Abstract
PURPOSE:To obtain the titled pigment having excellent light resistance and weather resistance, causing slight change of color even by outdoor exposure for a long period of time, by coating the surface of flaky mica-shaped particles of iron oxide crystal with titanium dioxide, covering the coated surface with a layer comprising a hydrous oxide of chromium and burning. CONSTITUTION:The surface of flaky mica-shaped particles of iron oxide crystal is coated with titanium dioxide (e.g. rutile structure) and then covered with 0.001-1.0wt.% (based on iron oxide pigment coated with titanium dioxide) coated amount of hydrous oxide of chromium, vanadium molybdenum or aluminum alone or a combination of two or more, burnt and subjected to after- treatment to give the aimed pigment having improved water resistance and weather resistance and beautiful color tone.
