(57) [Summary] An optical material having high light resistance and high toughness, Provided are a sealing material for a light emitting diode, an electronic material, and a light emitting diode using the same. (A) An organic compound having at least two carbon-carbon double bonds reactive with a SiH group in one molecule, (B) a compound having at least two SiH groups in one molecule, C) A curable composition having a hydrosilylation catalyst as an essential component, wherein the component (A) is represented by the following general formula (I): (In the formula, R 1 represents a monovalent organic group having 1 to 50 carbon atoms.) Wherein the component (B) is a linear siloxane compound containing SiH groups at both ends, or a composition for an optical material comprising a curable composition or both ends. A curable composition characterized by being a reaction product of a chain siloxane compound containing a SiH group and the above-mentioned component (A) as a composition for an optical material or a composition for an electronic material. |
