Abstract
Abstract A process for preparing a color proofing sheet is disclosed. The process comprises imagewise exposing a light-sensitive image-forming material comprising a transparent support having provided thereon a dye- or pigment-containing light-sensitive photoresist composition layer or both a dye- or pigment-containing colorant layer and a light-sensitive photoresist composition layer through a color separation mask, developing the material to form a color separation image, transferring the color separation image onto a photopolymerizable image-receiving layer, transferring in registration at least one more color separation image onto the same image-receiving layer to obtain a multicolored color proofing sheet on a single support, and totally exposing the image-receiving layer after the image transfer in an amount sufficient to induce photopolymerization thereof. A color proofing sheet realizing color reproduction essentially the same as actual print copies and has a good image strength and non-tackiness can be obtained by the process.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A process for preparing a color proofing sheet, which comprises imagewise exposing a light-sensitive image-forming material comprising a transparent support having provided thereon a dye- or pigment-containing light-sensitive photoresist composition layer or both a dye- or pigment-containing colorant layer and a light-sensitive photoresist composition layer through a color separation mask, developing the material to form a color separation image, transferring the color separation image onto a photopolymerizable image-receiving layer, transferring in registration at least one more color separation image onto the same image-receiving layer to obtain a multicolored color proofing sheet on a single support, and totally exposing the image-receiving layer after the image transfer in an amount sufficient to induce photopolymerization thereof.
Claim 2
Dependent Claim
113 words
A process for preparing a color proofing sheet, which comprises imagewise exposing a light-sensitive image-forming material comprising a transparent support having provided thereon a dye- or pigment-containing light-sensitive photoresist composition layer or both a dye- or pigment-containing colorant layer and a light-sensitive photoresist composition layer through a color separation mask, developing the material to form a color separation image, transferring the color separation image onto a photopolymerizable image-receiving layer, transferring in registration at least one more color separation image onto the same image-receiving layer to obtain a multicolored color proofing sheet on a single support, and totally exposing the image-receiving layer after the image transfer in an amount sufficient to induce photopolymerization thereof.
Claim 3
Dependent Claim
32 words
The process of claim 1, wherein the light-sensitive image-forming material comprises the transparent support having provided thereon the dye- or pigment-containing colorant layer and the light-sensitive photoresist composition layer in that order.
Claim 4
Dependent Claim
34 words
The process of claim 1, wherein a subbing layer is provided between the support and the dye- or pigment-containing light-sensitive photoresist composition layer or between the support and the dye- or pigment-containing colorant layer.
Claim 5
Dependent Claim
13 words
The process of claim 3, wherein the subbing layer is an alcohol-soluble polyamide.
Claim 6
Dependent Claim
15 words
The process of claim 3, wherein the subbing layer remains on the support after development.
Claim 7
Dependent Claim
16 words
The process of claim 1, wherein the light-sensitive photoresist composition layer comprises a photopolymerizable light-sensitive composition.
Claim 8
Dependent Claim
14 words
The process of claim 6, wherein the light-sensitive photoresist composition layer contains an o-quinonediazide.
Claim 9
Dependent Claim
25 words
The process of claim 1, wherein the light-sensitive photoresist composition layer has a solid amount ranging of from about 1 to 5 g/m 2 .
Claim 10
Dependent Claim
19 words
The process of claim 1, wherein the dye or the pigment has a yellow, magenta, cyan or black tone.
Claim 11
Dependent Claim
38 words
The process of claim 1, wherein the image-receiving layer comprises (a) at least one polyfunctional vinyl or vinylidene compound capable of forming a polymer by addition polymerization, (b) an organic thermoplastic polymer binder and (c) a photopolymerization initiator.
Claim 12
Dependent Claim
29 words
The process of claim 10, wherein the ratio of the vinyl or vinylidene compound to the polymer binder in the image-receiving layer ranges from 0.1:1.0 to 2.0:1.0 (by weight).
Claim 13
Dependent Claim
23 words
The process of claim 10, wherein the image-receiving layer has a solid amount ranging of from about 4 to 40 g/m 2 .
Claim 14
Dependent Claim
31 words
