COMPOSITE ARTICLES HAVING EXCELLENT ADHESION STRENGTH AND METHODS OF FORMING THE SAME

摘要

A composite article generally comprises a substantially transparent outermost layer, a tie-layer, and a backing layer. The composite article can also include a substrate layer. The tie-layer imparts excellent adhesion strength between the substantially transparent outermost layer and the backing layer. The outermost layer is formed from a coating composition, e.g. a clearcoat paint composition, and can optionally be tinted. The tie-layer is formed from an adhesion promoting composition comprising a halogenated polyolefin, such as chlorinated polyolefin (CPO), and optionally, a solvent, such as an organic solvent. The backing layer is formed from a metal composition, such as chrome. If employed, the substrate layer is typically formed from a plastic, such as acrylonitrile butadiene styrene. The composite articles of the present invention may be used for various applications, such as for automobile parts and trim. The composite article can have an imparted aesthetic effect, such as being pewter in color.
