Abstract

Abstract A process for forming a color image which may be used to represent a printed color image to be obtained from a printing press comprising (a) forming a thermal dye transfer image in a polymeric dye image-receiving layer of an intermediate dye-receiving element by imagewise-heating a dye-donor element and transferring a dye image to the dye image-receiving layer, (b) applying a dye-migration barrier layer to one surface of a paper substrate, and (c) transferring the imaged polymeric dye image-receiving layer to the surface of the paper having the dye-migration barrier layer applied thereon. By first applying a dye-migration barrier layer to the paper substrate, dye smear and spreading due to migration of dye into the paper can be eliminated and a high quality final color image can be obtained.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 78 words
A process for forming a color image comprising: (a) forming a thermal dye transfer image in a polymeric dye image-receiving layer of an intermediate dye-receiving element by imagewise-heating a dye-donor element and transferring a dye image to the dye imagereceiving layer, (b) applying a polymeric dye-migration barrier layer to one surface of a paper substrate, and (c) transferring the imaged polymeric dye image-receiving layer to the surface of the paper substrate having the dye-migration barrier layer applied thereon.
Claim 2
Dependent Claim 78 words
A process for forming a color image comprising: (a) forming a thermal dye transfer image in a polymeric dye image-receiving layer of an intermediate dye-receiving element by imagewise-heating a dye-donor element and transferring a dye image to the dye imagereceiving layer, (b) applying a polymeric dye-migration barrier layer to one surface of a paper substrate, and (c) transferring the imaged polymeric dye image-receiving layer to the surface of the paper substrate having the dye-migration barrier layer applied thereon.
Claim 3
Dependent Claim 20 words
The process of claim 1 wherein the polymeric dye-migration barrier layer is applied to the paper substrate by heat lamination.
Claim 4
Dependent Claim 49 words
The process of claim 1 wherein step (b) comprises laminating an element comprising a support having on one surface thereof the polymeric dye-migration barrier layer to the paper substrate such that the barrier layer is adhered to the paper substrate, and thereafter separating the support from the barrier layer.
Claim 5
Dependent Claim 62 words
The process of claim 1 wherein the intermediate receiver element comprises an intermediate support bearing on one surface thereof the dye image-receiving layer, and wherein step (c) comprises laminating the intermediate receiver element to the paper substrate such that the imaged dye image-receiving layer is adhered to the dye-migration barrier layer, and thereafter separating the intermediate support from the dye image-receiving layer.
Claim 6
Dependent Claim 20 words
The process of claim 4 wherein the polymeric dye-migration barrier layer is applied to the paper substrate by heat lamination.
Claim 7
Dependent Claim 49 words
The process of claim 4 wherein step (b) comprises laminating an element comprising a support having on one surface thereof the polymeric dye-migration barrier layer to the paper substrate such that the barrier layer is adhered to the paper substrate, and thereafter separating the support from the barrier layer.
Claim 8
Dependent Claim 22 words
The process of claim 6 wherein the polymeric dye-migration barrier layer and the polymeric dye image-receiving layer both comprise the same polymer.
Claim 9
Dependent Claim 12 words
