Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an oxidation-stable iron(II)-containing iron oxide pigment which has good oxidation stability, at least comparable with that of boron-containing iron oxide pigments, and can be prepared through a single step by using commercially available ordinary organic substances without use of inorganic substances.SOLUTION: An oxidation-stable iron oxide pigment has a content of iron(II) of 5 mass% or higher, based on FeO, and an organic coating of at least one organic substances of formula R-(COOX)n. 【課題】酸化安定性がホウ素含有酸化鉄顔料と少なくとも同程度に良好であるが、無機物質を使用せずに市販されている通常の有機物質を使用して一工程で調製可能である酸化安定性鉄（ＩＩ）含有酸化鉄顔料を提供する。【解決手段】ＦｅＯとして計算したときに少なくとも５重量％の鉄（ＩＩ）含量を有し、かつＲ−（ＣＯＯＸ）ｎで示される少なくとも１種の有機物質の有機コーティングを有する酸化安定性酸化鉄顔料と、その調製とその使用。【選択図】なし
