Abstract: Provided is an image transfer material, comprising an optional support material, and a non-woven or woven fiber web layer, wherein the fiber web is impregnated or coated with a image receiving formulation. The fiber web layer is optionally attached to the support with an adhesion layer. Also provided is a heat transfer process wherein after imaging, the fiber web and adhesion layer are peeled from the optional support material and placed, preferably image side up (when imaged), on top of a receptor element. Alternatively, the fiber web and adhesion layer are peeled and then optionally imaged prior to being placed on the receptor element. Then, an optional non-stick sheet is placed over the imaged fiber web (if placed imaged side up) and heat is applied to the fiber web or the non-stick sheet, if present. The adhesion layer then melts and adheres the imaged web layer to the receptor element.

Abstract: Polyester compositions are disclosed that include polyester polymers or copolymers having incorporated therein titanium nitride particles and carbon-coated iron particles to improve the reheat properties of the compositions. The compositions may also exhibit reduced yellowness, and improved resistance to the effects of UV light. Processes for making such compositions are also disclosed. The particles may be incorporated in the polyester by melt compounding, or may be added at any stage of the polymerization, such as during the melt-phase of the polymerization. A range of particle sizes may be used, as well as a range of particle size distributions. The polyester compositions are suitable for use in packaging made from processes in which a reheat step is desirable, or decreased yellowness is desired, or increased resistance to the effects of ultraviolet light is desired, or any combination of the foregoing.

Abstract: Disclosed is a protective transparent overcoat comprising a protective polymer and a surfactant compound having multiple non-end-group hydrogen bonding groups directly or indirectly bonded to the backbone chain of the surfactant compound. The coating enables simplified manufacturing of a thermal sublimation dye transfer donor of high quality.

Abstract: An aqueous coating formulation which forms a thermal transfer layer of a thermal transfer ribbon. This formulation comprises an aqueous emulsion of a thermoplastic resin and/or wax coemulsified with an epoxy curing agent. This emulsion can be combined with an aqueous dispersion of an epoxy resin. These coating formulations provide thermal transfer layers with reactive components that increase in molecular weight when heated during transfer to provide images with high scratch and smear resistance without organic solvents. The reactive components are maintained in separate phases within the same thermal transfer layer or separate thermal transfer layers until exposed to a thermal print head.
