| description | Provided is a curable composition which has chargeability into silicone molds and curability at excellent levels, less causes the silicone molds to swell, and allows the silicone molds to have better durability and a longer service life in repeated use. The curable composition according to the present invention contains curable compounds and a cationic initiator and is used for production of an optical component by molding using silicone molds. The curable compounds include (A) a cycloaliphatic epoxy compound in a content of 10 weight percent or more of the totality of all the curable compounds contained in the curable composition. Of the totality of all the curable compounds contained in the curable composition, 10 to 50 weight percent is a curable compound or compounds having a molecular weight of 400 or more. |
