Descrizione

Direct Red 79 is a red fluorescent dye that is used in textile and leather production, paper coating, and for coloration of paper. It is also used in the production of optical brighteners, which are reactive compounds that absorb light and then emit light of longer wavelengths. Direct Red 79 is synthesized by the condensation reaction of acetyl chloride with o-aminophenol. The product has an absorption maximum at 603 nm and a fluorescence emission maximum at 659 nm. This dye reacts with copper complexes to produce a blue light emission when excited with ultraviolet radiation.
