Abstract

Self-adhesive coatings are produced on sheet materials in a simple and particularly trouble-free manner by applying to said materials mixtures of PA1 1. acrylic ester copolymers containing polymerized units of unsaturated carboxylic acids or hydroxyl-containing vinyl monomers in addition to polymerized units of higher alkyl acrylates, PA1 2. melamine/formaldehyde resins and, optionally, PA1 3. solvents for components (1) and (2), And evaporating off any solvents.
