Document Type and Number:
Japanese Patent JP2003128794
Kind Code:
A
Abstract:

To provide a method for coloring a highly heat-resistant resin, comprising kneading the highly heat-resistant resin having a high melt viscosity with a colored master batch formed from the same highly heat-resistant resin by the use of an injection molding machine, by which the highly heat-resistant resin can homogeneously be colored.

The colored master batch containing carbon dioxide in an amount of ≥0.3 wt.% is used.
