Abstract
An ionizing radiation-curable resin composition which provides a cured product having no yield point in the stress-strain diagram in tension is disclosed. An optical article prepared from the ionizing radiation-curable resin composition and a surface light source using the optical article are also disclosed. The present invention provides an excellent ionizing radiation-curable resin composition, an excellent optical article comprising a cured product of the resin composition, and an excellent surface light source using the optical article, which have high surface hardness and a high refractive index and are free from deformation, permanent sets, and reduction in weather resistance after curing.
