Pigment Name: PV19-Quinacridone Violet

Pigment Type: organic synthetic, quinacridone

Properties

Quinacridone Red is a high-performance, transparent pigment with an average drying time and uneven dispersal. It is another name for Quinacridone Violet (PV19) and Quinacridone Red (PR192).

Quinacridone pigments have relatively low tinting strength in general. For this reason, quinacridone colours are often expensive because more pigment is required in the formulation.

Permanence

Quinacridone Violet has excellent lightfastness and is considered the most lightfast organic pigment in this shade range.

Toxicity

Quinacridone Violet has no known acute hazards. Overexposure to quinacridone pigments may cause skin irritation. Quinacridone pigments contain a compound found to be a skin, eye, and respiratory irritant.

History

Although quinacridone compounds became known in the late 19th century, manufacturing methods to make them practical for use as commercial pigments did not begin until the 1950s. Quinacridone pigments were first developed as coatings for the automotive industry but were quickly adopted by artists.
