Abstract: A bismuth vanadate pigment is provided which pigment is doped with a combination of Mg, Al and P and optionally an element E, wherein the molar ratios of the Bi, V, Mg, Al, P and E correspond to a formula Bi Mga Alb Ec Vd Pe Of  (I) wherein E is selected from the group consisting of Be, Ca, Sr, Ba, Zr, Mo, Ce and a combination thereof; 0.001≦a≦0.2; 0.001≦b≦0.2; 0≦c≦1.7; 0.5≦d≦2.3; 0.001≦e≦0.5; and f denotes the number of oxygen atoms for satisfying the valence requirements of the cations. The pigment may be used as colorant in various applications, especially in coloring high molecular weight organic material, for example, coating compositions, paints, printing inks, liquid inks, plastics, films, fibers, or glazes for ceramics or glass.
