<P>PROBLEM TO BE SOLVED: To provide a transparent sheet that has high heat resistance, surface hardness, refractive index, transparency, and gas barrier properties, satisfies properties with a low coefficient of thermal expansion, is cured by heat and ultraviolet rays, has molding processability while semi-cured, and is completely cured later. <P>SOLUTION: A resin composition (D) containing a condensate (A) obtained by hydrolysis and condensation of a thiol group-containing alkoxysilane: R<SP>1</SP>Si(OR<SP>2</SP>)<SB>3</SB>, a compound (B) having a carbon-carbon double bond, and a compound (C) having an isocyanate group with a ratio [a number of the double bond included in the component (B)/a number of the thiol group in the component (A)] being 0.1-0.8, a ratio [a number of the isocyanate group included in the component (C)/a number of the thiol group in the component (A)] being 0.1-0.8, and a ratio [a number of the carbon-carbon double bond included in the component (B)+a number of the isocyanate group in the component (C)/a number of the thiol group in the component (A)] being 0.9-1.1 is subjected to a two step-curing with heat and ultraviolet rays. <P>COPYRIGHT: (C)2010,JPO&INPIT |
