CA 2294942

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 cross-linking 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.

L'invention concerne une composition filmogène durcissable, qui résiste à l'attaque des acides. Ladite composition filmogène comprend: A) un polymère préparé à partir des ingrédients suivants: 1) un monomère fonctionnel de bêta-hydroxyester, éthyléniquement insaturé; 2) un monomère fonctionnel hydroxyalkylique, éthyléniquement insaturé; 3) un composé aromatique vinylique; et 4) un alkylester d'acide acrylique ou méthacrylique ayant 1 à 30 atomes de carbone dans le groupe alkyle; et B) un agent de réticulation aminoplaste éthérifié. L'invention porte aussi sur un composite de revêtement à composants multiples, comprenant une couche de base déposée par une composition filmogène pigmentée et une couche supérieure transparente appliquée sur la couche de base, la couche transparente ou translucide étant déposée par la composition filmogène durcissable de l'invention.
