发明名称 Thermal image receiver elements having release agents
摘要 A thermal image receiver element dry image receiving layer has a Tg of at least 25° C. and is the outermost layer. The dry image receiving layer has a dry thickness of at least 0.5 μm and up to and including 5 μm. It comprises a water-dispersible release agent and a polymer binder matrix that consists 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. The water-dispersible acrylic polymer is present in an amount of at least 55 weight % and at a dry ratio to the water-dispersible polyester of at least 1:1. The thermal image receiver element can be used to prepare thermal dye images after thermal transfer from a thermal donor element.

主权项 1. A thermal image receiver element comprising a support, and having on at least one side of the support: a dry image receiving layer having a Tg of at least 25° C., which dry image receiving layer is the outermost layer of the thermal image receiver element, has a dry thickness of at least 0.5 μm and up to and including 5 μm, and comprises a water-dispersible release agent, and a polymer binder matrix that consists essentially of: (1) a water-dispersible acrylic polymer comprising chemically reacted or chemically non-reacted hydroxyl, phospho, phosphonate, sulfo, sulfonate, carboxyl, or carboxylate groups, and(2) a water-dispersible polyester that has a Tg of 30° C. or less,wherein the water-dispersible acrylic polymer is present in an amount of at least 55 weight % of the total dry image receiving layer weight; wherein the water dispersible release agent is selected from the group consisting of a water-dispersible fluorine-based surfactant, a silicone-based surfactant, a modified silicone oil, a polysiloxane, a modified polysiloxane and a cross-linked amino modified polydimethyl siloxane.
