To obtain a polyolefin resin composition for powder coating, which uses polypropylene as a base polymer, is hardly colored even if it comes into contact with a colored liquid such as liquid colored foods including curry, ketchup, soybean sauce, sauce, butter, and the like, and is excellent in mechanical strength, elongation, heat resistance, and the like, and also in adhesion and durability, a powder therefor and a powder-coated article coated therewith.

The polyolefin resin composition for powder coating comprises (a) 100 pts.wt. of a random polypropylene, (b) 5-20 pts.wt. of an unsaturated carboxylic acid-modified polypropylene, (c) 5-20 pts.wt. of a polyethylene resin, and (d) 0.01-0.3 pts.wt. of a radical generator per 100 pts.wt. of the random polypropylene.
