Abstract: A self-crosslinking aqueous preparation contains an aqueous dispersion of an anhydride group (AH)-containing copolymer (P); and a crosslinker (A) with a primary and/or secondary amine group (AM). A self-crosslinking aqueous preparation contains (i) an aqueous dispersion of an anhydride group (AH)-containing copolymer (P) obtained by radical aqueous emulsion copolymerisation of ethylenically-unsaturated monomers (M) comprising at least a monomer (M1) which is an anhydride of an unsaturated 3-8C carboxylic acid and a comonomer (M2); and (ii) a crosslinker (A) with a primary and/or secondary amine group (AM), this being (A1) a compound with at least 2 AMs; (A2) a compound with at least 1 AM and a siloxane group; (A3) an aminoalcohol; or (A4) a polymer with AMs. An Independent claim is also included for preparation of the composition by mixing an aqueous dispersion of copolymer (P) with (A), optionally in dissolved or dispersed form.
