Abstract

The present invention is directed to aqueous dispersion compositions in the form of aqueous, spreadable coating or printing pastes, characterized in that they contain PA0 (A) aqueous dispersions of polyurethanes (Aa) or mixtures of polyurethanes (Aa) and aqueous dispersions of poly(meth)acrylates (Ab), PA0 (B) carboxyl group-containing, aqueous thickener polymer solutions, PA0 (C) self-crosslinking polyorganosiloxane mixture and PA0 (D) crosslinking agents for the polyurethanes, for the carboxyl group-containing thickener polymers (B) and, optionally, for the poly(meth)acrylates. The present invention is also directed to a process for the preparation of these aqueous dispersion compositions and to their use for coating or printing substrates.
