Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
47 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 compound, a reducing agent, and a compound selected from the group consisting of a base and a base precursor, the latter compound being contained in microcapsules.
Claim 2
Dependent Claim
47 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 compound, a reducing agent, and a compound selected from the group consisting of a base and a base precursor, the latter compound being contained in microcapsules.
Claim 3
Dependent Claim
44 words
The light-sensitive material as claimed in claim 1, wherein the silver halide, the ethylenic unsaturated compound and the reducing agent are together contained in other microcapsules than the microcapsules containing the compound selected from the group consisting of a base and a base precursor.
Claim 4
Dependent Claim
32 words
The light-sensitive material as claimed in claim 1, wherein a hot-melt solvent is contained in the microcapsule containing the compound selected from the group consisting of base a base and a precursor.
Claim 5
Dependent Claim
51 words
The light-sensitive material as claimed in claim 1, wherein the shell of the microcapsule containing the compound selected from the group consisting of a base and a base precursor is composed of a thermoplastic material having a melting point or softening point in the range of 50° C. to 200° C.
Claim 6
Dependent Claim
34 words
The light-sensitive material as claimed in claim 1, wherein the shell of the microcapsule containing the compound selected from the gorup consisting of a base and a base precursor is composed of a wax.
Claim 7
Dependent Claim
19 words
The light-sensitive material as claimed in claim 1, wherein the light-sensitive layer further contains a color image forming substance.
Claim 8
Dependent Claim
60 words
The light-sensitive material as claimed in claim 1, wherein the light-sensitive layer further contains a color image forming substance, and the silver halide, the ethylene unsaturated compound, the reducing agent and the color image forming substance are together contained in other microcapsules than the microcapsules containing the compound selected from the group consisting of a base and a base precursor.
