RADICAL-POLYMERIZABLE COMPOSITION

摘要

A radical-polymerizable composition which comprises a urethane (meth)acrylate (A) having a structure derived from a polysiloxane (a) having a polyalkylene oxide chain as a side chain, a urethane (meth)acrylate (B) which does not have the structure derived from a polysiloxane (a) having a polyalkylene oxide chain as a side chain, and a polymerizable unsaturated monomer (C), wherein the urethane (meth)acrylate (A) is one obtained by bonding a polysiloxane (a) having a polyalkylene oxide chain as a side chain to a polymerizable monomer (d) having two or more polymerizable unsaturated double bonds through a compound (b) having an isocyanate group.
