PR221-Condensed Azo Pigment
organic, condensed disazo
PR221 is a transparent bluish-red pigment with high tinting strength compared to other transparent bluish-red pigments. Although its hue is not a perfect match, it is one of several newer red pigments that is being used to replace traditional fugitive colors such as carmine and alizarin crimson.
PR221 has very good permanence and lightfastness, but is not as resistant to fading as the quinacridone pigments.
Industrial processes for manufacturing condensed disazo pigments were developed by CIBA in the 20th century.
PR209-Quinacridone Red
organic, quinacridone
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.
Quinacridone Red has excellent permanence and lightfastness.
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.
