Pigment Information

This color contains the following pigments:

PR209-Quinacridone Red

PR48:4-Permanent Red


Pigment Name

PR209-Quinacridone Red

Pigment Type

organic, quinacridone

Chemical Formula

Properties

Quinacridone Red is a bright, clean red pigment with average drying time. 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 permanence and lightfastness.

Toxicity

Quinacridone Red 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

PR48:4-Permanent Red

Pigment Type

organic, monoazo

Chemical Name

beta-oxynaphthoic acid lake, manganese salt

Chemical Formula

Properties

Permanent Red is a common name used for the manganese salt of beta-oxynaphthoic acid (BONA) lake pigment PR:48. It is more blue than other shades of PR:48, with the exception of PR48:2. BONA pigment lakes have high tinting strength.

Permanence

Beta-oxynaphthoic acid (BONA) lake pigments are more lightfast than their beta-naphthol counterparts. Although their lightfastness makes them the pigment of choice in many applications, they may shift slightly in color or lose intensity under some conditions. Pigment PR48:4 is considered more  lightfast and durable than other PR48 salts.

Toxicity

History

Beta-oxynaphthoic acid may have been synthesized as early as 1887. Commerical use of BONA lake pigments began in the 20th century. Pigment PR48:4 is used in packaging and plastics.
