Abstract: Disclosed are anhydrous transparent dispersions of polyurethane(meth)acrylate particles in a reactive diluent, which can be obtained by reacting a polyisocyanate with at least one polyol and a nucleophilically functionalized (meth)acrylic acid ester in the reactive diluent. The inventive dispersions are characterized in that the polyurethane(meth)acrylate particles have an average diamert of less than 40 nm. The invention further relates to a method for producing such dispersions, the use thereof as an adhesive, cut glass, or impact resistance modifier, and a molded article made from said dispersion.
