Pigment Information

This color contains the following pigments:

PR179-Perylene Maroon

PR254-Pyrrole Red


Pigment Name

PR179-Perylene Maroon

Pigment Type

organic, anthraquinone

Chemical Formula

C26H14N2O4

Properties

Perylene Maroon is a transparent, dull to moderately dull, deep red pigment. Its transparency makes it useful as a glazing color.  Its mixing complement is Phthalo Green, and together they produce a pure black that is darker than most carbon-based pigments.

Permanence

Perylene Maroon has excellent permanence and lightfastness, and it can be an appropriate replacement for Anthraquinone Red in watercolor form.

Toxicity

Perylene Maroon has no significant acute toxicity. Its long term hazards are currently unknown.

History

Perylenes have been used as vat dyes since 1912, but they were not manufactured and sold as pigments until 1957.


Pigment Name

PR254-Pyrrole Red

Pigment Type

organic, aminoketone

Chemical Name

Bis-(p-chrolopheny)-1. 4-diketopyrrolo(3. 4-c)pyrrole

Chemical Formula

Properties

Pyrrole Red is opaque and has strong covering power. According to manufacturer Ciba, which uses the trade name Irgazin Red, it is a “clean, highly saturated mid shade red with high temperature resistance, excellent color strength, outstanding chemical, solvent and bleed resistance, and good weatherfastness.”

Permanence

Pyrrole Red is considered to have excellent lightfastness among organic pigments in its class. Tests in industrial applications have given it scores of 7-8 on the Blue Wool Scale.

Toxicity

According to the Australian government's Ministry on Health and Aging, "The notified chemical exhibited low oral and dermal toxicity in rats, did not exhibit toxic effects when administered orally to rats for 28 days, was not a skin irritant in rabbi

History

Pyrrole Red, used as an automotive paint and as a colorant in plastics, was developed as one of a range of pigments to replace lead based pigments. In art materials, it is often used as a synthetic and lightfast replacement for carmine, a laked pigment that was originally produced from the body of the cochineal insect. It is also used to replace the older naphthol reds, organic red pigments that are sometimes only marginally lightfast and weatherfast.
