    摘要: An iridescent multilayer pigment having at least two or more layers of metal oxides containing one or more metals selected from Ce, Sn, Ti, Fe, Zn and Zr which are coated onto the surface of thin platelet-like substrates. The inventive pigments show high brilliance and high chroma, in particular in cases in which thin platelet-like substrates having a fine average particle diameter are used. The pigment is useful in paints, printing inks, lacquers, plastics, dopants for laser marking, non-dusting pigment products, non-dusting pigment granules or cosmetics.

    摘要: A porous carrier for a catalyst comprising metal coated with metal oxide grains having a mean grain size of 150 nm or less and a mean pore diameter of 5.5 nm or less, is obtained by subjecting:(a) stainless steel;(b) (i) a metal alkoxide or (ii) a metal alkoxide and a metal acetate salt, both being soluble in alcohols;(c) a diol, cellosolve, or polyether which has coordinating capacity with the (i) metal alkoxide or (ii) metal alkoxide and metal acetate salt and which is soluble in alcohols; and(d) an alcohol solvent to hydrolysis and polycondensation, whereby the stainless steel is coated with an oxygen-containing organic metal compound and, subsequently, heat-treated to form a metal oxide. A method of preparing the catalyst is also provided.
