Abstract

The invention relates to a water-based paint composition for aerosol cans containing A) 55 to 75% w/w of a paint component, which contains 40 to 75% w/w, with respect to the paint component, of an acrylate-based film-forming formulation in an aqueous medium, up to 10% w/w of a water-miscible polar solvent, up to 30% w/w of customary pigments, up to 15% w/w of matting agents, 2 to 15% w/w of additives, and up to 40% w/w of added water, and B) 25 to 45% w/w of a propellant gas component which, based on the propellant gas component, contains at least 75% w/w of dimethyl ether.
