These are high performance organic red and violet pigments. Despite their high price, due to their outstanding light and weather fastness and solvent and migration resistance, they are used in high grade industrial coatings, automotive finishes, and special printing inks. Pigment Violet 19 (Figure 3.16) is the basic unsubstituted qui­nacridone molecule, which can exist in five crystal forms, but only two crystal forms are commer­cially important, p and y, which give violets and reds respectively.

Depending on type of substitution and crystal form, different qui — nacridone pigments with orange, maroon, scarlet, magenta and vio­let colors are available on the mar­ket. Some examples are Pigment Red 122, 192, 202, 207 and 209.
