Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a metal pigment which exhibits improved stability even in an extremely invasive condition such as high pH, and a production method and use of the same.SOLUTION: A metal pigment has a metal substrate and coating, in which the coating comprises at least one first coating layer surrounding the metal pigment containing at least one metal oxide, and at least one second coating layer containing at least one heteropolysiloxane, here the term metal oxide also includes oxide hydrates and hydroxides, the at least one heteropolysiloxane has at least one aminosilane component and at least one silane component selected from a group composed of alkylsilanes, vinylsilanes, and arylsilanes, and the heteropolysiloxane is applied in a precondensed form to the at least one first surrounding coating layer.SELECTED DRAWING: None 【課題】高いｐＨなどの非常に侵略的な条件下でも、改善された安定性を示す金属顔料、及びそれを製造するための方法、その使用を提供する。【解決手段】金属基材および被覆を有する金属顔料であって、被覆が、少なくとも１種の金属酸化物を含有する金属顔料を包囲する少なくとも１つの第１の被覆層、及び少なくとも１種のヘテロポリシロキサンを含有する少なくとも１つの第２の被覆層を含み、ここで、金属酸化物という用語には、酸化物水和物および水酸化物も包含され、少なくとも１種のヘテロポリシロキサンが、少なくとも１種のアミノシラン構成要素と、アルキルシラン、ビニルシラン、およびアリールシランからなる群から選択される少なくとも１種のシラン構成要素とを有し、ヘテロポリシロキサンが、事前縮合形態で、少なくとも１つの第１の包囲被覆層に施与されている。【選択図】なし
