Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 85 words
A light-sensitive material comprising a light-sensitive layer containing silver halide, a reducing agent and an ethylenically unsaturated polymerizable compound provided on a support, said silver halide and polymerizable compound being contained in microcapsules which are dispersed in the light-sensitive layer, wherein the light-sensitive layer further contains a white pigment which is arranged outside of the microcapsules, said white pigment being contained in an amount in the range of 5 weight % to 50 weight % based on the total solid content of the light-sensitive layer.
Claim 2
Dependent Claim 85 words
A light-sensitive material comprising a light-sensitive layer containing silver halide, a reducing agent and an ethylenically unsaturated polymerizable compound provided on a support, said silver halide and polymerizable compound being contained in microcapsules which are dispersed in the light-sensitive layer, wherein the light-sensitive layer further contains a white pigment which is arranged outside of the microcapsules, said white pigment being contained in an amount in the range of 5 weight % to 50 weight % based on the total solid content of the light-sensitive layer.
Claim 3
Dependent Claim 32 words
The light-sensitive material as claimed in claim 1, wherein the white pigment is a compound selected from the group consisting of titanium dioxide, barium sulfate, zinc oxide, calcium carbonate and zinc sulfide.
Claim 4
Dependent Claim 18 words
The light-sensitive material as claimed in claim 1, wherein the white pigment is titanium dioxide or zinc oxide.
Claim 5
Dependent Claim 34 words
The light-sensitive material as claimed in claim 1, wherein the microcapsules are arranged in contact with each other and the white pigment is placed within a space formed by microcapsules adjoining to each other.
Claim 6
Dependent Claim 36 words
The light-sensitive material as claimed in claim 1, wherein the white pigment is in the form of particles having an average diameter of not larger than one fifth part of the average diameter of the microcapsules.
Claim 7
Dependent Claim 28 words
The light-sensitive material as claimed in claim 1, wherein the white pigment is in the form of particles having an average diameter of from 0.05 to 5 μm.
Claim 8
Dependent Claim 17 words
The light-sensitive material as claimed in claim 1, wherein the reducing agent is contained in the microcapsules.
Claim 9
Dependent Claim 30 words
The light-sensitive material as claimed in claim 1, wherein the light-sensitive layer further contains a color image forming substance and the color image forming substance is contained in the microcapsules.
Claim 10
Dependent Claim 34 words
The light-sensitive material as claimed in claim 1, wherein the polymerizable compound is contained in an amount of 5 to 1.2×10 5 times by weight as much as the amount of the silver halide.
Claim 11
Dependent Claim 21 words
The light-sensitive material as claimed in claim 1, wherein the silver halide is arranged in the shell material of the microcapsules.
