(57) [Summary] [Structure] Aromatic epoxy acrylate, urethane acrylate containing bisphenol A ethylene oxide adduct as a diol component, aromatic monofunctional acrylate, lauryl alcohol ethylene oxide adduct and phosphoric acid monoester, and photopolymerization initiation. A UV-curable resin composition for a Fresnel lens containing an agent as an essential component; and a transmission 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, cold resistance, and antistatic properties, 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. |
