Abstract
A silicone-based copolymer resin powder is prepared by reacting a siloxane oligomer obtained from ring-opening of (a1) a cyclic organosiloxane in the presence of (a3) an acid catalyst and (a4) an anionic surfactant with (a2) a silane coupling agent having an alkoxy group and a polymerizable double bond to obtain (A) a linear or branched organopolysiloxane containing at least 2 silicon-bonded hydroxyl groups per molecule,
