Abstract
Abstract A light-sensitive material comprising a light-sensitive layer containing silver halide, a reducing agent, a polymerizable compound and a leuco dye provided on a support, characterized in that the leuco dye is a compound having the following formula (I): ##STR1## in which A is --O--or ##STR2## and R is a substituent having a positive substituent constant (σ); each of R 1 and R 2 is an alkyl group, a cycloalkyl group or an aralkyl group; each of R 3 , R 4 and R 5 is an alkyl group, an alkoxy group, a cycloalkyl group, an aralkyl group or an aryloxy group; each of k, l and n is 1 or 2; and m is 0, 1 or 2.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
A light-sensitive material comprising a light-sensitive layer containing silver halide, a reducing agent, an ethylenic unsaturated polymerizable compound and a leuco dye provided on a support, wherein the leuco dye is a compound having the following formula (II): ##STR15## in which R 1 and R 2 are the same groups selected from the group consisting of an alkyl group and a cycloalkyl group; R 3 and R 4 are the same groups selected from the group consisting of an alkyl group, a cycloalkyl group and an alkoxy group; and the sum of carbon atoms contained in the groups of R 1 and R 3 is not less than 5.
Claim 2
Dependent Claim
109 words
A light-sensitive material comprising a light-sensitive layer containing silver halide, a reducing agent, an ethylenic unsaturated polymerizable compound and a leuco dye provided on a support, wherein the leuco dye is a compound having the following formula (II): ##STR15## in which R 1 and R 2 are the same groups selected from the group consisting of an alkyl group and a cycloalkyl group; R 3 and R 4 are the same groups selected from the group consisting of an alkyl group, a cycloalkyl group and an alkoxy group; and the sum of carbon atoms contained in the groups of R 1 and R 3 is not less than 5.
Claim 3
Dependent Claim
18 words
The light-sensitive material as claimed in claim 1, wherein the leuco dye is dissolved in the polymerizable compound.
Claim 4
Dependent Claim
36 words
The light-sensitive material as claimed in claim 1, wherein the polymerizable compound and the leuco dye are contained in microcapsules which are dispersed in the light-sensitive layer, said leuco dye being dissolved in the polymerizable compound.
Claim 5
Dependent Claim
39 words
The light-sensitive material as claimed in claim 1, wherein the silver halide, the polymerizable compound and the leuco dye are contained in microcapsules which are dispersed in the light-sensitive layer, said leuco dye being dissolved in the polymerizable compound.
Claim 6
Dependent Claim
39 words
The light-sensitive material as claimed in claim 1, wherein the reducing agent, the polymerizable compound and the leuco dye are contained in microcapsules which are dispersed in the light-sensitive layer, said leuco dye being dissolved in the polymerizable compound.
Claim 7
Dependent Claim
36 words
The light-sensitive material as claimed in claim 1, wherein the leuco dye is contained in an amount of from 0.5 to 50 weight % based on the amount of the polymerizable compound in the light-sensitive layer.
