PEARLY LUSTER PIGMENT AND COATING MATERIAL COMPOSITION, COSMETIC, INK AND PLASTICS BLENDED WITH THE SAME

摘要

PURPOSE: To obtain a pigment for a coating material, etc., by coating a synthetic mica having a smooth particle surface and an iron content equal to or lower than a specific value with a metal oxide, showing no yellow at a mass tone angle and a shade part, causing no faded color of an interference color. CONSTITUTION: A synthetic mica (e.g. tetrasilicon fluoride mica, etc.) containing Ti, Zn, Na, B, Li, Ca, Ge, Sr, Zr, etc., having <=1.58 average refractive index and <=1.0% iron content is mixed with water while stirring, blended with a solution of titanyl sulfate, rapidly heated to 100 deg.C, reacted at the temperature for 3 hours, filtered, washed with water and dried at 110 deg.C to give powder,, which is baked at 800 deg.C for 1 hour to give the objective pigment for a coating material, etc., by coating a synthetic mica which comprises the synthetic mica coated with a metal oxide (e.g. titanium dioxide, etc.), shows no yellow at a mass tone angle and a shade part, has solved the problem of a faded color of an interference color and is useful as a coating composition, cosmetic, ink, plastics etc.
