WIPO Patent Application WO/2010/095475
Kind Code:
A1
Abstract:
A (meth)acrylate resin which gives, as an organic optical material, a cured object having a high refractive index and having excellent heat resistance and moisture resistance; a curable resin composition; a cured object obtained from the composition; and a plastic lens. A (meth)acrylate resin characterized by having a binaphthalene skeleton in the molecular structure and having a substituent represented by structural formula (A) as a substituent on the aromatic nuclei of the binaphthalene skeleton is cured by heating or irradiation with actinic energy rays. (In the formula, R1 is a linear or branched C2-5 alkylene; R2 is a hydrogen atom or methyl; and l, indicating the number of repeating units, is an integer of 1-10.)
