<p>1. A pressure-sensitive adhesive consisting of (A) a copolymer having a softening point of -60 to 0 degree C derived from (a) 60 to 99.88% by weight of an ester of acrylic or methacrylic acid with an alkanol of 4 to 12 carbon atoms, (b) 0.1 to 5% by weight of at least one monomer having at least one hydroxyl group, (c) 0.02 to 5% by weight of at least one monomer having at least one tert.-amino group, and (d) 0 to 30% by weight of other copolymerizable monomers, (B) such an amount of a polyisocyanate having at least two isocyanate groups per molecule that 0.001 to 1 equivalent of isocyanate groups is present per equivalent of OH groups of monomer (b), (C) 10 to 900% by weight, based on the amount of (A), of an organic solvent which is inert to (A) and (B), and optionally (D) conventional additives.</p> |
