Abstract
The present invention relates to; PA1 a method for surface treating a polypropylene resin composition molded article, which comprises irradiating a molded article with ultraviolet light having an irradiation wavelength of 300 nm or less, said molded article being obtained from a polypropylene resin composition which comprises: PA0 (A) 15-92% by weight of a crystalline propylene-ethylene block copolymer resin, PA0 (B) 5-40% by weight of an ethylene-propylene copolymer rubber, PA0 (C) 1-15% by weight of a hydroxyl group-containing propylene oligomer, and PA0 (D) 2-30% by weight of an inorganic filler; PA1 a method for paint-coating a polypropylene resin composition molded article, which comprises irradiating a molded article with ultraviolet light having an irradiation wavelength of 300 nm or less and coating the irradiated surface with a paint, said molded article being obtained from a polypropylene resin composition which comprises said components (A), (B), (C) and (D) above-mentioned; and PA1 a paint-coated article obtained by said method for paint-coating the polypropylene resin composition molded article. According to the present invention, the methods for surface treating and p…
