  • Production of self-adhesive coatings on flat substrates
    Patent number: 4049847
    Abstract: Self-adhesive coatings are produced on sheet materials in a simple and particularly trouble-free manner by applying to said materials mixtures of1. acrylic ester copolymers containing polymerized units of unsaturated carboxylic acids or hydroxyl-containing vinyl monomers in addition to polymerized units of higher alkyl acrylates,2. melamine/formaldehyde resins and, optionally,3. solvents for components (1) and (2),And evaporating off any solvents.
