    • The fluorine-containing epoxy(meth)acrylate resin of the invention is represented by the following general formula (I). ##STR1## wherein R.sub.f is selected from the group consisting of --.phi.--C(CF.sub.3).sub.2 --.phi.--(where .phi. stands for ##STR2## --C(CF.sub.3).sub.2 --.phi.'--C(CF.sub.3).sub.2 --(where .phi.' stands for and --CH.sub.2 (CF.sub.2).sub.6 CH.sub.2 --; n is zero or a positive interger; and X is hydrogen or methyl group. The resin of the invention may be prepared by reacting a diglycidyl ether of a fluorine-containing hydrocarbon (R.sub.f) with acrylic acid or methacrylic acid. Further provided is an adhesive composition comprising the aforementioned fluorine-containing epoxy(meth)acrylate resin and a photo-polymerization initiator, which can be cured at room temperature within a short time by irradiation with UV rays to form a cured product having a refractive index N.sub.D.sup.20 ranging from 1.434 to 1.532. The adhesive composition of the invention has a particular utility when used to form a part or zone contacting with a quartz glass or glass fibers, since it is improved in matching of the refractive index with those of the quartz glass and optical fibers.
    • 本发明的含氟环氧(甲基)丙烯酸酯树脂由以下通式(I)表示。 其中R f选自-Phi -C(CF 3)2 - phi - (其中phi代表 -C(CF 3)2-phi '-C(CF 3)2 - (其中,phi'代表和-CH 2(CF 2)6 CH 2 - ; n为零或正整数; X为氢或甲基,本发明的树脂可以制备 通过使含氟烃(Rf)的二缩水甘油醚与丙烯酸或甲基丙烯酸反应,还可以提供含有上述含氟环氧(甲基)丙烯酸酯树脂和光聚合引发剂的粘合剂组合物,其可以固化 在室温下通过紫外线照射在室温下形成折射率ND20为1.434〜1.532的固化物,当用于形成与石英接触的部分或区域时,本发明的粘合剂组合物具有特别的用途 玻璃或玻璃纤维,因为折射率与石英玻璃的折射率匹配得到改善 和光纤。
