Abstract
A silicone resin composition contains a first organopolysiloxane having, in one molecule, both at least two ethylenically unsaturated hydrocarbon groups and at least two hydrosilyl groups; a second organopolysiloxane having, in one molecule, at least two hydrosilyl groups without containing an ethylenically unsaturated hydrocarbon group; a hydrosilylation catalyst; and a hydrosilylation inhibitor.
