  • Surface-modified fine silica powder and use thereof
    Patent number: 6994834
    Abstract: A surface modified fine silica powder which has been treated, preferably, with a treating agent containing an amino group, characterized in that the powder exhibits an adsorption amount for an anion source compound of 150% or more of that of an original powder which has not been treated; and a printing material using the silica powder. The surface modified fine silica powder can provide an excellent printed matter being free from blotting with ink or a cracking of coating film.
    Type: Grant

  • Surface modified inorganic oxide powder and its use
    Publication number: 20050203214
    Abstract: [Problem to be Solved]: To provide a surface modified inorganic oxide powder having a reduced amount of residual volatile components. [Solution]: The surface modified inorganic oxide powder is obtained by the surface treatment of an inorganic oxide powder with the use of a treating solution of long-chain alkylsilane and catalysts in a solvent or by the heat treatment of the inorganic oxide powder between the volatilization temperature of the organic volatile components and the decomposition temperature of the treating agents after the surface modification, to reduce the amount of the volatile components to less than 30 ppm, preferably less than 10 ppm.
