COMPOSITION FOR OPTICAL MATERIAL, OPTICAL MATERIAL, PROCESS FOR PRODUCING THE SAME, AND LENS

摘要

An optical material which is reduced in coloration due to an ultraviolet absorber, is highly colorless and transparent, and has an excellent balance among material properties required of optical materials; a process for producing the optical material; a lens; and a composition to be used as a raw material for these optical materials. The composition comprises one or more monomers including a diallyl compound and additives including an ultraviolet absorber and an alcohol compound (1) represented by the formula (1): (1) wherein R<1> is phenyl or substituted phenyl; and R<2> and R<3> each represents C1-3 alkyl or hydrogen.
