CURABLE COMPOSITION AND CURED PRODUCT THEREOF |
摘要 |
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).
