    Abstract: PROBLEM TO BE SOLVED: To provide a titanium dioxide produced by thermal decomposition which exhibits satisfactory transparency and does not cause an unpleasant and dull feeling on a skin when used as a tanning preventive agent, and to provide a formulation for a tanning preventive agent using the same. SOLUTION: The titanium dioxide is surface-modified and covered with the silicon dioxide, is produced by the thermal decomposition, and especially, is produced by flame hydrolysis. The titanium dioxide and the formulation for a tanning preventive agent using the same is obtained by spraying a surface-treating agent onto the titanium dioxide covered with silicon dioxide, followed by treating the resultant product at a certain temperature.

    Abstract: PROBLEM TO BE SOLVED: To solve a following problem: a remarkably defected coated face (orange-peel skin) is obtained, when using a well-known silica, because rheology of a coating system is affected largely irrespective of using a special dispersion device.SOLUTION: The coating composition contains 5-99.5 mass% of solid of a polymer component, or a mixture comprising two or more physically or chemically crosslinked polymer components, (coupling agent component and curing agent component), 0-80 mass% of low-molecular weight component acting as a solvent, or mixture of such a low-molecular weight components, 0.5-50 mass% of silanized, structurally modified thermally decomposed silica to the surface of which there are attached an alkyl silyl group (SiCH1, where n is 2-18), and/or dimethyl silyl group, and/or monomethyl silyl group, and silanated to be modified structurally, and 0-10 mass% of commercially available additives.
