<P>PROBLEM TO BE SOLVED: To provide a multi-functional (meth)acrylate composition having excellent optical characteristics such as low chromatism, high light transmittance, etc., excellent in various characteristic balances required for an optical lens/prism material, and even under an actual severe using condition such as a moist and hot condition, maintaining a high degree of the optical characteristics without causing the bifurcation of refractive index. <P>SOLUTION: This resin composition consisting of a component (A) and a component (B) is provided with that the component (A) is a copolymer having a polymerizable group, and obtained by copolymerizing a component containing (a) a mono-functional (meth)acrylate having an alicyclic type structure, (b) a mono-functional (meth)acrylate having an alcoholic hydroxy group, (c) a bi-functional (meth)acrylate and (d) 2,4-diphenyl-4-methyl-1-pentene, the component (B) is a monomer having ≥1 functional group having an unsaturated double bond, and the blending amount of the component (A) is 1 to 70 wt.%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
