Ionizing radiation curable resin composition for fresnel lens and transmission screen

Abstract

Disclosed is an ionizing radiation curable resin composition is provided which is suitable for the production of optics, such as Fresnel lenses, with a high refractive index, possessing good scratch resistance. The ionizing radiation curable resin composition for a Fresnel lens comprises the following components (A) to (D), the radiation curable resin composition providing, upon curing, a cured product having a refractive index of not less than 1.55: A transmission screen prepared using the resin composition is also disclosed. (A) A bisphenol A epoxy(meth)acrylate represented by chemical formula 1 wherein R represents H or CH3 and n is an integer of 1 or more; (B) a monofunctional (meth)acrylate; (C) a bifunctional (meth)acrylate; and (D) a polymer.
