摘要 |
The invention is concerned with stabilized metal pigments, in particular aluminum pigments, particularly against water and moisture, with improved resistance characteristics in aqueous paints. The stabilization of the metal particles is carried out through treatment with carboxyalkylene phosphoric acid esters, and/or carboxyalkylene phosphonic acids, and/or carboxyalkylene phosphinic acids. The carboxylic group of the compounds can be at least partially neutralized if desired. |
