Abstract

Abstract An intermediate dye image-receiving element for thermal dye transfer comprising a support having thereon a separable polyolefin layer, a dye image-receiving layer, and a subbing layer between the polyolefin layer and the dye image-receiving layer, characterized in that the subbing layer comprises a crosslinked poly(vinyl acetal-co-vinyl alcohol). The intermediate receiver is used in a process for formation of a dye image in an arbitrarily shaped object which includes the following steps: (a) forming a dye transfer image by thermal dye transfer in a dye image-receiving layer of an intermediate dye receiving element comprising the dye image-receiving layer, subbing layer, polyolefin layer, and support, (b) separating the imaged dye image-receiving layer from the support, (c) placing the separated, imaged, dye image-receiving layer in contact with an arbitrarily shaped final receiver, (d) transferring the dye image out of the dye image-receiving layer and into the final receiver by the action of heat, and (e) removing the dye image-receiving layer from the imaged final receiver resulting from step (d).

Claim 2
Dependent Claim 25 words
The element of Claim 1 further characterized in that the support comprises a cellulose based paper support and the polyolefin layer is extrusion coated thereon.
Claim 3
Dependent Claim 16 words
The element of Claim 1 further characterized in that the dye image-receiving layer comprises a polycarbonate.
Claim 4
Dependent Claim 22 words
The element of Claim 1 further characterized in that a receiver overcoat layer comprising polycaprolactone is coated on the dye image-receiving layer.
Claim 5
Dependent Claim 32 words
The element of Claim 1 further characterized in that the poly(vinyl acetal-co-vinyl alcohol) before cross-linking comprises wherein n is 90 to 60 mole %, and m is 10 to 40 mole %.
Claim 6
Dependent Claim 26 words
The element of Claim 5 further characterized in that the poly(vinyl acetal-co-vinyl alcohol) is cross-linked with a dialdehyde, a diisocyanate, an epoxide, or a dihydric phenol.
Claim 7
Dependent Claim 135 words
A process for formation of a dye image in an arbitrarily shaped object comprising: (a) forming a dye transfer image by thermal dye transfer in a dye image-receiving layer of an intermediate dye-receiving element comprising a support having thereon a separable polyolefin layer, the dye image-receiving layer, and a subbing layer between the polyolefin layer and the dye image-receiving layer, (b) separating the imaged dye image-receiving layer from the support, (c) placing the separated, imaged, dye image-receiving layer in contact with an arbitrarily shaped final receiver, (d) retransferring the dye image out of the dye image-receiving layer and into the final receiver by the action of heat, and (e) removing the dye image-receiving layer from the imaged final receiver resulting from step (d), charaterized in that the subbing layer comprises a crosslinked poly(vinyl acetal-co-vinyl alcohol).
Claim 8
Dependent Claim 17 words
The process of Claim 7 further characterized in that the intermediate dye image-receiving layer comprises a polycarbonate.
Claim 9
Dependent Claim 32 words
The process of Claim 7 further characterized in that the poly(vinyl acetal-co-vinyl alcohol) before cross-linking comprises wherein n is 90 to 60 mole %, and m is 10 to 40 mole %.
Claim 10
Dependent Claim 26 words
The process of Claim 9 further characterized in that the poly(vinyl acetal-co-vinyl alcohol) is cross-linked with a dialdehyde, a diisocyanate, an epoxide, or a dihydric phenol.
