摘要:
A radiation curable resin composition for a Fresnel lens is provided, which exhibits a high elastic modulus and a high refractive index and is superior in adhesion to the plastic substrate and is superior in transparency. A lens layer exhibits excellent shape retention over a wide temperature range and is less likely to chip and crack due to an external force. A Fresnel lens sheet using the radiation curable resin composition is also provided. The resin composition comprises, as an essential component, an epoxy (meth)acrylate (a) having an epoxy equivalent per weight of 450 g/eq or more, which has a cyclic structure and two or more (meth)acryloyl groups; a specific trifunctional (meth)acrylate (b); a (meth)acrylate (c) having a molecular weight of 700 or less from an aliphatic polyhydric alcohol having an oxypropylene structure; and a monofunctional (meth)acrylate (d) having a cyclic structure.
