Pigment Information

This color contains the following pigments:

PR176-Benzimidazolone Carmine

Pigment Name

PR176-Benzimidazolone Carmine

Pigment Type

organic, azo

Chemical Formula



Benzimidazolone Carmine is a staining, dull red transparent pigment with high tinting strength. Its color is similar to, although somewhat darker than, Rose Madder, the natural source of the historic color Alizarin Crimson. Because it stains and tints much more strongly than natural Rose Madder, care is required to achieve the same effects.


Although it is not absolutely lightfast, Benzimidazolone Carmine has excellent lightfastness for a transparent red organic pigment, and as a result, it is often chosen as a more permanent pigment to replace Alizarin Crimson.


Benzimidazolone Carmine is not considered toxic.


The benzimidazolone group of pigments was developed and patented in 1960 by Hoechst A.G., a German chemical manufacturer that was a forerunner of the pharmaceutical company Aventis. They differ very widely in hue.
