Pigment Information

PBk11-Mars Black
PR3-Toluidine Red
PV23-Dioxazine Violet
PV19-Quinacridone Violet
Pigment Name
PBk11-Mars Black
Pigment Type
earth
Chemical Name
iron oxides
Chemical Formula
FeO or Fe2O3
Properties
Mars Black is an opaque black with a strong and cool masstone, a slightly warm tint, and a warm brown undertone. It is not as black as Ivory Black, but it dries more quickly and has three times the tinting strength. Mars Black is normally the only black available in acrylic form and that is safe to over paint. It can be used in all media without reservation and is widely used as an alternative to Lamp Black and Ivory Black.
Permanence
Mars Black is very lightfast with excellent permanence.
Toxicity
Mars Black has no significant hazards and is the only major black pigment considered non-toxic.
History
The word Mars refers to the Roman god of iron and war. Mars Black was developed in the early 20th century from inorganic, synthetic iron oxide.
Pigment Name
PR3-Toluidine Red
Pigment Type
organic, monoazo
Chemical Formula
Properties
Toluidine Red is a semi-opaque, yellowish red pigment with high tinting strength.
Permanence
Toluidine Red has very good lightfastness.
Toxicity
Toluidine Red is not regarded as toxic.
History
Toluidine Red or Toluidine Scarlet has been used in inks, textiles, artist materials, and plastics.
Pigment Name
PV23-Dioxazine Violet
Pigment Type
organic
Chemical Name
carbazole dioxazine
Chemical Formula
C34H22Cl2N4O2
Properties
Dioxazine Violet is transparent and has very high tinting strength. It is a staining pigment, very dark valued when it is used at full strength. Concentrated, it paints out nearly black, but it mixes with Titanium White to form bright, opaque tints of purple. PV23 produces slightly redder shades than PV37. Because the hue can vary with the conditions of preparation and grinding, it may be offered in red shade, blue shade, and so forth.
Permanence
Dioxazine Violet has good lightfastness. There may be some concern about it fading or shifting in color in tints and washes. Some artists have reported that PV37, a molecular variant, is more lightfast than PV23.
Toxicity
History
Two molecular variants of Dioxazine Violet, PV23 and PV37, are available. They have similar properties, but mix slightly differently.
Pigment Name
PV19-Quinacridone Violet
Pigment Type
organic synthetic, 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 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. 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.
