Patent ID: 8062824

Claim:
A multilayer thermal imaging donor comprising: a) a base film; and b) a dielectric transfer layer comprising at least one Layer A comprising: one or more dielectric polymer(s) selected from the group consisting of: acrylic and styrenic polymers selected from the group consisting of: acrylic, styrenic and styrenic-acrylic latexes, solution-based acrylic, styrenic and styrenic-acrylic polymers, and combinations thereof; heteroatom-substituted styrenic polymers selected from the group consisting of: partially hydrogenated poly(4-hydroxystyrene), poly(4-hydroxystyrene), and copolymers of poly(4-hydroxystyrene) with hydroxyethyl (meth)acrylate, alkyl (meth)acrylate, styrene, and alkyl-substituted styrene wherein the alkyl group is a C1 to C18 straight or branched chain alkyl group; phenol-aldehyde (co)polymers and (co)oligomers and combinations thereof; and poly(vinyl acetate); and about 0.5 wt % to about 10 wt %, based on the dry weight of Layer A, of one or more near-IR dye(s) having an absorption maximum in the range of 600 to about 1200 nm within Layer A; wherein the dielectric transfer layer has a resistivity of 10 14 ohm-cm or greater.
