Conductive thermal imaging receiving layer with receiver overcoat layer comprising a surfactant

摘要

This invention relates to a conductive thermal image receiver element that has an aqueous-based coatable dye-receiving layer comprising a water-dispersible acrylic polymer, a water-dispersible polyester, a water-dispersible conductive polymeric material and a surfactant. This invention also relates to a method for making this thermal image receiver element as well as method for using it to provide a dye image by thermal transfer from a donor element.

主权项

1. A conductive thermal image receiver element comprising a support, and having on at least one side of the support:
an aqueous coatable receiver overcoat layer and aqueous coatable dye receiving layer having a combined thickness ranging from 0.8 μm to 2.0 μm, wherein the aqueous coatable receiver overcoat layer comprises a conductive polymeric material, a surfactant, and one or more dispersants, wherein at least one of the one or more dispersants is a polymer comprising benzyl methacrylate and methacrylic acid, and wherein the aqueous coatable dye receiving layer comprises a water-dispersible release agent, a crosslinking agent, and a polymer binder matrix consisting essentially of:
(1) a water-dispersible acrylic polymer comprising chemically reacted or chemically non-reacted hydroxyl, phospho, phosphonate, sulfo, sulfonate, carboxy, or carboxylate groups; and(2) a water-dispersible polyester that has a Tg of 30° C. or less.
