Abstract
Fluorescent security thermal transfer printing ribbons consisting of an elongated backing element having a printing media adhered to one side thereof. The printing media is capable of being transferred to paper, or some other print receiving medium, by conventional thermal transfer printing equipment. The thermally transferred printing media includes an interspersed distribution of fluorescent pigments, resulting in printed security characters and images which are transparent or invisible under broad spectrum light, but which fluoresce, and become visible, when exposed to black light.
