    Abstract: The invention relates to the use of water-soluble, amphoteric copolymers which can be obtained by the copolymerization of a) at least one N-vinyl carboxylic acid amide of general formula (I), wherein R1 and R2 independently represent H or C1 to C6 alkyl, b) at least one monomer which is selected from the group consisting of (b1) monoethylenically unsaturated sulfonic acids, phosphonic acids, phosphoric esters and derivatives thereof, and (b2) monoethylenically unsaturated monocarboxylic acids and dicarboxylic acids, the salts thereof and dicarboxylic anhydrides, c) optionally at least one monoethylenically unsaturated monomer which is different from components (a) and (b), and d) optionally at least one compound which has at least two ethylenically unsaturated double bonds in the molecule, with the proviso that the monomer mixture contains at least one monomer (b) with at least one free acid group and/or an acid group in the ionic form, and subsequent partial or complete hydrolysis of the groups -CO-R1 from the monomers (a) that are polymerized into the copolymer. The copolymers according to the invention are used as agents for increasing the initial wet strength of paper.
