Abstract

1. Process for improving the strength of paper, board or card materials by treating the surface of these materials with aqueous solutions of copolymers of (meth)acrylic acid derivatives and optionally customary additives, characterized in that the copolymers used are copolymers of 1. 0.1-10 % by weight of acrylonitrile, 2. at least 30 % by weight of acrylamide and 3. 30-60 % by weight of acrylic acid and/or methacrylic acid, which can optionally be present entirely or partially in the form of their ammonium salt.
