  • Patent number: 4477312
    Abstract: A method for producing a composite foil which has metallic lustrous layer areas with an image structure for transferring onto a base, comprising(a) applying at least one continuous lacquer layer on a carrier layer;(b) applying a continuous metal layer onto at least one lacquer layer;(c) applying a solvent resistant layer onto the metal layer, said solvent resistant layer being divided into areas which have the shape of the image structure, leaving areas of the continuous metal layer and the at least one continuous lacquer layer thereunder uncovered by the solvent resistant layer;(d) removing said uncovered areas of the continuous metal layer and the at least one continuous lacquer layer thereunder by treatment with a solvent therefor; and(e) applying a continuous adhesive layer onto the image structure carrying side of the treated composite foil from step (d), which adhesive layer fills said removed areas between the image structure and covers said areas and said image structure.
