Abstract of the disclosure 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 con- ventional auxiliaries, wherein the synthetic resin dis- persion copolymers have a content of 0.05 to 2% by weight of monomer units derived from special unsaturated hydro- lyzable organic silicon compounds and the aqueous copolymer dispersions possess a minimum film-forming temperature (MFT) of < 10°C, preferably < 5°C and especially < 2°C, the aqueous preparations according to the invention contain < 0 1X by weight of volatile non-aqueous con- stituents, 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 In particular, the low-emission aqueous preparations produced according to the invention are free of volatile organic solvents, volatile organic film-forming auxiliaries, low-molecular plasticizers, residual monomers from the preparation of the dispersion copolymer, other highly volatile non-aqueous constituents and malodorous by- products. Use of the dispersion paints, coating materials and synthetic resin dispersion plasters as building-protection materials or as structural materials, especially in spaces which are inadequately ventilated and inhabited
