Abstract
Abstract Disclosed are an image-receiving material comprising a support and an image-receiving layer provided thereon which contains a developer and a binder polymer mixture composed of at least two kinds of water-soluble polymers which undergo phase separation in the mixed state. This image-receiving material is advantageously employed in an image-forming method which comprises the steps of imagewise exposing to light a light-sensitive material comprising a support and a light-sensitive layer containing silver halide, a reducing agent, and an ethylenically unsaturated polymerizable compound; simultaneously or thereafter developing the light-sensitive material; and pressing the light-sensitive material on the image-receiving material to transfer the unpolymerized polymerizable compound to the image-receiving layer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
137 words
An image-forming method which comprises the steps of: imagewise exposing to light a light-sensitive material comprising a support and a light-sensitive layer provided thereon which contains silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound and a color image forming substance; simultaneously or thereafter developing the light-sensitive material; and pressing the light-sensitive material on an image-receiving material comprising a support and an image-receiving layer which comprises a developer and a binder polymer mixture composed of at least two kinds of water-soluble polymers which undergo phase separation in their mixed state, and one or both of a water-soluble zinc salt and an acid, said water-soluble zinc salt being selected from the group consisting of zinc chloride, zinc sulfate, zinc nitrate and zinc acetate to transfer the unpolymerized polymerizable compound to the image-receiving layer of the image-receiving material.
Claim 2
Dependent Claim
137 words
An image-forming method which comprises the steps of: imagewise exposing to light a light-sensitive material comprising a support and a light-sensitive layer provided thereon which contains silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound and a color image forming substance; simultaneously or thereafter developing the light-sensitive material; and pressing the light-sensitive material on an image-receiving material comprising a support and an image-receiving layer which comprises a developer and a binder polymer mixture composed of at least two kinds of water-soluble polymers which undergo phase separation in their mixed state, and one or both of a water-soluble zinc salt and an acid, said water-soluble zinc salt being selected from the group consisting of zinc chloride, zinc sulfate, zinc nitrate and zinc acetate to transfer the unpolymerized polymerizable compound to the image-receiving layer of the image-receiving material.
Claim 3
Dependent Claim
34 words
The image-forming method as claimed in claim 1, wherein at least the ethylenically unsaturated polymerizable compound and the color image forming substance of the light-sensitive layer of the light-sensitive material are contained in microcapsules.
Claim 4
Dependent Claim
17 words
The image-forming method as claimed in claim 1, wherein the developing process is carried out under heating.
Claim 5
Dependent Claim
25 words
The image-forming method as claimed in claim 1, wherein the developing process is carried out under heating at a temperature of 80° to 200° C.
Claim 6
Dependent Claim
40 words
The image-forming method as claimed in claim 1, wherein the acid is selected from the group consisting of hydrochloric acid, sulfurous acid, sulfuric acid, nitric acid, citric acid, tartaric acid, ascorbic acid, maleic acid, benzoic acid, and toluene sulfonic acid.
Claim 7
Dependent Claim
43 words
The image-forming method as claimed in claim 1, wherein one or both of the water-soluble zinc salt and the acid is contained in the image-receiving layer in an amount of 3 to 300 wt. % based on the whole amount of the binder.
