light-sensitive material comprising a light-sensitive layer provided on a support wherein the light-sensitive layer contains silver halide, an ethylenic unsaturated polymerizable compound, a reducing agent, and a base or base precursor which is contained in microcapsules under the condition that the base or base precursor is dissolved or dispersed in an aqueous solution of a water retention agent.
Claim 2
Dependent Claim
59 words
A light-sensitive material comprising a light-sensitive layer provided on a support wherein the light-sensitive layer contains silver halide, an ethylenic unsaturated polymerizable compound, a reducing agent, and a base or base precursor which is contained in microcapsules under the condition that the base or base precursor is dissolved or dispersed in an aqueous solution of a water retention agent.
Claim 3
Dependent Claim
48 words
The light-sensitive material as claimed in claim 1, wherein the silver halide, the ethylenic unsaturated polymerizable compound and the reducing agent are contained together in microcapsules which are dispersed in the light-sensitive layer, and the base or base precursor is contained in microcapsules different from the above microcapsules.
Claim 4
Dependent Claim
25 words
The light-sensitive material as claimed in claim 1, wherein the base or base precursor is dissolved in an aqueous solution of the water retention agent.
Claim 5
Dependent Claim
44 words
The light-sensitive material as claimed in claim 1, wherein the water retention agent is a water soluble polymer having a functional group in the molecule which is selected from the group consisting of hydroxyl group, carboxylic acid group, carboxylate group and acid amide group.
Claim 6
Dependent Claim
30 words
The light-sensitive material as claimed in claim 1, wherein the water retention agent is a polyol selected from the group consisting of glycerol, diethylene glycol, triethylene glycol and propylene glycol.
Claim 7
Dependent Claim
40 words
The light-sensitive material as claimed in claim 1, wherein the shells of the microcapsules containing the base or base precursor comprise a thermoplastic material having a melting point or softening point in the range of 50° C. to 200° C.
Claim 8
Dependent Claim
23 words
The light-sensitive material as claimed in claim 1, wherein the shells of the microcapsules containing the base or base precursor comprise a wax.
Claim 9
Dependent Claim
25 words
The light-sensitive material as claimed in claim 1, wherein the shells of the microcapsules containing the base or base precursor comprise polyurea and/or polyurethane resin.
Claim 10
Dependent Claim
18 words
The light-sensitive material as claimed in claim 1, wherein the light-sensitive layer contains a color image forming substance.
