as components of the mixture. Optionally, the mixture may contain further additives, such as thickeners. The polymer component having carboxyl and amide groups is produced by free-radical copolymerization of monomers containing amide groups and monomers containing carboxyl groups, and other comonomers may be polymerized therein as well. The invention also relates to the use ofsaid swelling paste in the production of absorbent fibers, fabrics and sheet materials such as films by applying the swelling paste onto the support material and subsequent thermal treatment.

[ What is claimed is:] [1.] An article coated with a dried crosslinked paste, said article comprising a component selected from the group consisting of absorbent fibers, fiber bundles, filaments, fleeces, fabrics, and other prefabricated sheet materials, said article being made by applying the paste onto said article and subjecting said article to thermal treatment to dry and crosslink said paste, wherein said paste consists essentially ofA) a component 1, consisting of an aqueous, partially or completely neutralized solution of a polymer produced by free-radical copolymerization of mixtures consisting essentially ofa) 1-80 mole % of monomers containing amide groups,b) 20-99 mole % of monomers containing carboxyl groups and/or carboxylate groups, and,c) 0-49 mole % of other free-radical-polymerizable anionic or non-ionic monomers,B) a component 2, consisting of a crosslinker, and optionally,C) further additives which are not polymerizable with said polymer and said crosslinker,wherein the crosslinker component 2 is an aldehyde, or a compound that liberates aldehyde groups in the presence of water and upon heating, or hexamethylenetetramine, wherein said paste has the following properties:(1) crosslinking of said polymer by said crosslinker being capable of occurring within 5 minutes at a temperature of at least 160.degree. C., and(2) after being dried and crosslinked, being capable of swelling in the presence of water.
