The present invention relates to a protective heat transferable overcoat element comprising a support having thereon a protective polymer layer of at least one benzoated phenoxy resin of Formula I. The present invention also relates to a thermal transfer dye donor element comprising a support having on one side thereof at least one dye layer and a protective polymer layer of at least one benzoated phenoxy resin of Formula I and a thermal transfer assemblage comprising at least one thermal transfer donor element comprising a support having on one side thereof a protective polymer layer of at least one benzoated phenoxy resin of Formula I. Finally, the present invention relates to a protected image reproduction comprising a support, an imaging layer containing an image, and a transferred protective heat transferable overcoat comprising a protective polymer layer of at least one benzoated phenoxy resin of Formula I.

Thermally transferable image protection overcoat

This invention relates to a method for transferring a protective overcoat for a thermal print wherein the protective overcoat is applied to a dye-donor element under predesigned conditions after thermal dye transfer, the dye-donor element comprising patches of dye for transfer to a thermal print to provide a protective layer thereon. In particular, the invention improves the process of providing an improved level of gloss to the transferred protective overcoat. The method involves a preselected duration between printing and peeling the transferable laminate patch, respectively, to and from the donor. The invention is particularly advantageous at lower line times, faster printing, for thermal prints with high gloss.

Method of transferring a protective overcoat to a dye-donor element

A process of transferring a protection layer from a dye-donor receiver after thermal dye transfer. In one embodiment, the transferable protection layer contains inorganic particles, a polymeric binder, organic particles and an organic gloss-enhancing agent that enhances the gloss of the final print. The transferred protection layer that provides a higher gloss to an image after transfer. A laminate containing such a gloss-enhancing agent has been found to enable printing at lower line times, faster printing, for thermal prints withwhile maintaining high gloss.

Acceleration of silver removal by thioether compounds

An interactive dye thermal transfer printing apparatus and process uses a dye donor layer and a dye receiver layer, passing the dye donor layer and the opposed receiver layer between a thermal print head and a platen heated to raise the temperature of the dye receiver layer to its glass transition temperature. The thermal print head is image-wise energized to diffuse dye from the dye donor layer to the dye receiver layer. At the same time, thermal energy is transferred from the platen to the dye receiver layer to provide energy to react the dye with the receiver layer.
