| abstract |
The present invention contains: (A) component: a hardenable polysesquioxane compound having a repeating unit represented by the formula: R1-D-SiO3/2 (wherein R1 represents a composition formula: CxH (2x-y+) 1) a fluoroalkyl group represented by Fy; x represents an integer of 1 to 10, y represents an integer of 2 or more and (2x+1) or less; and D represents a linking group to which R1 and Si are bonded (however, Except for alkyl groups) or single bonds. And a component (B): a sulfonate coupling agent having a nitrogen atom in a molecule; a curable composition, a method for producing the same, and a cured product formed by curing the curable composition, and using the curable composition A method of using an adhesive for an optical element fixing material or a sealing material for fixing an optical element, and an optical device. According to the present invention, it is possible to provide a curable composition having excellent adhesion and heat resistance and a low refractive index cured product, and a method for producing the same, and a cured product obtained by curing the curable composition, wherein the curable composition is used as light. A method for sealing an element fixing material or a sealing material for an optical element fixing material, and an optical device. |
