Abstract

La présente invention vise à fournir : une composition de revêtement par électrodéposition cationique qui présente d'excellentes propriétés anticorrosion et d'aptitude au finissage sur une partie de bord et une partie plate ; et un article revêtu qui présente les excellentes performances d'un film de revêtement telles que mentionnées ci-dessus. Comme moyen de résolution du problème, l'invention porte sur une composition de revêtement par électrodéposition cationique qui comprend une résine époxy (A) contenant un groupe amino, un composé polyisocyanate bloqué (B), un composé polymère polaire (C) et des particules (D), ladite composition de revêtement par électrodéposition cationique étant caractérisée en ce que les particules (D) contiennent un minéral argileux (D1) et/ou des particules de résine réticulée (D2).
