Abstract
A method for producing flaky materials useful for improving, for example, a spreadability and luster of cosmetics and paints or improving mechanical characteristics of plastics, which comprises coating the liquid sol of metallic compounds onto a smooth surface to form a coated film; solidifying the said film into gel by means of heating, pH control, hydrolysis or vaporization-removal of a part of the dispersion medium; shrinking the volume of the said film by further vaporization-removal of the dispersion medium from the film; and then scraping off the flaky material from the smooth surface.
