Abstract
PURPOSE: To prepare the titled composition giving a colored article free from color shading, by grinding powder of inorganic pigment, etc. and a powdery crushing medium in the presence of water or organic liquid in a crusher, thereby covering the surface of the nucleus originated from the powder with the fine particles originated from the medium.
CONSTITUTION: Powdery material which becomes the nucleus substance (e.g. inorganic pigment such as titanium white, red oxide, etc., metallic powder pigment, microballoon powder, plastic powder, etc.) and granular material used as a crushing medium (e.g.. calcined inorganic oxide pigment such as titanium white, red oxide, etc., plastic granules, etc.), are ground together with water or an organic liquid with a crusher such as centrifugal rotation ball mill, etc. The powder produced by the grinding action of the crushing medium is attached mechano-chemically to the whole surface of the nucleus substance, thereby giving the objective powder composition havig clear color.
