Abstract
Abstract A light-sensitive material comprises a light-sensitive layer which contains silver halide, a reducing agent, a polymerizable compound and a color image forming substance provided on a support. The silver halide, polymerizable compound and color image forming substance are contained in microcapsules to form light-sensitive microcapsules which are dispersed in the light-sensitive layer. These light-sensitive microcapsules have spectral sensitivity peaks within the wavelength region of 600 nm to 950 nm and composed of at least two kinds of light-sensitive microcapsules differing from each other with respect to spectral sensitivity.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
A light-sensitive material comprising a light-sensitive layer which contains silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound and a color image forming substance provided on a support, said silver halide, polymerizable compound and color image forming substance being contained in microcapsules to form light-sensitive microcapsules which are dispersed in the light-sensitive layer, wherein each of the light-sensitive microcapsules has the maximum spectral sensitivity peak within the wavelength region of 600 nm to 950 nm and said light-sensitive microcapsules comprise at least two kinds of light-sensitive microcapsules differing from each other with respect to spectral sensitivity, the peaks of said microcapsules being apart from each other by a wavelength of not less than 60 nm.
Claim 2
Dependent Claim
116 words
A light-sensitive material comprising a light-sensitive layer which contains silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound and a color image forming substance provided on a support, said silver halide, polymerizable compound and color image forming substance being contained in microcapsules to form light-sensitive microcapsules which are dispersed in the light-sensitive layer, wherein each of the light-sensitive microcapsules has the maximum spectral sensitivity peak within the wavelength region of 600 nm to 950 nm and said light-sensitive microcapsules comprise at least two kinds of light-sensitive microcapsules differing from each other with respect to spectral sensitivity, the peaks of said microcapsules being apart from each other by a wavelength of not less than 60 nm.
