Abstract

Abstract A process is described for reheating a dye image-receiving element containing a thermally-­transferred dye image and stabilizer. Stratifica­tion of the transferred dye image in the receiving element is thereby reduced, resulting in an increase in stability to light of the transferred dyes.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 102 words
A process of forming a stable dye transfer image comprising: a) imagewise-heating a dye-donor element comprising a support having thereon a dye layer, b) transferring a dye image to a dye-receiving element to form a dye transfer image, said dye-receiving element comprising a support having thereon a dye image-receiving layer containing a stabilizer compound to increase the stability to light of said transferred dye image, and c) heating said dye-receiving element containing said transferred dye image, so that stratification of said transferred dye image in said dye-receiving element is reduced, thereby further increasing the stability to light of said transferred dye image.
Claim 2
Dependent Claim 102 words
A process of forming a stable dye transfer image comprising: a) imagewise-heating a dye-donor element comprising a support having thereon a dye layer, b) transferring a dye image to a dye-receiving element to form a dye transfer image, said dye-receiving element comprising a support having thereon a dye image-receiving layer containing a stabilizer compound to increase the stability to light of said transferred dye image, and c) heating said dye-receiving element containing said transferred dye image, so that stratification of said transferred dye image in said dye-receiving element is reduced, thereby further increasing the stability to light of said transferred dye image.
Claim 3
Dependent Claim 22 words
The process of Claim 1 characterized in that said heating of said-dye receiving element is accomplished by using a thermal print head.
Claim 4
Dependent Claim 22 words
The process of Claim 1 characterized in that said heating of said dye-receiving element is accomplished by using a separate heating device.
Claim 5
Dependent Claim 15 words
The process of Claim 3 characterized in that said heating device is a heated roller.
Claim 6
Dependent Claim 53 words
The process of Claim 1 characterized in that said stabilizer compound has the following moiety: wherein each R independently is an alkyl or substituted alkyl group of from 1 to 20 carbon atoms, or two adjacent R groups may be joined together to form methylene or ethylene; and x is at least 2.
Claim 7
Dependent Claim 26 words
The process of Claim 5 characterized in that each R independently is an alkyl group of from 1 to 10 carbon atoms and x is 4.
Claim 8
Dependent Claim 49 words
The process of Claim 1 characterized in that said stabilizer compound has the following moiety: wherein each R¹ and R² is independently an alkyl or substituted alkyl group of from 1 to 20 carbon atoms, or two adjacent R¹ groups may be joined together to form methylene or ethylene.
Claim 9
Dependent Claim 24 words
The process of Claim 7 characterized in that each R¹ and R² independently is an alkyl group of from 1 to 6 carbon atoms.
Claim 10
Dependent Claim 47 words
The process of Claim 1 characterized in that the support for the dye-donor element comprises poly(ethylene terephthalate) which is coated with sequential repeating areas of cyan, magenta and yellow dye, and said process steps are sequentially performed for each color to obtain a three-color dye transfer image.
