Claim 2
Dependent Claim
52 words
In a dye-receiving element for thermal dye transfer comprising a support having thereon a dye image-receiving layer, the improvement wherein said support comprises a continuous oriented polymer matrix phase having dispersed therein microbeads of a crosslinked polymer coated with a slip agent and which are at least partially bordered by void space.
Claim 3
Dependent Claim
22 words
The dye-receiving element of claim 1 wherein the average size of said microbeads is from about 2 microns to about 30 microns.
Claim 4
Dependent Claim
16 words
The dye-receiving element of claim 1 wherein the continuous oriented polymer matrix phase comprises a polyester.
Claim 5
Dependent Claim
12 words
The dye-receiving element of claim 3 wherein the polyester is poly(ethylene terephthalate).
Claim 6
Dependent Claim
20 words
The dye-receiving element of claim 1 wherein the support comprises from about 30 to about 60 volume percent void space.
Claim 7
Dependent Claim
21 words
The dye-receiving element of claim 1, further comprising a smoothing layer between the void containing support and the dye image-receiving layer.
Claim 8
Dependent Claim
25 words
The dye-receiving element of claim 6 wherein the smoothing layer contains microbeads of a relatively smaller size than the beads in the void containing support.
Claim 9
Dependent Claim
92 words
In a process of forming a dye transfer image comprising: a) imagewise-heating a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a binder, and b) transferring a dye image to a dye-receiving element comprising a support having thereon a dye image-receiving layer to form said dye transfer image, the improvement wherein said dye-receiving element support comprises a continuous oriented polymer matrix phase having dispersed therein microbeads of a cross-linked polymer coated with a slip agent and which are at least partially bordered by void space.
Claim 10
Dependent Claim
92 words
In a process of forming a dye transfer image comprising: a) imagewise-heating a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a binder, and b) transferring a dye image to a dye-receiving element comprising a support having thereon a dye image-receiving layer to form said dye transfer image, the improvement wherein said dye-receiving element support comprises a continuous oriented polymer matrix phase having dispersed therein microbeads of a cross-linked polymer coated with a slip agent and which are at least partially bordered by void space.
Claim 11
Dependent Claim
21 words
The process of claim 8 wherein the average size of said microbeads is from about 2 microns to about 30 microns.
Claim 12
Dependent Claim

Claim 14
Dependent Claim
35 words
The process of claim 8 wherein said support is coated with sequential repeating areas of cyan, magenta and yellow dye, and said process steps are sequentially each color to obtain a three-color dye transfer image.
Claim 15
Dependent Claim
102 words
In a thermal dye transfer assemblage comprising: a) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a binder, and b) a dye-receiving element comprising a support having thereon a dye image-receiving layer, said dye-receiving element being in a superposed relationship with said dye-donor element so that said dye layer is in contact with said dye image-receiving layer, the improvement wherein the dye-receiving element support comprises a continuous oriented polymer matrix phase having dispersed therein microbeads of a cross-linked polymer coated with a slip agent and which are at least partially bordered by void space.
Claim 16
Dependent Claim
102 words
In a thermal dye transfer assemblage comprising: a) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a binder, and b) a dye-receiving element comprising a support having thereon a dye image-receiving layer, said dye-receiving element being in a superposed relationship with said dye-donor element so that said dye layer is in contact with said dye image-receiving layer, the improvement wherein the dye-receiving element support comprises a continuous oriented polymer matrix phase having dispersed therein microbeads of a cross-linked polymer coated with a slip agent and which are at least partially bordered by void space.
