ABSTRACT:
A composite material for forming graphics such as letters or numbers. The composite material includes a layer of latent adhesive material, a mono-layer of granules lightly adhered to a donor web, and a thin layer of bonding material between and in face-to-face contact with the layers of granules and adhesive. The layer of bonding material maintains the adhesive and granular layers in close proximity and excludes air from therebetween. When the composite material is selectively heated in graphic patterns, corresponding portions of the bonding layer melt; and corresponding portions of the adhesive material and granular layer soften, absorb the melted portions of the bonding layer and adhere together. Upon subsequent separation of the layer of adhesive and the donor web the remaining portions of the layer of bonding material separate, whereas granules transfer to the accepting tape in the heated areas to provide the graphics.
