<p>A colored pigment master batch for use in blow molding containing a pigment and a carrier resin, characterized in that the carrier resin is a crystalline or amorphous thermoplastic elastomer which has a Vicat softening temperature higher than the melting point of a base resin for molding, a melting point of crystals or a temperature of start of flowing out being measured by a flow tester which is 20°C or more higher than the melting point of the base resin for molding, and an MFR which is 5 times that of the base resin for molding or greater; and a blow molding method, characterized in that a blow-molded article having an appearance like the grain of wood is produced using the colored pigment master batch. The colored pigment master batch is advantageous in that it provides a blow molding material the flash from which can be easily recycled as a part of a raw material.</p> |
