(57) [Summary] [Structure] UV curing for Fresnel lenses containing aromatic epoxy acrylate, polyester urethane acrylate containing bisphenol A ethylene oxide adduct as diol component, aromatic monofunctional acrylate and photopolymerization initiator as essential components. Resin composition; a transmissive screen having a Fresnel lens produced by curing the composition on a substrate. [Effect] Excellent adhesion to the substrate containing methyl methacrylate as the main component, easy molding, and the cured resin is It has a high refractive index, is tough, and has excellent chemical resistance, heat resistance, and cold resistance, and is extremely useful as a material for Fresnel lenses. Further, the transmissive screen having a Fresnel lens produced by curing the resin composition has good handleability, and since the refractive index is high, it is possible to make a projection television with a large screen size thin and compact. It is useful. |
