Organic and Inorganic Pigments

Pigment Black 26 (C.I. 77494) is a black mixed oxide of manganese (II) and iron (III) with chemical formula MnFe2O4 and a spinel structure. It provides a very deep bluish black shade and is the strongest black CICP.

PBk23 (C.I. 77865) is a grey pigment with chemical formula (Sn,Sb)O2 and a cassiterite structure. It provides a grey shade.

Pigment Black 12 (C.I. 77543) is a buff mixed oxide of iron (II) and titanium (IV) with chemical formula Fe2TiO4 and a spinel structure. It provides a buff shade, similar to PBr24, without containing Cr3+.

Pigment Black 11 (C.I. 77499) is a black iron oxide with chemical formula Fe3O4 and a magnetite structure.

Pigment Brown 29 (C.I. 77500) is a complex inorganic pigment of black mixed oxide of iron (III) and chrome (III) with chemical formula (Cr, Fe)2O3 and a hematite structure. It is a brownish to bluish black pigment.

Pigment Brown 33 (C.I. 77503) is a brown mixed oxide of zinc (II), iron (II, III) and chrome (III) with chemical formula (Zn,Fe)(Fe,Cr)2O4 and a spinel structure. It provides a brown shade.

Pigment Brown 24 (C.I. 77310) is a buff chrome titanate complex inorganic pigment with a chemical formula of (Ti,Cr,Sb) O2 and rutile lattice (tetragonal) structure.

Pigment Red 104 (C.I. 77605) is an orange-red lead chromate-molybdate with chemical formula PbCrO4.PbSO4.PbMoO4 and a tetragonal structure.
