Abstract
A dye-receiver element for thermal dye transfer includes a support having on one side thereof a dye image-receiving layer characterized in that a release agent is present in the dye-image receiving layer which release agent comprises a siloxane-containing polymer having a weight average molecular weight of at least 150,000 and a viscosity in the range of 10 million mm/sec to 50 million mm/second. The invention also relates to a process of making a dye-receiver element for thermal dye transfer from a dye-donor element, said dye-receiver element comprising a support having thereon a dye image-receiving layer made by a process comprising forming a melt of a thermoplastic material comprising the release agent, extruding or coextruding the melt as a single-layer film or a layer of a composite (multilayer) film; and applying the extruded film or composite film to a support for the dye-receiver element. The use of such a release agent provides improved non-sticking and improved image quality compared to other release agents.
