Abstract
PURPOSE: To color a synthetic resin uniformly with a high tinting strength without reducing the dimensional stability of a molded article, by using a coloring agent consisting of an organic pigment and an inorganic compound having a chemical structure like spinel.
CONSTITUTION: An organic pigment, e.g. copper phthalocyanine pigment, is uniformly mixed with an inorganic compound, e.g. spinel (MgO.Al2O3), having a chemical structure like spinel in a mixer. The treated pigment is then mixed with a synthetic resin, e.g. polyethylene, and if necessary an additive, e.g. zinc stearate, in a tumbler, and the resultant mixture is molded by an injection molding machine, etc. The amount of the inorganic compound is preferably 2W10pts.wt. based on 1pt.wt. organic pigment.
