摘要： The present invention provides products comprising cocoon-shaped rutile-type titanium dioxide, i.e., cosmetics which have high UV blocking ability, provide a good feel upon use without leaving squeakiness or graininess on the skin, and also give a natural bare skin appearance without causing white masking, due to adequate tinting strength and covering power, as well as external additives for toner which are excellent in prevention of filming on a photosensitive member and inhibition of aggregation between toner particles. The present invention is directed to rutile-type titanium dioxide having a cocoon-shape, as well as cosmetics comprising this titanium dioxide, and external additives for toner comprising this titanium dioxide which is hydrophobically treated.

摘要： The improved white conductive powder comprises white inorganic pigment particles the surfaces of which are coated with an electrically conductive layer of a dual structure consisting of a lower tin dioxide sub-layer and an upper tin dioxide-containing indium oxide sub-layer. To produce the powder, the hydration product of tin is deposited uniformly on the surfaces of white inorganic particles and, subsequently, an overcoat of indium oxide hydrate containing 0.1-20 wt % of tin dioxide is formed, followed by a heat treatment that is conducted at 350.degree.-750.degree. C. in a non-oxidizing atmosphere. A resin composition containing this powder retains both the good conduction properties of a white conductive resin composition incorporating a conductive powder the particles of which are coated with antimony-doped tin dioxide and the high photostability of a white conductive resin composition incorporating an aluminum-doped conductive zinc oxide powder and yet the composition has a much higher degree of whiteness than either prior art resin composition.
