Abstract
Production of low-emission dispersion paints, coating materials and synthetic resin dispersion plasters in the form of aqueous preparations based on aqueous synthetic resin dispersion copolymers derived from olefinically unsaturated monomers, having a pigment volume concentration (PVC) of at least 60% and containing water, fillers, pigments, synthetic resin dispersion copolymers and conventional auxiliaries, wherein the synthetic resin dispersion copolymers have a content of 0.05 to 2% by weight of monomer units derived from special unsaturated hydrolyzable organic silicon compounds and the aqueous copolymer dispersions possess a minimum film-forming temperature (MFT) of <10.degree. C., preferably <5.degree. C. and especially <2.degree. C., the aqueous preparations according to the invention contain <0.1% by weight of volatile non-aqueous constituents, based on the total non-volatile part of the preparations, and the pH of the aqueous preparations is in the range from 5.5 to 10.
