| 摘要 |
This invention provides a water-based primer composition comprising (A) an aqueous dispersion of modified polyolefin, (B) an aqueous urethane resin and/or aqueous acrylic resin, (C) a pyrazole-blocked polyisocyanate compound and (D) an electrically conducting pigment, its (C) pyrazole-blocked polyisocyanate compound content being within a range of 5-50 mass % based on the total solid content of the components (A), (B) and (C), said electrically conducting pigment (D) containing an electrically conducting metal oxide (D-1), and the content of the electrically conducting pigment (D) being within a range of 50-200 mass parts per 100 mass parts of the total solid resin content in the composition; and also methods for coating plastic shaped articles using the composition. |
