URETHANE (METH)ACRYLATE, RESIN COMPOSITION AND PRINTING INK RESIN COMPOSITION CONTAINING THE SAME, AND CURED PRODUCTS THEREOF

摘要

PURPOSE:To obtain the title compound which can give a resin composition capable of, in turn, giving a cured product excellent in light and weathering resistances and is suitable especially for a printing ink by reacting a hindered amine compound with an organic polyisocyanate and hydroxylated (meth)acrylic ester. CONSTITUTION:A hindered amine compound having a group of formula I in the molecule (e.g. a compound of formula II or III) is allowed to react with an organic polyisocyanate (e.g. hexamethylene diisocyanate) and a hydroxylated (meth)acrylic ester [e.g. beta-hydroxyethyl (meth)acrylate] to obtain a urethane (meth)acrylate. This compound can give a resin composition which, in turn, can give a cured product of excellent light and weathering resistances and is suitable especially for a printing ink.
