2. Description of the Related Art Titanium oxide has a high UV shielding effect and is often used as a pigment in cosmetics and the like for preventing discoloration of paints due to UV rays and for preventing inflammation due to UV rays. To obtain titanium oxide in the form of flakes or fine particles suitable for this purpose, the sol-gel method, whose shape and particle size are easily controlled, is widely used. However, in this method, addition of water is indispensable for hydrolyzing the titanium alkoxide, and a lower alcohol such as butanol is used as the dispersion medium. Therefore, the titanium oxide obtained by the sol-gel method is poor in lipophilicity, and when it is dispersed in an oily material, good dispersion is not obtained, and when it is blended in an oily cosmetic or an oily coating, the dispersibility is improved. It was necessary to perform a hydrophobizing treatment in order to impart water resistance or water resistance. Further, in order to form a film, it is difficult to obtain a water resistant film when a water-soluble polymer compound having film forming property is used, and when a resin is used, titanium oxide is removed from the resin. There was a problem that a phenomenon called "chalking" that occurred when it was discharged and became powdery occurred.

Further, in resin compositions and containers which require resistance to ultraviolet rays, such as packaging materials and containers for foods, cosmetics, pharmaceuticals, materials for medical instruments, etc., an ultraviolet absorber is kneaded or contains an ultraviolet absorber. It was necessary to perform a surface treatment with the polymer compound. Therefore, deterioration and bleeding of the ultraviolet absorber itself due to exposure to ultraviolet rays are likely to occur, which has been a problem in terms of quality maintenance and safety.

[0005]

Therefore, in the present invention, it is possible to obtain a strong lipophilic film composition which can be applied in a wide variety of fields and is excellent in water resistance and ultraviolet absorption, and particularly to a composition for skin. , Coating compositions, resin compositions and containers.

[0006]

Means for Solving the Problems Already, the present inventors have found that when a hydrolysis reaction is allowed to proceed in a titanium alkoxide or an oily solution or dispersion thereof, a molecule of titanium oxide is formed during the growth of titanium oxide particles from the titanium alkoxide. By adding an appropriate amount of an organic compound having an atom and / or a polar group having a lone electron pair therein, titanium oxide particles dispersed in an oil dispersion medium in a transparent state are obtained, and the oil dispersion is further concentrated, It has been found and disclosed that those obtained by removing the dispersion medium have an excellent film-forming ability and can be easily applied in the fields of skin compositions, coating compositions, resin compositions and containers (Japanese Patent Application No. 2000-242242). Flat 11-20026). As a result of further study to solve the above problems,
By thinning the oily dispersion or the concentrate thereof or the dispersion medium-removed product, and then subjecting it to a heat treatment to such an extent that the organic compound remains, excellent water resistance and ultraviolet absorption, and a strong coating composition is obtained. Found that
The present invention has been completed.

That is, in the present invention, one or more organic compounds having an atom and / or a polar group having a lone electron pair in the molecule and water are added to a titanium alkoxide or an oily solution or dispersion thereof. One or two or more of the above-mentioned organic compounds are obtained by hydrolyzing and obtaining an oily dispersion of titanium oxide, and further, directly or concentrating the oily dispersion, or removing the dispersion medium from the oily dispersion to form a thin film. Is heat-treated to such an extent as to remain to obtain a coating composition. In addition, after coating the powder or the resin surface or the container surface with the above-mentioned titanium oxide oil dispersion or a concentrate thereof, a heat treatment is carried out to the extent that one or more organic compounds remain to give a strong parent. A powder or resin or container whose surface is coated with an oily film is obtained. Then, the surface-coated powder or resin is applied to various fields such as skin compositions and coating compositions. When hydrolyzing the titanium alkoxide, a gel of flaky or acicular particles can be selectively obtained by allowing one or more of the hydrolysis inhibitors to coexist. If necessary, an acid or a base or a salt formed by these can be used as a catalyst.

When the organic compound having an atom having a lone electron pair and / or a polar group in the molecule is liquid, the organic compound may be added directly to the titanium alkoxide. The shape of titanium oxide produced can be controlled by adjusting the type of organic compound having an atom having a lone electron pair and / or a polar group in the molecule and the amount added to the titanium alkoxide.
