  • Patent number: 4175151
    Abstract: A method of producing decal transfers having the steps of printing color on a solvent-soluble separation layer on a solvent permeable backing producing a picture, applying a solvent-soluble cover to the area surrounding the picture, and applying a protective-transfer foil over the picture and the cover. The foil is insoluble in the solvent. The cover dissolves in the solvent during the course of the transfer operation thereby removing any impurities arising in the unprinted area surrounding the picture. A decal transfer consists of a solvent-permeable backing carrying a solvent-soluble separation layer thereon, a printed color picture on the separation layer, a solvent-soluble cover on the separation layer in at least the picture-free areas, and an insoluble protective-transfer foil covering the picture and the majority of the cover.
