In aluminum-based metal pigments produced by physical vapor deposition of a metal film and subsequent crushing of the metal film metal surfaces which are exposed after the operation of crushing the metal film and in particular fracture surfaces thereof are covered with a passivating protective layer to afford corrosion stability of those metal pigments.
Pigments métalliques à base d'aluminium produits par dépôt physique en phase vapeur d'un film métallique et broyage subséquent des surfaces du film métallique qui sont exposées après le broyage du film métallique et, en particulier, les surfaces de fracture sur celui-ci sont couvertes d'une couche protectrice de passivation pour procurer une bonne tenue à la corrosion de ces pigments métalliques.
