摘要

PROBLEM TO BE SOLVED: To provide a multibranched unsaturated urethane compound having a multifunctional (meth)acrylate residue at the molecular chain terminal, and to provide a method for producing the compound.;SOLUTION: The multibranched urethane compound comprises a repeating branching unit represented by general formula (1) {wherein, R₁ and R₂ are each independently a hydrogen atom and/or a 1-6C alkyl group or substituted alkyl group; X is an organic residue having two or more oxygen atoms derived from hydroxy groups (n is ≥2); and Y is a di- or more-valent organic residue (m is ≥1)} and having two or more urethane bonds through a sulfide bond.;COPYRIGHT: (C)2008,JPO&INPIT
