Abstract
A thermal transfer donor element is provided which comprises a support, a light-to-heat conversion layer, an interlayer, and a thermal transfer layer. When the above donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. The construction and process of this invention is useful in making colored images including applications such as color proofs and color filter elements.
Claims6
A thermal transfer element, comprising a substrate having deposited thereon in the following order:
- (a) a light-to-heat conversion layer;
- (b) an interlayer;
- and
- (c) a thermal transfer layer,
- wherein the light-to-heat conversion layer comprises a radiation cured resin.
A thermal transfer element, comprising a substrate having deposited thereon in the following order:
- (a) a light-to-heat conversion layer;
- (b) an interlayer;
- and
- (c) a thermal transfer layer,
- wherein the light-to-heat conversion layer comprises carbon black dispersed in a crosslinked organic binder.
A process for transferring an image onto a receptor, comprising the steps of:
- a) placing in intimate contact the receptor and a thermal transfer element comprising a substrate having deposited thereon in the following order:
- (i) a light-to-heat conversion layer comprising a radiation cured resin;
- (ii) an interlayer;
- and
- (iii) a thermal transfer layer, the thermal transfer layer being in contact with a surface of the receptor;
- b) exposing the thermal transfer element in an imagewise pattern with a radiation source;
- and
- c) transferring the thermal transfer layer corresponding to the imagewise pattern to the receptor to form a transferred image on the receptor with substantially no transfer of the interlayer.
