PROBLEM TO BE SOLVED: To obtain a resin composition which can give an injection molding made proof against white streaks and color unevenness otherwise occurring on its surface and not undergoing deterioration in physical properties and defects such as silver streaks by mixing a polyolefin resin with a specified amount of an unmodified polyethylene glycol having a specified or higher molecular weight and a pigment. SOLUTION: The polyolefin resin (100 pts.wt.)is mixed with 0.03-5.0 pts.wt. unmodified polyethylene glycol having a weight-average molecular weight of at least 1,200. The polyolefin resin is desirably a mixture having a polyethylene/ polypropylene weight ratio of 0/100 to 50/100. The unmodified polyethylene glycol is desirably one having a weight-average molecular weight of 1,500-10,000 and the number of moles of ethylene oxide added of at least 40. The pigment used is desirably a pigment containing a titanium pigment.
