ABSTRACT:
A composite strip material for forming graphics such as letters, numbers, symbols or pictures. The strip includes an accepting tape comprising a layer of latent adhesive material in face-to-face contact with a layer of microgranules lightly adhered to a donor web. At least one of the layers bears a radiation absorbing pigment which, when selectively heated in accordance with a pattern of radiation, momentarily softens adjacent portions of the adhesive material. Upon separation of the accepting tape and donor web, microgranules transfer to the accepting tape only in irradiated areas.
