摘要： Disclosed are a powder of indium-tin oxide aciculae suitable as an electroconductive filler for an electroconductive ink to be used for forming a transparent electroconductive film, a method for producing a raw material to be used for producing the powder of indium-tin oxide aciculae, which has a major diameter of 5 &mgr;m or more and a ratio of the major diameter to the minor diameter of 5 or more, an electroconductive paste capable of forming a light-transmitting electroconductive film having sufficient electroconductivity and light transmittance by printing, such as screen-printing, followed by high-temperature baking, and a light-transmitting electroconductive film to be formed from the paste. The raw material is produced by heating and concentrating an aqueous solution containing indium ions and nitrato ions to form a high-viscosity slurry followed by separating a powder of aciculae from the slurry. By calcining the raw material, a powder of indium-tin oxide aciculae is produced.

摘要： A new composition of titanyl phthalocyanine is provided. This composition has in its infrared absorption spectrum characteristically strong absorptions at absorption wavenumbers (in unit of cm.sup.-1) of 1490.+-.2, 1415.+-.2, 1332.+-.2, 1119.+-.2, 1072.+-.2, 1060.+-.2, 961.+-.2, 893.+-.2, 780.+-.2, 751.+-.2 and 730.+-.2, and has an extremely high solvent stability and dispersibility, and a large photoelectric conversion efficiency. The new form of composition can be obtained by adding to titanyl phthalocyanine, compounds of other phthalocyanines or naphthalocyanines as additives, and treating the amorphous composition of the mixture to crystallize the composition. By applying an appropriate binder, with the novel composition crystals as a charge generation agent, on a substrate, it is possible to obtain an electrophotographic photosensitive material that has a charge generation layer with an extremely high dispersibility and an extremely large photoelectric conversion efficiency.
