<P>PROBLEM TO BE SOLVED: To provide a resin composition (curable resin composition) formable of a cured product (resin cured product) having a high refractive index, and excellent in low moisture permeability, and small curing shrinkage. <P>SOLUTION: This resin composition comprises a compound (A) expressed by formula (1); at least one compound (B) selected from the group consisting of a condensate of phenols and aldehyde, a condensate of aromatic hydrocarbon and aldehydes, petroleum resin, styrenated phenol, and rosin. In formula, R<SP POS="POST">a</SP>s are each independently a reactive functional group; R<SP POS="POST">1</SP>s are each independently a halogen atom, alkyl group, haloalkyl group, aryl group; a hydroxy group which may be protected by a protecting group; hydroxyalkyl group which may be protected by a protective group; an amino group which may be protected by a protective group, a carboxy group which may be protected by a protective group, a sulfo group which may be protected by a protective group, nitro group, cyano group or an acyl group which may be protected by a protective group; R<SP POS="POST">2</SP>shows a single bond or a linking group; ms each independently denotes an integer of 0-4; and n denotes an integer of 0-10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
