Abstract:
1. A light-shielding paste which contains, as essential components, (A) an organic compound containing at least two carbon-carbon double bonds reactive with a SiH group in each molecule, (B) a silicon compound having at least two SiH groups in each molecule, (C) a hydrosilylation catalyst, (D) a silane coupling agent and/or an epoxy group-containing compound, (E) a silanol condensation catalyst, and (F) titanium oxide (F) titanium oxide being of rutile type and having an average particle diameter of 0.1 to 1.0 μm, wherein the amount of (F) titanium oxide in the light-shielding paste is not less than 5% by weight of the total weight of the light shielding paste wherein the component (A) is a mixture of triallyl isocyanurate and monoglycidyl diallyl isocyanurate and the component (B) is the reaction product from 1,3,5,7 tetramethylcyclotetrasiloxane and triallyl isocyanurate.
