Abstract:
A developer sheet useful in forming reproductions which have a controllable gloss finish or in forming transparencies comprising a support having a layer of a finely divided, thermoplastic, developer material on the surface thereof, said developer material being capable of reacting with a color precursor to produce a visible image and being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure. The developer sheet comprising a support having a layer of a finely divided thermoplastic developer material on the surface thereof can additionally comprise oil-containing microcapsules such that upon microcapsule rupture, the oil plasticizes the developer material.
