Abstract

Abstract Described is a coating composition comprising a liquid medium containing a titanium dioxide pigment and a coating film formation resin said titanium dioxide pigment being in the form of flaky or fin-like small pieces of silicon dioxide covered by titanium dioxide and having a diameter of 1 to 300 microns and a thickness of 0.001 to 1 micron, a considerable portion of said silicon dioxide being dissolved out from said titanium dioxide-coated silicon dioxide small pieces.
