  • Acid etch resistant film-forming compositions and composite coating compositions
    Patent number: 6306505
    Abstract: A curable film-forming composition which is resistant to acid etching is provided. The curable film-forming composition comprises: A) a polymer prepared from the following ingredients: 1) an ethylenically unsaturated, beta-hydroxy ester functional monomer; 2) an ethylenically unsaturated, hydroxyalkyl functional monomer; 3) a vinyl aromatic compound; and 4) an alkyl ester of acrylic or methacrylic acid having 1 to 30 carbon atoms in the alkyl group; and B) an etherified aminoplast crosslinking agent. A multi-component composite coating composition is also provided, comprising a base coat deposited from a pigmented film-forming composition and a transparent top coat applied over the base coat in which the transparent coat, or clear coat, is deposited from the curable film-forming composition described above.
    Type: Grant
    Filed: August 18, 2000
    Date of Patent: October 23, 2001
    Assignee: PPG Industries Ohio, Inc.
