  • Patent number: 4177309
    Abstract: Dry transfer materials, e.g. dry transfer lettering sheets, are made from a transparent or translucent carrier sheet indicia thereon (e.g. in printing ink or produced photographically) and a layer of adhesive over the indicia and on the carrier sheet in the areas between the indicia. By incorporating a suitable amount of a detackifying polar wax in the adhesive, when the adhesive is deposited from a solution and/or dispersion in an organic solvent, the adhesive dries down to be stickier over the indicia than in the areas where it is directly on the carrier sheet.
