Active energy ray-curable pressure-sensitive adhesive composition, pressure-sensitive adhesive and pressure-sensitive adhesive sheet

摘要

The purpose of the present invention is to provide an active-energy-ray-curable composition containing a urethane (meth)acrylate having a low dielectric constant and excellent compatibility. The present invention relates to an active-energy-ray-curable composition containing a urethane (meth)acrylate (A) which is a product of reaction of a polyester-based polyol (a1), a polyisocyanate (a2), and a hydroxyl-group-containing (meth)acrylate (a3), the dielectric constant of the urethane (meth)acrylate (A) being 7.0 or less.
