摘要： A curable resin composition comprising 5 to 90 % by weight of a dithiol having a diphenyl sulfide skeleton, 10 to 95 % by weight of a compound copolymerizable with the dithiol, and 0 to 40 % by weight of a monomer having two or more thiol groups as the monomer component; another curable resin composition comprising 5 to 100 % by weight of a derivative of the above dithiol, 0 to 95 % by weight of a compound copolymerizable with the derivative, and 0 to 50 % by weight of a monomer having two or more thiol groups as the monomer component; and resins made from these compositions. The compositions are excellent in curing characteristics and have high refractive indexes and high Abbe numbers in spite of their low specific gravities, so that they are extremely useful not only in the optical field but also as coating materials, adhesives, sealants, and so on.
摘要翻译：一种可固化树脂组合物，其包含5至90重量％的具有二苯硫醚骨架的二硫醇，10至95重量％的可与二硫醇共聚的化合物和0至40重量％的具有两个或更多个硫醇基团的单体作为单体组分; 另一种可固化树脂组合物，其包含5至100重量％的上述二硫醇衍生物，0至95重量％的可与该衍生物共聚的化合物和0至50重量％的具有两个或更多个硫醇基团的单体作为单体组分; 和由这些组合物制成的树脂。组合物的固化特性优异，折射率高，阿贝数高，尽管比重低，但不仅在光学领域中，而且作为涂料，粘合剂，密封剂等也是非常有用的。

摘要： Novel sulfur compounds represented by general formula (I) wherein n represents an integer of 0 to 2 and R represents hydrogen, vinyl, methacryloyl, vinylbenzyl, glycidyl, acryloyl or allyl, provided the case where n is 0 to R is hydrogen is excluded. The compounds can be copolymerized with various comonomers to give excellent cured articles having a high refractive index. They are therefore usable as extremely useful monomers for producing optical materials, coating materials, adhesives, sealants, and so forth having excellent physical properties.
摘要翻译：由通式（I）表示的新型硫化合物，其中n表示0-2的整数，R代表氢，乙烯基，甲基丙烯酰基，乙烯基苄基，缩水甘油基，丙烯酰基或烯丙基，条件是n为0至R为氢的情况。这些化合物可以与各种共聚单体共聚以提供具有高折射率的优异的固化物。因此，它们可用作生产具有优异物理性质的光学材料，涂料，粘合剂，密封剂等的非常有用的单体。
