PROBLEM TO BE SOLVED: To provide a master batch composition from which resin molded articles having excellent and little fluctuated mechanical physical properties can be produced, and to provide a method for producing the resin molded article. SOLUTION: This master batch composition is characterized by comprising 20 to 60 pts.wt. of propylene resin having a melt flow rate (MFR) of 20 to 80 g/10 min, (B) 80 to 40 pts.wt. of talc having an average particle diameter of 2 to 6μm, and (C) a metal soap in an amount of 0.01 to 5 pts.wt. per 100 pts.wt. of the polypropylene resin and the talc. The master batch composition has a pellet shape having an average pellet diameter of 2 to 6 mm and an average pellet diameter irregularity of≤2.0. COPYRIGHT: (C)2003,JPO |
