Pigment Information

This color contains the following pigments:

PR23-Naphthol Carmine

PR112-Naphthol Red AS-D


Pigment Name

PR23-Naphthol Carmine

Pigment Type

organic, naphthol

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

PR112-Naphthol Red AS-D

Pigment Type

organic, monoazo

Chemical Formula

C24H16Cl3N3O2

Properties

This Naphthol Red is an intense scarlet red pigment that is heavily staining. It has an average drying time. It is semi-transparent and has relatively poor covering power.

Permanence

This Naphthol Red has been rated as having excellent lightfastness under ASTM testing, but other testing methods have demonstrated some tendancy for the color to fade with exposure to strong ultraviolet light. It has been considered a replacement for less lightfast naphthol reds such as PR3. Not suitable for exterior use.

Toxicity

Naphthol Reds are not considered toxic. Naphthol Red AS-D may cause eye, skin, or respiratory irritation. Contact with dry pigment should be avoided.

History

Unknown.
