Description
A class of bright cherry-red synthetic organic colorants. Para red was first synthesized in 1880 by Holliday in England. The dye is made by reacting beta-naphthol with Paranitroaniline, a coal-tar derivative. Different shades are obtained by varying temperature and pH of the mixture. Para reds have fair lightfastness and are not used in artists paints because of bleeding. They were previously used industrially in metal finishes and printing inks but have been replaced with more durable colors.
Synonyms and Related Terms
paranitraniline red; Pigment Red 1; CI 12070; p-nitrobenzene-azo-beta-naphthol; Pararot (Deut.); rouge para (Fr.); pararood (Ned.); Signal red; para toner;
