Abstract
PURPOSE: To prevent color non-uniformity from occurring during molding, by compounding a coloring composition consisting of a polybutylene terephthalate resin and a colorant with a finely powdered inorg. material essentially comprising silicon oxide and magnesium oxide.
CONSTITUTION: 100pts.wt. polybutylene terephthalate resin (A), about 0.01W 5pts.wt. pigment or dye (B) such as an azo or phthalocyanine dye or pigment, titanium dioxide or carbon block, and about 0.1W2pts.wt. additive for preventing color non-uninformity (C) such as a talc of the formula Mg3SiO4O10(OH)2 consisting of about 50W70wt% silicon oxide and about 50W30wt% magnesium oxide are mixed to prepare the titled colored composition. The componente many contain Al2O3, Fe2O3, CaO, etc. A molded product having a uniformly colored surface is obtd. by molding the obtd. colored composition.
