PV 19 – Quinacridone Violet is a synthetic organic pigment belonging to the quinacridone family, a class renowned for its exceptional lightfastness, chemical stability, and chromatic purity. PV 19 is characterized by a deep, cool violet hue with strong blue undertones, offering high color intensity and transparency, which make it particularly valuable in artistic and industrial applications where both vibrancy and permanence are required.

Chemically, PV 19 is based on the quinacridone molecular structure, which consists of fused aromatic rings with carbonyl and nitrogen groups that provide outstanding resistance to light, heat, and solvents. This robust molecular framework ensures excellent chemical stability in paints, coatings, inks, and plastics. Unlike inorganic violet pigments, PV 19 combines high chromatic brilliance with a durable, organic composition, making it a preferred choice for modern, high-performance colorants.

In artistic use, Quinacridone Violet exhibits strong tinting strength and a transparent character, which allows for glazing, layering, and nuanced color modulation. It mixes cleanly with whites, blues, and other reds to create a wide range of purples, mauves, and cool pinks. Its transparency also enables subtle layering techniques that are difficult to achieve with more opaque pigments.
