Abstract
A thermal transfer medium which forms images having a matte finish is provided which comprises a substrate, a thin first coating and a thick second coating. The coatings are formulated such that only the second coating transfers to a receiving substrate upon exposure to a thermal print head leaving the first coating positioned on the substrate. Separation of the two coatings provides images with a matte finish. The first coating has a higher softening point than the second coating and in preferred embodiments, the binder resin in the first coating provides higher adhesion to the substrate than the binder resin in the second coating.
