Abstract: Blue iron hexacyanoferrate-III pigments (I) are prepared by anodic oxidation of metallic iron in hydrogen cyanide, or a reaction medium containing hydrogen cyanide, at pH 8. The process gives readily dispersible pigments (I) which are of high color strength and give brilliant, glossy colorations.
