    摘要: An ink jet recording material excellent in all characteristics including drying property, ink absorbency, water resistance and the like, is provided. The ink jet recording material has an ink-receiving layer comprising hydrophilic resin and inorganic pigment, the ink-receiving layer containing silica particles surface-doped with alumina as the inorganic pigment. The alumina-doped silica is prepared by a process employing flame hydrolysis techniques combined with pyrolysis. The ink-receiving layer preferably contains the alumina-doped silica in an amount ranging from 5 to 200 weight parts based on 100 weight parts of the hydrophilic resin.

    摘要: A finely-divided cerium metal/metalloid oxide mixture, containing pyrogenically produced metal/metalloid oxide and 0.001 to 95 wt. % cerium oxide, has a specific surface area between 10 and 400 m.sup.2 /g. The mixture is produced by mixing pyrogenically produced metal/metalloid oxide, having a specific surface area between 30 and 400 m.sup.2 /g, with a cerium compound decomposable to an oxide at elevated temperature, the cerium compound being thermally decomposed to the oxide. The cerium oxide-metal/metalloid oxide mixture can be used as a polishing agent or filler.
