Abstract

Abstract A process for forming an image by imagewise forming a mobile dye by heating in a substantially waterfree condition and transferring the dye into a dye fixing layer using water. The amount of water used to transfer the dye is within the range from 0.1 time the total weight of all coatings to the difference obtained by subtracting the total weight of all coatings from the weight of water corresponding to the maximum swollen volume of all coatings.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 154 words
A process for forming an image which comprises heating a light-sensitive material comprising a support having thereon at least a light-sensitive silver halide, a binder, and a dye releasing redox compound which is reductive to the light-sensitive silver halide and is capable of releasing a hydrophilic dye upon reaction with the light-sensitive silver halide by heating, after imagewise exposure or simultaneously with imagewise exposure, in a substantially water-free condition to imagewise form a mobile dye; and transferring the mobile dye into a dye fixing material using water, wherein in transferring the mobile dye, the amount of water present in all the coatings of the light-sensitive material and the dye fixing material is within a range of from 0.1 time the total weight of all the coatings to the difference obtained by subtracting the total weight of all the coatings from the weight of water corresponding to the maximum swollen volume of all the coatings.
Claim 2
Dependent Claim 154 words
A process for forming an image which comprises heating a light-sensitive material comprising a support having thereon at least a light-sensitive silver halide, a binder, and a dye releasing redox compound which is reductive to the light-sensitive silver halide and is capable of releasing a hydrophilic dye upon reaction with the light-sensitive silver halide by heating, after imagewise exposure or simultaneously with imagewise exposure, in a substantially water-free condition to imagewise form a mobile dye; and transferring the mobile dye into a dye fixing material using water, wherein in transferring the mobile dye, the amount of water present in all the coatings of the light-sensitive material and the dye fixing material is within a range of from 0.1 time the total weight of all the coatings to the difference obtained by subtracting the total weight of all the coatings from the weight of water corresponding to the maximum swollen volume of all the coatings.
Claim 3
Dependent Claim 19 words
A process as claimed in Claim 1, wherein the amount of water is 0.8 time or less the difference.
Claim 4
Dependent Claim 25 words
A process as claimed in Claim 1, wherein the water is supplied to at least one of the dye fixing material and the light-sensitive material.
Claim 5
Dependent Claim 19 words
A process as claimed in Claim 1, wherein the heating is conducted at a temperatuer of 80°C or more.
Claim 6
Dependent Claim 35 words
A process as claimed in Claim 1, wherein the substantially water-free condition is a condition which is in an equilibrium state with respect to water in air and with no addition of water from outside.
