Coatable thermal mass transfer precursor compositions, suitable for producing thermal mass transfer donor elements, are described, the coatable compositions comprising a polyalkylene binder precursor; an acrylic binder precursor; an effective amount of a pigment to provide the desired color to a thermal mass transfer composition using the coatable composition; and d) a diluent (preferably water) in which the polyalkylene binder precursor, acrylic binder precursor, and pigment are all dispersed therein. Signage articles produced using the donor elements are also described.

Compositions and thermal mass transfer donor elements for use in producing signage articles

A thermal mass transfer imaging process comprises the thermal mass transfer of a dye-receptive transparent donor layer which is then at least partially over-coated with a thermally transferred dye image.

Mass transferable donor ribbons for use in thermal dye transfer imaging

A thermal mass transfer donor element comprising a carrier layer having on one surface thereof a mass transferable layer of thermoplastic organic polymeric binder and metal flakes, said metal flakes having an average ratio of length to thickness of greater than 20:1.
