Abstract
Polyurethane articles of manufacture are treated so as to make their surfaces more adherent to paint by contacting the surfaces of the articles with a solution of phosphoric acid in a low molecular weight organic solvent, e.g. a carboxylic acid ester such as ethyl acetate. The treated article is then dried at an elevated temperature.
