| abstract |
The present invention relates to a thermosetting resin composition for realizing a cured product that is easily cured by heating and can satisfy various properties such as heat resistance, chemical resistance, high surface hardness, and high refractive index. It aims at providing and the hardened | cured material obtained from the said composition. A general formula (1): R 1 Si (OR 2 ) 3 (1) (In the formula, R 1 represents a hydrocarbon group having 1 to 8 carbon atoms having at least one thiol group, or an aromatic hydrocarbon group having at least one thiol group, and R 2 represents a hydrogen atom, having 1 to 1 carbon atoms. And a condensate (A) obtained by hydrolysis and condensation of a thiol group-containing alkoxysilane (a1) represented by 8 hydrocarbon group or aromatic hydrocarbon group, and a compound having an epoxy group ( A thermosetting resin composition comprising at least one selected from B) and / or a compound (C) having an isocyanate group.
