ABSTRACT:
A composition comprising a chlorinated polyolefin and an optical brightener is disclosed. The compositions are useful as detectable adhesion promoters for polyolefin substrates. The compositions are applied as a coating to the polyolefin substrate and the coated substrate exposed to an ultraviolet light source to determine uniformity of the coating over the substrate. Uniform coverage is necessary to develop optimum adhesion between the substrate and a subsequently applied paint layer.
