ABSTRACT:
Radiation-curable acrylated urethanes having a lower viscosity than heretofore achievable without dilution are produced by an improved process that involves first reacting a monohydroxy-functional acrylate with a polyisocyanate followed by the reaction of the product mixture produced with a polyol. The acrylated urethanes so produced are useful in radiation-curable coatings.
