    • The present invention provides a curable composition having a proper viscosity and excellent handling properties, and a cured product that is obtainable by curing the curable composition and has excellent transparency, heat resistance and resistance to environment and a low Abbe's number, and further can effectively decrease chromatic aberration by the combined use with a material having a high Abbe's number.
      The curable composition is characterized by comprising (a) silica fine particles, (b) a (meth)acrylate compound having at least two ethylenic unsaturated groups and having no ring structure, (c) a (meth)acrylate compound having at least two ethylenic unsaturated groups and having an aromatic ring structure and (d) a polymerization initiator, wherein the silica particles (a) are surface treated by a specific silane compound (e) and a specific silane compound (f).
    • 本发明提供了具有适度的粘度和优异的处理性能的固化性组合物,以及通过使固化性组合物固化而得到的固化物,具有优异的透明性,耐热性,耐环境性和低的阿贝数,进一步可以有效降低 通过与具有高阿贝数的材料组合使用的色差。 固化性组合物的特征在于,包含(a)二氧化硅微粒,(b)具有至少两个烯键式不饱和基团且不具有环结构的(甲基)丙烯酸酯化合物,(c)具有至少两个烯属 不饱和基团并具有芳环结构,(d)聚合引发剂,其中二氧化硅颗粒(a)用特定的硅烷化合物(e)和特定的硅烷化合物(f)进行表面处理。
