Lowly lactone-modified reactive monomer composition, acrylic polyol resins produced with the same, curable resin compositions and coating compositions

摘要

A lowly lactone-modified hydroxyalkyl (meth)acrylate composition essentially consisting of monomers represented by general formula (1), which is prepared by ring-opening polymerization of lactone with hydroxyalkyl (meth)acrylate and the content in which of such monomers having two or more lactone chain units (n=2) is less than 50% (GPC area %); a process for producing the composition; acrylic polyol resins produced with the same; curable resin compositions; and coating compositions.
