Acid Brown DT and Acid Brown NT are synthetic acid dyes used for colouring wool, silk, cotton, and leather, with Acid Brown 282 as a reference variant. These dyes are water-soluble and provide deep, consistent brown shades for textile and leather applications. The product is also employed in printing processes, particularly for black silk ribbon, where it delivers uniform colour penetration and fastness.

The dyes belong to the acid class, which bonds ionically with protein and polyamide fibres under acidic conditions. Acid Brown DT and NT share synonyms such as Akacid Brown GRS 150%, Dorolan Brown SGR 150%, and Intralan Fast Dark Brown GR-W, indicating their widespread use in industrial formulations. Typical dye content for acid brown variants ranges between 30% and 50%, with purity levels standard for textile-grade applications. The powder form is the most common, offering ease of handling and dissolution in dye baths.
