Pigment Information

This color contains the following pigments:

PO48-Quinacridone Gold

PY180-Benzimidazolone Yellow


Pigment Name

PO48-Quinacridone Gold

Pigment Type

organic, quinacridone

Chemical Formula

C20H12N2O2 or C20H10N2O4

Properties

Quinacridone Gold is a high performance pigment. It lacks brightness and cleanliness in tints, and it may disperse unevenly. It has an 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 Gold has excellent lightfastness and is considered the most lightfast pigment in its shade range.

Toxicity

Quinacridone gold is not considered toxic. 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

PY180-Benzimidazolone Yellow

Pigment Type

organic, benzimidazolone

Chemical Formula

Properties

Benzimidazolone Yellow 180 is a transparent greenish yellow pigment with high tinting strength. It is very similar in hue to PY74, a Hansa Yellow pigment with even higher tinting strength that was the traditional yellow used in CMYK (four color) process printing.

Permanence

Pure tones of Benzimidazolone Yellow 180 have excellent lightfastness. Tints with white are considered less lightfast. Benzimidazolone Yellow 180 is considered to have greater lightfastness than PY74, which it often replaces in printing technology.

Toxicity

Benzimidazolone Yellow 180 is not considered toxic.

History

Benzimidazolone pigments were developed by Hoechst in the 1950s and 1960s. Benzimidazolone Yellow 180 is used in printing and plastics. Although it is more expensive than PY74, a Hansa Yellow, and has lower tinting strength, its lightfastness often makes it the yellow of choice in four color process printing.
