Abstract:
1. A method for producing a silicone resin sheet, comprising the steps of: forming a first coating layer by applying a first silicone resin composition which contains a first organopolysiloxane having at least two alkenylsilyl groups in one molecule and a second organopolysiloxane having at least two hydrosilyl groups in one molecule; forming a precursor layer from the first coating layer by reacting the first organopolysiloxane with the second organopolysiloxane so as to have a conversion ratio of 5 to 40%; and forming a second layer on at least one surface in a thickness direction of the precursor layer by applying a second silicone resin composition which contains a third organopolysiloxane having at least two alkenylsilyl groups in one molecule, a fourth organopolysiloxane having at least two hydrosilyl groups in one molecule, a hydrosilylation catalyst, and a curing retardant containing tetraalkylammonium hydroxide.
