Description
A line of bright, transparent red synthetic azo-type organic pigments. Toluidine reds are based on the reaction of beta-naphthol with 2-nitro-4-toluidine. Toluidine red was first synthesized in 1904 by Lucius and Brüning in Germany. It reached its peak of popular use in the 1970s. In general, toluidine reds have fair lightfastness and weather resistance, but they have a tendency to bleed especially in oil paints. They are used in industrial coatings for air-dried and baked enamels and auto finishes. Toluidine reds are also used in wax crayons, pastels and watercolors.
