Pigment Information
This color contains the following pigments:
PR19-Quinacridone Red
PBr25-Benzimidazolone Brown
Pigment Name
PR19-Quinacridone Red
Pigment Type
organic, quinacridone
Chemical Formula
C20H12N2O2
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 colors are often expensive, because more pigment is required in the formulation.
Permanence
Quinacridone Red 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. Quinicridone pigments contain a compound found to be a skin, eye, and respiratory irritant.
History
Although quinacridone compounds became known in the late 19th century, methods of manufacturing so as 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.
Pigment Name
PBr25-Benzimidazolone Brown
Pigment Type
organic, monoazo benzimidazolone
Chemical Formula
Properties
Benzimidazolone Brown is a transparent brown pigment that is heavily staining and dark valued but has moderately low tinting strength. According to its manufacturer Clariant, “It is a dark brown, very transparent benzimidazolone pigment with excellent light, weather, and solvent fastness properties plus high heat stability. Recommended for paste inks, solvent and water based packaging gravure, and flexographic printing inks.” Benzimidazolone Brown has been used in watercolor painting, where transparent brown colors have traditionally been mixed from other pigments.
Permanence
Benzimidazolone Brown has excellent lightfastness and weather resistance.
Toxicity
History
Benzimidazolone pigments were developed and patented by Hoechst in 1960, and have gradually come into use as artist pigments.
