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.
