Abstract

PURPOSE: To provide a pigment compsn. which is useful for polyesters, is inexpensive and excels in hiding properties, whiteness and tinting, consisting of titanium white and a calcium carbonate pigment on the surface of which polyethylene glycol, is adsorbed.
CONSTITUTION: Polyethylene glycol is added to a suspension of calcium carbonate. Mixing is carried out to obtain a uniform mixt. The mixt. is dehydrated, dried and powdered to obtain a calcium carbonate pigment (A) on the surface of which 0.2W20.0pts.wt. of polyethylene glycol per 100pts.wt. of calcium carbonate is adsorbed. Then 1W30pts.wt. of (A) is mixed with 70W90pts.wt. of titanium white (B) to obtain titled pigment compsn. Said pigment compsn. is dispersed in the etylene glycol as the starting material of a polyester. The resulting material together with a catalyst is added to a reaction medium. The mixt. is subjected to polycondensation to obtain a polyester compsn. contg. the pigment compsn. dispersed therein.
