An aminoplast-curable film-forming composition is disclosed. The film-forming composition is a crosslinkable composition comprising (I) a material containing a plurality of carbamate and/or urea functional groups and (2) an aminoplast crosslinking agent. The composition provides a coating with improved acid etch resistance, making the coating particularly useful as an automotive clear coat.
L'invention concerne une composition filmogène durcissable à l'aminoplaste. La composition filmogène est une composition réticulable comprenant (1) un matériau contenant une pluralité de groupes fonctionnels de carbamate et/ou d'urée, et (2) un agent de réticulation à base d'aminoplaste. La composition produit un revêtement dont la résistance à l'attaque de l'acide est améliorée, ce qui permet de l'utiliser notamment comme couche de revêtement transparente pour automobile.
