Реферат: The present invention is directed to curable film-forming compositions and coating kits comprising: (a) a polyisocyanate; (b) a dispersion comprising a polymer dispersed in an organic medium and prepared from an ethylenically unsaturated monomer having functional groups that are reactive with the polyisocyanate (a); and optionally (c) an adhesion promoter. The organic medium comprises a diluent having functional groups that are reactive with the polyisocyanate (a), the diluent comprising at least one of castor oil, a dimerized fatty acid diol, a hydroxyl functional branched polyolefin oil, a cashew nutshell liquid (CNSL)-based diol, a polycaprolactone-based polyol, and an alkoxylated polyol comprising a hydroxyl group. The curable film-forming composition has a solids content of at least 45 percent by weight, and demonstrates a viscosity of at most 100 centipoise (100 mPas). The present invention is also drawn to coated articles and vehicle components comprising the film-forming composition.
