Abstract
To solve the problems described herein, this invention provides a resin emulsion for primers capable of suitably controlling sagging when a base coating is applied and capable of obtaining a smooth appearance in aqueous paint systems for plastics. The invention provides an aqueous dispersion comprising an acid-modified polyolefin resin (A), a nitrogen-containing non-ionic emulsifier (B), and water, wherein the acid-modified polyolefin resin (A) is a propylene-α-olefin copolymer having a butene content of 2 to 35 mass % in a polyolefin component, and wherein a coating film after baking at 80° C. has a pure water contact angle of 40° to 90°.
