<p>To provide a primer composition with which primer coatings can be formed which have excellent adhesion to metals such as iron or copper, or steel sheet plated with these, in particular zinc-plated steel sheet, and excellent adhesion to the top when polyamide (nylon) resins are used as the top coat, and, in particular excellent gasohol resistance. [Means of Solving Problem] A primer composition, characterized in that it contains (A) a polyamide imide resin, (B) nylon resin beads, (C) an epoxy resin, (D) a polyol resin and (E) a curing agent, and the percentage content of component (A) is 10 to 30 mass %, the percentage content of component (B) is 64 to 19 mass %, the percentage content of component (C) is 10 to 30 mass %, the percentage content of component (D) is 15 to 1 mass %, and the percentage content of component (E) is 1 to 20 mass %, relative to the total resin solids content of component (A), component (B), component (C), component (D) and component (E).</p> |
