Abstract
A paper or transparency receiving toner to be fixed by heat has an ionomeric resin on its outer surface. For universal application, the outer layer is a blend of non-ionomeric resin, such as styrene acrylate copolymer, and an ionomer, which permits the material of the toner to molecularly intermingle with the blend during heat fixing. Irradiation raises the melting point of the ionomeric resin to prevent delamination. The resulting printing is strongly bonded to the substrate and is of excellent quality.
