What is Pigment Red 266

Pigment Red 266 (C.I. 12475) is an organic pigment belonging to the naphthol AS pigment class. It generally produces a deep bluish-red shade and is used in a variety of industrial coloration systems such as coatings, plastics, and printing inks.

Pigment Red 266 is based on azo pigment chemistry, derived from naphthol AS coupling components that form stable colored compounds. Compared with some traditional monoazo pigments, Pigment Red 266 offers improved color depth and relatively balanced performance in different formulations.

Because of its deep red tone and adaptable properties, Pigment Red 266 is widely applied in industrial coloring processes where consistent red coloration is required.
