A method of providing an image on a media having a image-receiving layer and a protective overlayer, comprising the steps of providing an image on the image-receiving and providing machine-readable indicia on said protective overlayer by varying the temperature of a thermal head used to apply the protective overlayer.

Label and method of making

A thermal donor element having a dye layer on an extruded substrate, wherein the extruded substrate includes a polyester-containing material and a slip agent, but does not contain silica particles, is disclosed.

Extruded slipping layer for thermal donor

A thermal printing ribbon that has reduced or no wrinkling during printing includes inorganic particles in a polymeric host material in at least one layer of the ribbon. The ribbon has improved mechanical and thermal properties as compared to ribbons not incorporating the inorganic particles. The ribbon can be used to form images on a dye-receiver element wherein the images have few or no artifacts caused by wrinkling of the thermal printing ribbon. The ribbon can be used in high speed printing.

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.
