Abstract

Innovative polyestersiloxane acrylates obtainable by reacting one or more organically modified polysiloxanes with one or more polyisocyanates having in each case at least two isocyanate groups and one or more polyester acrylates or polyester methacrylates and their use as additives in radiation-curable coatings and printing inks for improving the resistance of the coating toward soiling of all kinds.
