URETHANE(METH)ACRYLATE HAVING FLUORENE SKELETON AND CURED PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide novel urethane(meth)acrylate having a fluorene skeleton, superior in hardness, heat resistance, and the like.;SOLUTION: The urethane(meth)acrylate is obtained by causing a compound having a specific fluorine skeleton (e.g., 9,9-bis[4-(2-hydroxyethoxy)phenyl]fluorene, 9,9-bis[4-(2-hydroxyethoxy)-3-methylphenyl]fluorene, 9,9-bis[3,4-di(2-hydroxyethoxy)phenyl]fluorene) and a (meth)acrylic compound having an isocyanate group (e.g., mono or di(meth) acryloyloxy C_2-6 alkyl-isocyanate such as 2-(meth)acryloyloxyethyl isocyanate (or 2-(meth)acryloxyethyl isocyanate), 1,1-bis((meth)acryloyloxymethyl)ethyl isocyanate) to react with reach other.;COPYRIGHT: (C)2014,JPO&INPIT
