FIELD: chemistry.

SUBSTANCE: invention relates to acrylic polymers, curable film-forming compositions obtained therefrom, and methods for reducing the accumulation of dirt on substrates. Disclosed is an acrylic polymer prepared from a reaction mixture comprising (i) an ethylenically unsaturated monomer containing hydroxyl functional groups; (ii) an ethylenically unsaturated polymer containing polydialkylsiloxane functional groups; (iii) silicon dioxide nanoparticles, the surface of which is modified using compounds containing ethylenically unsaturated functional groups, and (iv) an ethylenically unsaturated monomer containing fluorine. Also disclosed are a curable film-forming composition, comprising said acrylic polymers, a coated substrate comprising said curable film-forming composition applied to at least one surface of the substrate, and a method for reducing accumulation of dirt on a substrate using said composition.

EFFECT: effective cleaning of the substrate from dirt without destroying its surface.
