PURPOSE: To provide an optic lens material which has a low tacking property, low moisture content, high refractive index, good flexibility and is easy to be handled, by making the lens material formed out of a polymer which is composed of a polymerization component in which a monomer expressed by a specified formula is contained and the composition containing a cross-linking agent. CONSTITUTION: This optic lens material is formed by a polymer which is obtained from polymerization of a polymerization component containing a monomer (A) which is expressed as a formula, such as 2-hydroxy-3- phenoxypropyl (meth)acrylate and of the composition containing a cross-linking agent. Where, R<1> is hydrogen atom or methyl group, R<2> to R<6> are respectively hydrogen atom, alkyl group, alkoxyl group, hydroxyl group, carboxyl group independently, and (n) represents an integer of 1 to 10. The amount of monomer (A) used is made to be 15∼99weight% of weight components so as to fully exert its effect of improving flexibility, reducing a tacking property, and increasing refractive index, especially 25weight% is preferable. |
