Abstract
PURPOSE: To obtain a polyester in which a pigment is well dispersed, by a method wherein a phosphorus compd. is added to a reaction mixt. in the manufacturing stage of the polyester, and a glycol ester contg. a pigment dispersed therein is added to the reaction mixt. within a specified time period after the addition of the phosphorus compd.
CONSTITUTION: A phosphorus compd. is added to a reaction mixt. in the manufacturing stage of a polyester. Then a glycol slurry contg. a pigment finely and uniformly dispersed therein is mixed with the reaction mixt. between 2 and 20min after the addition of the phoshorus compd. When the pigment slurry is added before lapse of 2min after the addition of the phosphorus compd., the agglomeration of the pigment due to the phosphorus compd. occurs. When the pigment slurry is added at a point at which more than 20min elapse after the addition of the phosphorus compd., the agglomeration of the pigment due to the temperature rise of the reaction system occurs. Thus, the uniform dispersion of the pigment in the polyester is not effected. Examples of the phosphorus compd. are phosphoric acid, phosphorous acid and esters thereof.
