    摘要: A method for forming a low surface energy coating for electrophotographic photosensitive body substrates does not require performing a physical surface reforming treatment such as corona discharge, plasma treatment, and the like. The process comprises: forming on the substrate at least one polysiloxane coating material, (B), that has a water contact angle greater than the water contact angle of the substrate; and thereafter forming an outermost surface coating material, (A), on top of coating material (B). The water contact angle of coating material (B) is smaller than the water contact angle of coating material (A). Coating material (A) comprises finely divided silica and a resin of the formula RSiO.sub.3/2, wherein not less than 1 mol % and not more than 80 mol % of the R groups are fluorohydrocarbon groups of 3 to 12 carbon atoms.

    摘要: A process for the preparation of an electrically conductive coating material for use in electrophotography applications comprises subjecting an epoxy-functional silane to hydrolytic condensation in a mixed solvent of alcohol and water in the presence of silica. The hydrolyzed material is then heat cured to form a resin coating comprising (R.sup.1 SiO).sub.3/2 units, where R.sup.1 comprises epoxy-functional groups. The coating has superior optical homogeneity and electrical conductivity without being detrimental to the functionality required of electrophotographic photosensitive bodies.

    摘要: A conducting varnish composition consisting essentially of:(a) a tetracyanoquinodimethane complex salt;(b) a high molecular weight compound;(c)(i) at least one compound selected from the group consisting of acetals, orthoformic acid esters, orthoacetic acid esters, orthocarbonic acid esters, siloxanes, silyl ethers and orthosilicic acid esters; and/or(ii) a surfactant or a silicone oil; and(d) a solvent.the TCNQ complex salt is stable in a solution of the composition according to the present invention and the composition can be stored for a long period of time. Therefore, it provides a conducting material which exhibits a constant conductivity. Also, the composition of the present invention is excellent in the film-formability and moldability, and can be formed into a film or an article of good quality, that is, having no incomplete part.
