Abstract:
A printable swelling paste consisting of two components and based on a superabsorber, characterized in that component I comprisesa) an aqueous solution of a pre-crosslinked polymer of (meth)acrylic acid and/orb) an aqueous solution of a pre-crosslinked polymer of (meth)acrylic acid which is partially present as a salt, and/orc) a copolymer of at least 50 mol-% of an aqueous solution of a pre-crosslinked polymer of (meth)acrylic acid with acrylamide wherein (meth)acrylic acid is present in a molar excess,said aqueous pre-crosslinked polymer a), b) and c) having been obtained by incorporating a cross-linking agent by copolymerization with the monomer or monomers,and that component II comprises or consists of a different reactive crosslinking agent capable of reacting with carboxylate or carboxylic acid functions.
