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.
