PROCESS FOR FORMATION OF COATING FILM ON PLASTIC MATERIAL AND COATED ARTICLE

摘要

The present invention provides: a process for formation of a coating film on a plastic material, which process enables formation of the coating film with good productivity wherein the coating film is excellent in the adhesion, the humidity-resisting adhesion, and the gasohol resistance, and has good appearance; and a coated article. The process for formation of a coating film on a plast ic material is a process for formation of a coating film, which process compris es the steps of: coating the plastic material with a specific aqueous primer coatin g composition; and thereafter drying the resultant primer coating film in such a manner that its nonvolatile content will not be less than 70 weight %; and thereaft er overcoating the primer coating film with a specific aqueous base paint composition; and thereafter drying the resultant base coating film in such a manner that its nonvolatile content will not be less than 60 weight %; and thereafter overcoating the base coating film with a two-component clear paint; and thereafter baking th e resultant three-layered coating film onto the plastic material.
