Pigment Information
This color contains the following pigments:
PR23-Naphthol Carmine
PV19-Quinacridone Violet
Pigment Name
PR23-Naphthol Carmine
Pigment Type
organic, naphthol
Chemical Formula
Properties
Naphthol Carmine is a lightly staining, dull red pigment with a color similar to Rose Madder, the natural source of the historic color Alizarin Crimson.
Permanence
Naphthol Carmine has been reported to have inferior lightfastness compared to more modern sythetic pigments that replace it.
Toxicity
Although there have been no reports of acute toxicity, research has suggested that PR23 is genotoxic, and potentially mutagenic.
History
Naphthol Carmine was an early synthetic substitute for Rose Madder and Carmine. Before the late 19th centuries, reddish purple colors such as Alizarin Crimson, Tyrian Purple, and Carmine were available only from vegetable and animal sources. The manufacture and preparation of these colors was expensive. Clothing and textiles in these colors were considered a mark of affluence and distinction. Because Naphthol Carmine was far less expensive than the natural colors it replaced, it helped to create a revolution in color in the 19th century, as new color choices became available to the general population at affordable prices. These new sythetic dyes all but destroyed an industry in natural dyestuffs that had once employed thousands. Today, Naphthol Carmine has been largely superceeded by more permanent naphthol dyes.
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.
