Antimicrobial powders are obtained by suppporting at least one antimicrobial metal of copper, zinc and alloys thereof on the surface of hydrous titanium oxide or titanium oxide particles by electroless plating, vapor deposition, compression mixing, mixing and reducing, and thermal decomposition of a compound. These powders are used to provide antimicrobial resin compositions, antimicrobial rubber compositions, antimicrobial glass compositions and antimicrobial coating compositions.

Method of making titanium oxide powder having antimicrobial metal

The present invention aims at materialization of reproduction of an image of high quality by the color electrophotography process of the EF system according to a specific procedure of effecting back surface grounding of a photosensitive material sheet comprising a photosensitive layer consisting of titanium dioxide and a specific base sheet comprising a conductive support constituted by a conductive layer laminated on a highly smooth surface and highly specific resistivity base sheet on the basis of a conductive conveyor.

Color electrophotographic process uses layered photosensitive element

A chlorine-containing gas is introduced as an upward flow into a vertical, upwardly widening column-type reactor, and a titaniferous material and a solid carbonaceous reducing agent are charged into the reactor at its upper and lower parts to effect chlorination in a dilute-phase fluidization system accompanied by reflux of part of the solid materials and thereby yield titanium tetrachloride.
