Abstract
A water-borne primer coating composition including a water-borne non-chlorinated polyolefin resin (A), a water-borne polyurethane resin (B), a water-borne epoxy resin (C) and an internally crosslinked acrylic particle emulsion (D), wherein the content of resin (A) is 15 to 60%, the content of resin (B) is 10 to 50%, the content of resin (C) is 20 to 50%, and the content of emulsion (D) is 5 to 20%, all by weight on the solid equivalent basis in 100% by weight of the total amount of resin (A), resin (B), resin (C) and emulsion (D), and resin (A) is a polypropylene resin having crystallinity of 35 to 55% and a weight average molecular weight of 50000 to 200000. The composition can achieve an adhesion property to a substrate, gasohol resistance, inhibition of peeling of a multilayer coating film in washing by high pressure cleaning and moisture resistance.
