Oxidationsstabile Eisenoxidpigmente, Verfahren zu ihrer Herstellung sowie deren Verwendung
Oxidation stable iron oxide pigment (A) with an iron(II)-content of at least 5 wt.% (as iron(II)oxide) comprises an organic coating of a compound (I), where (A) exhibits an oxidation stability of >= 10[deg]C compared to non-coated iron oxide pigments, during oxidation stability test. Oxidation stable iron oxide pigment (A) with an iron(II)-content of at least 5 wt.% (as iron(II)oxide) comprises an organic coating of a compound (I) of formula XO aR 3> b(OR 2>) cR 1> d, where (A) exhibits an oxidation stability of >= 10[deg]C compared to non-coated iron oxide pigments, during oxidation stability test. X : Si, Sn, Ti, Zr, P or S; R 3>Cl, Br, NH 2 or OM; M : H, ammonium derivative, alkali metal, 1/2 alkaline earth metal, or 1/3 Al or 1/3 Fe; R 1>, R 2>1-15C-aliphatic (optionally saturated and optionally substituted by halo, NH 2, OH, NHR, NR 2, OR and/or R) or 4-26C-alicyclic, or 6-26C-aromatic (optionally substituted by NHR, NR 2, OR and/or R); R : 1-10C-aliphatic (optionally saturated) or 6-10C-alicyclic or aromatic (both optionally substituted); either a : maximum possible oxidation number of X, which is less than 4; and b : 0 to less than 8, which is the maximum possible oxidation number of X; and c, d : a whole number; or a+b+c+d : 4. An independent claim is included for a process to prepare the iron oxide pigment comprising mixing the iron oxide pigment with iron(II)-content (at least 5 wt.%, as iron(II)oxide) and (I) or a suspension or a paste containing (I), and then optionally drying and grounding the mixture.
