Abstract
Abstract A novel color image recording method is provided, which comprises exposing to light a light-sensitive material obtained by dispersing a composition containing at least a photopolymerization initiator, a color image-forming substance and a polymerizable compound in a hydrophilic binder and then coating said dispersion on a support, subjecting said polymerizable compound in the exposed portions to polymerization, and then (a) eluting said color image-forming substance contained in the unpolymerized polymerizable compound in the unexposed portions with an alkaline aqueous solution or (b) subjecting said color image-forming substance contained in the unpolymerized polymerizable compound in the unexposed portions to chemical change so that it is discolored, thereby forming dye images.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
112 words
A color image recording method, which comprises exposing to light a light-sensitive material, which is substantially silver halide free, obtained by dispersing a composition containing at least a photopolymerization initiator, a color-image forming substance and a polymerizable compound in a hydrophilic binder and then coating said dispersion on a support, subjecting said polymerizable compound in the exposed portions to light and then (a) eluting said color image-forming substance contained in the unpolymerized polymerizable compound in the unexposed portions with an alkaline aqueous solution, or (b) subjecting said color image-forming substance contained in the unpolymerized polymerizable compound in the unexposed portions to chemical change so that it is discolored, thereby forming dye images.
Claim 2
Dependent Claim
112 words
A color image recording method, which comprises exposing to light a light-sensitive material, which is substantially silver halide free, obtained by dispersing a composition containing at least a photopolymerization initiator, a color-image forming substance and a polymerizable compound in a hydrophilic binder and then coating said dispersion on a support, subjecting said polymerizable compound in the exposed portions to light and then (a) eluting said color image-forming substance contained in the unpolymerized polymerizable compound in the unexposed portions with an alkaline aqueous solution, or (b) subjecting said color image-forming substance contained in the unpolymerized polymerizable compound in the unexposed portions to chemical change so that it is discolored, thereby forming dye images.
Claim 3
Dependent Claim
52 words
A color image recording method as claimed in claim 1, wherein said light-sensitive material comprises at least three combined elements of polymerization initiator, polymerizable compound and color image-forming substance and the spectral sensitivity of said photopolymerization initiator and the spectral absorptivity of said color image-forming substance are different between said combined elements.
Claim 4
Dependent Claim
49 words
A color image recording method as claimed in claim 2, wherein a light-sensitive composition comprising a dispersion of a polymerizable compound containing at least two or more photopolymerization initiators having different spectral sensitivities and color image-forming substances having different spectral absorptivity coated in multi-layer construction by layers is used.
Claim 5
Dependent Claim
38 words
A color image recording method as claimed in claim 3, wherein said light-sensitive composition is exposed to light having two or more different wavelengths plural times to form a multi-color image comprising two or more color image-forming substances.
Claim 6
Dependent Claim
32 words
A color image recording method as claimed in claim 3, wherein said light-sensitive composition is exposed to light through a negative color original at a shot to form a full-color positive image.
Claim 7
Dependent Claim
28 words
A color image recording method as claimed in claim 3, wherein said light-sensitive composition is exposed to light through a color mosaic mask to form a multi-color mosaic.
Claim 8
Dependent Claim

Dependent Claim
57 words
A color image recording method as claimed in claim 9, wherein in the embodiment (a) said color image-forming substance is an organic dye which contains a dissociative group having a pKa of 11 or less in the form of its precursor and undergoes reaction and/or dissociation during the washing with an alkaline aqueous solution to become water-soluble.
Claim 12
Dependent Claim
40 words
A color image recording method as claimed in claim 1, wherein in the embodiment (b) said color image-forming substance is an organic dye containing an azo group and said discoloration is effected by the reduction reaction with said processing solution.
Claim 13
Dependent Claim
28 words
A color image recording method as claimed in claim 1, wherein in the embodiment (b) a processing solution to be used contains S 2 O 4 2- ions.
