Abstract
A composite resin is produced by hydrolyzing and condensing a silane compound (2) containing a bissilane compound (B) represented by:XRSi—Y—SiRX  (B)wherein Y is a divalent organic group which is optionally substituted with a fluorine atom or a divalent organic group which optionally contains an aromatic ring, R is a monovalent organic group, X is OH group or a hydrolyzable group, and n is 1, 2, or 3; in the presence of (1) porous and/or hollow inorganic oxide fine particles (A); and which is an integral mixture of component (1) and component (2) which has undergone the hydrolysis and the condensation. The composite resin has voids in the resin since it contains porous and/or hollow inorganic oxide fine particles, and the composite resin can also be formed into a cured article or a cured coating with a reduced refractive index since it contains air which has the lowest refractive index.
