Composition for optical material, optical material and photochromic lens |
| abstract |
A high-refraction photochromic lens exhibiting a quick optical response and a low specific gravity and being excellent in heat resistance, impact resistance and so on; an optical material useful as the material of the lens; and a composition useful as the raw material of the optical material. The composition comprises 100 parts by weight of a monomer composition comprising 15 to 97 wt% of at least one compound (A) represented by the general formula (1) wherein j + n = 5 to 7 and 3 to 50 wt% of at least one compound (B) represented thereby wherein j + n = 9 to 11 and 0.001 to 10 parts by weight of a photochromic compound: (1) wherein R1 and R2 are each H or CH3; Ph is phenylene; j and n are each an integer of 0 to 11, with the proviso that j and n are not simultaneously 0 ; and k, m and p are each 0 or 1. |
