abstract |
This invention provides the curable composition which can form the lens which was excellent in the transcription | transfer precision of a metal mold | die, and was excellent in heat resistance and an optical characteristic. Curable composition for lenses of this invention contains the alicyclic epoxy compound (A) represented by Formula (a), a cationic polymerization initiator (B), and the polysiloxane (C) represented by Formula (c) at least, and the said polysiloxane ( C) is contained 0.01 to 5% by weight based on the total amount of the curable composition. The curable composition for lenses of this invention may further contain the siloxane compound (D) which has 2 or more epoxy groups in a molecule | numerator. |
