Abstract

The present invention provides compounds having in their molecule a structure contributing to high hydrophilicity, and having high photopolymerizability, as well as polymers of such compounds, and a method for producing the compound. The compounds are diol (meth)acrylate having a urethane bond represented by the formula (1), and cyclic ketal (meth)acrylate having a urethane bond represented by the formula (2):

(R₁: H, —CH₃; R₂: —(CH₂)n-; R₃: —(CH₂)m-; n: 1-4; m: 1-8; (AO): C2-C4 oxyalkylene group; x: 0-1000; R₄, R₅: H, —CH₃, —C₂H₅).

Claims

1. A cyclic ketal (meth)acrylate compound having a urethane bond represented by the formula (2):
