THERMAL RESISTANT YELLOW WATER-CONTAINING IRON OXIDE PIGMENT AND MANUFACTURING METHOD THEREOF, COATING MATERIAL AND RESIN COMPOSITION USING THERMAL RESISTANT YELLOW WATER-CONTAINING IRON OXIDE PIGMENT

摘要

PROBLEM TO BE SOLVED: To provide a yellow water-containing iron oxide pigment having excellent thermal resistance and dispersibility, and to provide a simple manufacturing method thereof.SOLUTION: A thermal resistant yellow water-containing iron oxide pigment in which a particle surface of water-containing iron oxide particles are coated by a mixture containing aluminum silicate and a polymer compound can be produced by adding a mixture mainly containing a mixture of an inorganic compound mainly containing at least clay mineral and the polymer compound to an aqueous dispersion containing the water-containing iron oxide particles and treating them to form a layer of hydroxide of aluminum silicate.
