Abstract
PURPOSE: To prepare a colored polyester with excellent fastness, e.g. heat resistance, sublimation resistance, weather resistance, migration resistance, etc., by adding sulfonated phthalocyanine to a polyester as a coloring agent at a stage between the polymerization and the molding or fiber-forming of the polyester.
CONSTITUTION: A linear aromatic polyester consisting mainly of aromatic dicarboxylic acids (derivatives) having functional groups and glycols (derivatives) (e.g. polyethylene trreplthalste, etc.), is compound with 0.01-5wt.% of a sulfonated phthalocyanine exprssed by the formula (Pc is phthalocyanine residue; n is 1-4) as a coloring agent at an optional process from the production to the subsequent molding and processing. The coloring agent is also effecitive as a pigment dispersant for a poorly dispersible pigment, e.g. carbon black, cyanine blue, etc.
EFFECT: dispersible uniformly and finely.
