Although these heterocyclic azomethine-based high performance organic pigments have comparatively good light and weather fastness and solvent and migration resistance, very few of them are commercially available as pigments. They produce greenish to reddish-yellow hues and are used in high grade coatings and inks. Some widely known examples are Pigment Yellow 10 (Figure 3.14), 110 and 139.
