ACTINIC-RADIATION CURABLE COMPOSITION AND USES THEREOF

摘要

Provided is an actinic-radiation curable composition which exhibits fast curability and which can yield a cured product having a high refractive index. The composition comprises: a urethane (meth)acrylate compound that has a specific structure containing both a sulfur atom and an aromatic ring; and a monofunctional (meth)acrylate that has a specific structure containing an aromatic ring. By virtue of use of the monofunctional (meth)acrylate as the diluent monomer, the composition exhibits a lowered viscosity while keeping excellent optical characteristics inherent in the urethane (meth)acrylate compound.
