1.Product Description
Achieve Brilliant Blue-Shade Reds with Acid Red 249 – The Premier Milling Acid Dye for High-Performance Textiles.
Acid Red 249, widely recognized as Weak Acid Brilliant Red B or Tracid Brilliant Red B, is a distinguished monoazo dye engineered specifically for applications demanding superior wet fastness combined with brilliant, clean red shades. Its sophisticated molecular architecture, featuring a complex sulfonated naphthalene core with chloro-phenoxy and tolylsulfonylamino substituents, creates a larger molecular structure characteristic of milling-type acid dyes.
What truly distinguishes Acid Red 249 is its exceptional balance of leveling and fastness properties. The dye exhibits a distinctive bluish-red shade with maximum absorption at 523 nm in aqueous solution, producing vibrant, clean reds with excellent brightness. Its weak acid character allows for controlled exhaustion on protein and polyamide fibers while maintaining the high wet fastness required for apparel, swimwear, and upholstery applications.
The dye demonstrates remarkable stability in acidic dye baths (pH 4.5-5.5 recommended) and maintains consistent performance in the presence of metal ions, with no adverse effects on shade development. Available in dark red powder form, it offers excellent water solubility (50 g/L at 90°C) and builds uniformly to achieve deep, saturated shades.
For leather finishing, Acid Red 249 provides deep penetration and brilliant coloration on finished leathers and wet-blue stocks. Its application extends to paper dyeing, ink manufacturing, and the production of lake pigments, demonstrating true multi-industry versatility.
