Abstract
An acid-modified polyolefin is dispersed in water by adding a hydroxy-functional ester made from a polymeric acid and a monoepoxide having from 14 to 46 carbon atoms to the water. Said dispersion is substantially zero-VOC. When a composition of this invention is applied to the surface and cured by baking the article at an elevated temperature, a coating is obtained which improves the adherence of subsequent coatings to a polyolefinic article. A polyolefinic article is one having a surface comprising polypropylene or a polypropylene modified with rubber called a thermoplastic polyolefin (TPO).
