摘要 |
<p>The present invention relates to ; 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: (A) 15-92 % by weight of a crystalline propylene-ethylene block copolymer resin, (B) 5-40 % by weight of an ethylene-propylene copolymer rubber, (C) 1-15 % by weight of a hydroxyl group-containing propylene oligomer, and (D) 2-30 % by weight of an inorganic filler; 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 a paint-coated article obtained by said method for paint-coating the polypropylene resin composition molded article. The methods for surface treating and paint-coating the polypropylene resin composition molded articles according to the present invention give excellent paint-coatability and adhesion properties to said molded articles, and the paint-coated article obtained by said methods is useful and suitable especially for automotive exterior parts such as a bumper or an instrument panel.</p> |
