Abstract: Crosslinked copolymers containing crosslinkable groups based on acrylic acid or methacrylic acid which are obtainable by copolymerisation of (a) from 50 to 99 parts by weight of acrylic acid and/or methacrylic acid, (b) from 1 to 50 parts by weight of at least one N-methylol(meth)acrylamide, or derivatives thereof, (c) from 50 to 10000 ppm, based on monomers (a) and (b), of an at least bifunctional crosslinking agent and (d) from 0 to 49 parts by weight of other monoethylenically unsaturated monomers, in the presence of polymerisation initiators which form free radicals, a process for the preparation of the crosslinkable copolymers by copolymerising the monomers (a), (b), (c) and, if used, (d) in the aqueous phase of a water-in-oil emulsion, and the use of the copolymers as thickeners for textile printing pastes.
