Cured coatings having particles at a surface region of the cured coating are provided. Also provided are multi-component composite coatings which include a cured basecoat deposited from a pigmented coating composition and a cured topcoat deposited from a topcoating composition. The multi-component composite coatings of the invention provide highly scratch resistant color-plus-clearcoatings capable of retaining scratch resistance after weathering.
L'invention concerne des revêtements durcis présentant des particules au niveau d'une région de surface du revêtement durci. L'invention concerne également des revêtements composites multiconstituants lesquels contiennent une couche de fond durcie déposée tirée d'une composition de revêtement pigmenté et une couche de finition durcie déposée tirée d'une composition de revêtement de finition. Les revêtements composites multiconstituants de l'invention procurent une couleur plus revêtements transparents hautement résistants à la rayure capables de conserver la résistance à la rayure après vieillissement climatique.
