    • [PROBLEMS] To provide polymerizable compounds useful as the raw material for resins which have high refractive indexes (nd) exceeding 1.7 as well as satisfy the requirements for optical members such as plastic lenses, e.g., high transparency, good heat resistance, and satisfactory mechanical strengths, and optical members made of the resin. [MEANS FOR SOLVING PROBLEMS] Compounds represented by the general formula (3) wherein M is a metal atom; X 1 and X2 are each independently sulfur or oxygen; R 1 is a divalent organic group; m is an integer of 0 or above; p is an integer of 1 to n; q is an integer of 1 to (n-p); n is the valence of M; and Yq's are each independently an organic or inorganic group; with the proviso that when q is 2 or above, Yq's may be bonded to each other to form a cyclic structure together with M.
    • [问题]提供可用作高折射率(nd)超过1.7的树脂的原料的可聚合化合物,并且满足诸如塑料透镜的光学构件的要求,例如高透明度,良好的耐热性和令人满意的机械 强度和由树脂制成的光学构件。 解决问题的手段由通式(3)表示的化合物,其中M为金属原子; X 1和X 2各自独立地为硫或氧; R 1是二价有机基团; m为0以上的整数; p为1〜n的整数; q为1〜(n-p)的整数。 n是M的化合价; Yq各自独立地为有机或无机基团; 条件是当q为2或更高时,Yq可以彼此键合以与M一起形成环状结构。
