    摘要: An optical silica-containing polysiloxane resin comprises colloidal silica and a polysiloxane resin. The polysiloxane resin has the formula RSiO.sub.3/2, where R is selected from the group consisting of hydrocarbon groups of 1 to 4 carbon atoms and fluorohydrocarbon groups of 3 to 10 carbon atoms. The fluorohydrocarbon groups have the general formula C.sub.n F.sub.(2n+1) C.sub.2 H.sub.4 --, where n is an integer of 1 to 8. The optical silica-containing polysiloxane resin has high light transmissivity and high surface hardness, and can be used for optical elements.

    摘要: A method of manufacturing solvent-soluble charge transporting materials capable of imparting charge-tranporting properties to polysiloxane resins. These materials have the formula A-�R.sup.1 SiR.sup.2.sub.3-n Q.sub.n !.sub.p where A is a tertiary amine and organic group derived from a compound having charge transporting properties with an ionization potential of 4.5-6.2 eV; R.sup.1 is an alkylene group of 1-18 carbon atoms; R.sup.2 is a monovalent hydrocarbon group or a monovalent halogen-substituted hydrocarbon group of 1-15 carbon atoms; Q is a hydrolyzable group such as--OR.sup.3 where R.sup.3 is an alkyl group of 1-6 carbon atoms; n and p are each 1-3. This silicon-type charge transporting material is characterized by aromatic groups, and alkoxysilyl groups bonded via hydrocarbon groups onto the aromatic rings.
