Quick Summary

Quinacridone compounds are a group of synthetic pigments developed in the 20th century, with quinacridone itself introduced in 1958. These compounds exist in seven crystalline forms, offering colors from yellowish-red to violet. The violet (\beta) and red (\gamma) forms are particularly used as pigments, both classified as C.I. Pigment Violet 19.1

Pigments are insoluble materials that provide color by absorbing certain wavelengths of light and scattering others. Quinacridone reds are among the commonly used color pigments in paints and coatings. Dichloro and dimethyl analogs of quinacridone, substituted on each outer ring, are also commercially available as pink and bluish-red pigments.21
