Process for controlling the gloss of a thermal dye transfer image

A dye-donor element for thermal dye transfer comprising a support having thereon a coextensive subbing layer and at least one dye layer area comprising an image dye in a binder and another area comprising a transferable protection layer, the transferable protection layer area being approximately equal in size to the dye layer area, the transferable protection layer having associated therewith a release material comprising a multi-hydroxyl compound, the alkali or alkaline earth metal salt of an alkyl diphenyloxide disulfonate, or an organic phosphate ester.

A microfluidic pen for selectivly writing lines of different colors, includes a colorant mixing chamber and a writing tip in communication with the colorant mixing chamber; a plurality of colorant reservoirs disposed in the pen and which contain different colorants; microkinetic pump selectively effective to deliver colorant in selected amounts from the colorant reservoirs to the colorant mixing chamber wherein the colorants are mixed to provide a colorant of the desired color. The color is selected by a user and actuates the microkinetic pump to cause the desired amount of colorants to be delivered to the colorant mixing chamber where the writing tip can write a line of the desired line colors.

Plasticizers for dye-donor element used in thermal dye transfer

This invention relates to a dye-donor element for thermal dye transfer comprising a support having thereon a dye layer comprising an image dye in a polymeric binder, and wherein the dye layer also contains a polymeric plasticizer having a Tg less than about 25.degree. C., the plasticizer comprising ##STR1## wherein: R and R.sup.1 each independently represent a substituted or unsubstituted linear or branched alkylene, phenylene or cycloalkylene group of from 1 to about 12 carbon atoms; and n is an integer selected so that the plasticizer has a polystyrene equivalent weight average molecular weight of from about 18,000 to about 300,000.

A thermal printer has converging paths for dye-donor web and receiver medium. The paths abut before proceeding past the thermal head. A transport system moves the dye-donor web and the receiver medium (i) in a forward direction along their respective paths past a thermal head, whereat heat from the thermal head causes an area of the laminate material coating between leading and trailing edges to transfer from the dye-donor web to the receiver medium and (ii) in a reverse direction along their respective paths such that the area of the laminate material which is transferred to the receiver medium breaks cleanly at said trailing edge from a non-laminated area of the laminate material that remains on the aye-donor web as the web support separates from the receiver medium.
