Abstract

Abstract An image forming method is disclosed, comprising forming a latent image by imagewise exposing a recording material including a light-sensitive silver salt, a reducing agent, a polymerizable compound, and a binder, on a support, and subsequently subjecting said recording material to a substantially uniform heating at about 80° C. or more under conditions substantially not containing water, thereby forming a polymeric compound in areas where the latent image of the light-sensitive silver salt has formed.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 81 words
An image forming method which comprises forming a latent image by imagewise exposing a recording material including a light-sensitive silver salt, a reducing agent, a polymerizable compound having at least one carbon-carbon unsaturated bond, and a binder, on a suport, and subsequently subjecting said recording material to a substantially uniform heating at about 80° C. or more under conditions substantially not containing water, thereby forming a polymeric compound in areas where the latent image of the light-sensitive silver salt has formed.
Claim 2
Dependent Claim 81 words
An image forming method which comprises forming a latent image by imagewise exposing a recording material including a light-sensitive silver salt, a reducing agent, a polymerizable compound having at least one carbon-carbon unsaturated bond, and a binder, on a suport, and subsequently subjecting said recording material to a substantially uniform heating at about 80° C. or more under conditions substantially not containing water, thereby forming a polymeric compound in areas where the latent image of the light-sensitive silver salt has formed.
Claim 3
Dependent Claim 80 words
An image forming as in claim 1, wherein the light-sensitive silver salt is present in an amount of from 1 mg to 10 g/m 2 , as silver, the reducing agent is present in an amount of from 0.1 to 1,500 mol%, based on the total mols of the light-sensitive silver salt, and the polymerizable compound is present in an amount of from 5 to 120,000 wt%, based on the total weights of the silver in the light-sensitive silver salts.
Claim 4
Dependent Claim 46 words
An image forming method as in claim 1, wherein the recording material further contains a silver salt oxidizing agent, the total amount of the light-sensitive silver salt and silver salt oxidizing agent is in a range of 1 mg to 10 g/m 2 , as silver.
Claim 5
Dependent Claim 28 words
An image forming method as in claim 1, wherein the binder in the recording material is present in an amount of from 0.01 to 10 g/m 2 .
Claim 6
Dependent Claim 18 words
An image forming method as in claim 1, wherein the recording material contains a color image forming material.
Claim 7
Dependent Claim 20 words
An image forming method as in claim 5, wherein the color image forming material is a dye or a pigment.
Claim 8
Dependent Claim 41 words
