Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
70 words
A light-sensitive material which contains silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound or/and a cross-linkable polymer, and a base or/and a base precursor, wherein the light-sensitive material comprises a support, a polymerizable layer and a light-sensitive layer in the order, said polymerizable layer containing the ethylenically unsaturated polymerizable compound or/and the cross-linkable polymer, and said light-sensitive layer containing silver halide, and the base or/and the base precursor.
Claim 2
Dependent Claim
25 words
The light-sensitive material as claimed in claim 1, wherein the polymerizable layer further contains an acidic polymer, and the light-sensitive layer contains a hydrophilic polymer.
Claim 3
Dependent Claim
18 words
The light-sensitive material as claimed in claim 1, wherein a protective layer is provided on the light-sensitive layer.
Claim 4
Dependent Claim
26 words
The light-sensitive material as claimed in claim 3, wherein the protective layer contains a polyvinyl alcohol having a saponification degree of not less than 70 %.
Claim 5
Dependent Claim
27 words
The light-sensitive material as claimed in claim 1, wherein the light-sensitive layer further contains a polyvinyl alcohol having a saponification degree of not less than 70 %.
Claim 6
Dependent Claim
14 words
The light-sensitive material as claimed in claim 1, wherein the light-sensitive material is heat-developable.
Claim 7
Dependent Claim
15 words
The light-sensitive material as claimed in claim 1, wherein the support is an aluminum sheet.
Claim 8
Dependent Claim
32 words
The light-sensitive material as claimed in claim 1, wherein the silver halide is contained in the light-sensitive layer in a coating amount of 1 mg to 5 g/m² in terms of silver.
Claim 9
Dependent Claim
30 words
The light-sensitive material as claimed in claim 1, wherein the reducing agent is contained in an amount of 0.1 to 10 mole based on 1 mole of the silver halide.
Claim 10
Dependent Claim
34 words
The light-sensitive material as claimed in claim 1, wherein the polymerizable compound is contained in the polymerizable layer in an amount of 3 to 90 weight % based on the amount of polymerizable layer.
Claim 11
Dependent Claim
26 words
The light-sensitive material as claimed in claim 1, wherein the cross-linkable polymer is contained in the polymerizable layer in an amount of 0.1 to 7 g/m².
Claim 12
Dependent Claim
37 words
The light-sensitive material as claimed in claim 1, wherein the base or/and the base precursor is contained in the light-sensitive layer in an amount of 0.5 to 50 mole based on 1 mole of the silver halide.
Claim 13
Dependent Claim
23 words
The light-sensitive material as claimed in claim 1, wherein the polymerizable layer has a thickness in the range of 0.3 to 7 µm.
Claim 14
Dependent Claim
23 words
The light-sensitive material as claimed in claim 1, wherein the light-sensitive layer has a thickness in the range of 0.5 to 20 µm.
Claim 15
Dependent Claim
81 words
An image-forming method comprising the steps of: imagewise exposing to light a light-sensitive material according to claim 1 and simultaneously or thereafter heating the light-sensitive material at a temperature in the range of 60 to 200° C, wherein the content of water contained in the light-sensitive material is less than 10 weight % based on the total amount of the light-sensitive layer, to develop the silver halide and to imagewise harden the polymerizable compound so as to form a polymer image.
Claim 16
Dependent Claim
63 words
The image forming method as claimed in claim 15, wherein an oxidation product of the reducing agent is formed by the development of the silver halide, the oxidation product or a radical formed from the product is transferred from the light-sensitive layer to the polymerizable layer, and the polymerizable compound is imagewise hardened by the function of the oxidation product or the radical.
Claim 17
Dependent Claim
27 words
The image forming method as claimed in claim 15, wherein the light-sensitive material is heated while the surface of the light-sensitive material is open to the air.
Claim 18
Dependent Claim
27 words
The image forming method as claimed in claim 15, wherein the light-sensitive material is heated while the surface of the light-sensitive material is shielded from the air.
Claim 19
Dependent Claim
36 words
The image forming method as claimed in claim 15, wherein after the polymer image is formed the light-sensitive material is washed out with an aqueous solution to remove the light-sensitive layer and the unhardened polymerizable layer.
