Patent number: 5688961Abstract: A method of manufacturing charge transporting materials which impart a charge transporting property to a polysiloxane resin, and which is soluble in the resin. The charge transporting material is an aromatic substituted tertiary amine with a plurality of aromatic groups, and a silyl group introduced via a hydrocarbon group, into at least one of the aromatic groups. The method is characterized by using an unsaturated aliphatic group bonded to an aromatic group which makes up the silicon-type charge transporting compound, or using a newly bonded unsaturated aliphatic group which is bonded to a silane in which the substituent for silicon is hydrogen or a hydrolyzable group. This is conducted in the presence of a platinum compound as catalyst by means of hydrosilylation. The silicon-type charge transporting material is then brought into contact with an adsorbent for the platinum compound, causing the platinum compound to be adsorbed onto the adsorbent.Type: GrantFiled: November 4, 1996Date of Patent: November 18, 1997Assignee: Dow Corning Asia, Ltd.Inventors: Nobuo Kushibiki, Kikuko Takeuchi
