Abstract
Described herein are photocurable compositions, (A) a polyester urethane acrylate, or methacrylate (A), (B) an acrylamide, or methacrylamide component (B), and (C) a photoinitiator (C), where the polyester urethane acrylate, or methacrylate (A) is obtained by reacting (A1) a hydroxyalkylacrylate, or hydroxyalkylmethacrylate, (A2) an aliphatic diisocyanate, an aliphatic polyisocyanate, a cycloaliphatic diisocyanate, a cycloaliphatic polyisocyanate, an aromatic diisocyanate, or an aromatic polyisocyanate, or mixtures thereof, (A3) a polyester polyol, and (A4) optionally a second polyol. The compositions, from which cured three-dimensional shaped articles having high toughness, high E modulus and impact strength can be made, are particularly suitable for the production of three-dimensional articles by stereolithography.
