Title:
COLORING PIGMENT MASTERBATCH COMPOSITION AND METHOD OF MOLDING
Document Type and Number:
WIPO Patent Application WO/2003/033572
Kind Code:
A1
Abstract:
A pigment masterbatch composition which comprises a specific thermoplastic elastomer, a specific thermoplastic resin, and a pigment. It can develop a colored clear wood grain and can effectively inhibit the pinch−off part strength or impact strength from being reduced by wood grain formation. The composition can be molded not only by blow molding but by injection molding or extrusion molding. Even when recycle materials containing a pigment are molded, the composition can diminish influences of base color differences to thereby reduce the rate of rejected products due to a color difference.
