PROBLEM TO BE SOLVED: To provide a new shape-anisotropic tabular particle having a smooth surface in one surface, and an uneven surface in the other surface formed by spherical particles, further having anisotropy in light reflectivity, and exhibiting peculiar reflection effect.;SOLUTION: The shape-anisotropic tabular particle is composed of a tabular acrylic polymer particle and the spherical particles, of which one surface is the smooth surface (a) formed of an acrylic polymer 2, and of which the other surface is the uneven surface (b) formed of the spherical particles 3 protruded from the acrylic polymer. The shape-anisotropic tabular particle is produced by dissolving the acrylic polymer in a solvent, adding the spherical particles thereto to prepare a dispersion solution, spreading the dispersion solution on the surface of a liquid immiscible with the solvent to form a thin film, taking out the thin film, thereafter removing the solvent from the thin film, and pulverizing the thin film. The invention is useful for the formulation of a cosmetic.;COPYRIGHT: (C)2011,JPO&INPIT
