An object of the present invention is to provide a primer / base coating composition that does not require the use of a primer coating layer in a multilayer coating for automobile interior parts. SOLUTION: Blocked with an acrylic resin (A-1) having a hydroxyl value of 40 to 120 mgKOH / g, a chlorinated polyolefin resin (A-2), an acrylic-modified chlorinated polyolefin resin (A-3), and a blocking agent. A base coating composition containing a polyisocyanate curing agent (A-4) which is a polyisocyanate compound, comprising (A-1), (A-2), (A-3) and (A-4) The amount of the acrylic resin (A-1) is 40 to 65% by weight, the amount of the chlorinated polyolefin resin (A-2) is 5 to 18% by weight, and the acrylic modified chlorinated polyolefin resin is based on the total weight. A base coating composition having an amount of (A-3) of 20 to 30% by weight. [Selection figure] None |
