Description

Benzoic acid, 4-[[1-hydroxy-6-[[[[5-hydroxy- 6-(phenylazo)-7-sulfo-2-naphthalenyl]amino]carbonyl ]amino]-3-sulfo-2-naphthalenyl]azo]-, compd. with α,α',α''- (nitrilotri-2,1-ethanediyl)tris[ω-hydroxypoly (oxy-1,2-ethanediyl)] (1:3) is a specialized, high-performance azo dye complex designed for demanding industrial applications. This compound matters because it offers enhanced solubility and stability in aqueous systems, a critical requirement for consistent coloration and performance in technical processes. It is primarily needed by manufacturers in the textile, ink, and specialty coatings industries seeking reliable and vibrant colorants for synthetic fibers and polymers.

Application

Textile Dyeing: Primary application for dyeing synthetic fibers such as polyamide (nylon) and polyester, providing excellent wash and light fastness.
Inkjet Inks: Used in the formulation of professional and industrial pigment-based inks, where color strength and dispersion stability are paramount.
Industrial Coatings: Imparts color to various polymer coatings and plastics, benefiting from its compatibility with polymeric systems.
Paper Coloring: Employed in specialty paper grades requiring specific, durable coloration.
Leather Finishing: Used in dyes and finishes for leather goods to achieve deep, uniform shades.
Masterbatch Production: A key colorant component in the production of plastic color concentrates for uniform tinting.
