Abstract
A thermal transfer medium is provided which is sufficiently opaque to be sensed by optical sensing means, yet forms images which can be transparent or semi-transparent (or opaque). The thermal transfer medium comprises a transparent substrate and multi-layer structure of a thin first coat and a thick second coating. The coatings are formulated such that only the second coating transfers to a receiving substrate upon exposure to a print head of a thermal printer leaving the first coat positioned on the transparent substrate. Separation of the two coatings allows the transparency/opacity of the image to be independent of the transparency/opacity of the first coats and the thermal transfer medium.
