从India供应商批量进口Acid Black 2

Acid Black 2 is a nigrosine-type acid dye with the Colour Index designation C.I. 50420 and CAS number 8005-03-6. Aryan Dyes & Pigments supplies this material from their location in Surat, Gujarat, as a powder suitable for leather, paper, wood, soap, anodized aluminium, wool, silk and ink manufacture.参照The supplier lists several trade synonyms including Acid Black 6RB, AACL Nigrosine WB, ABCOL Nigrosine 02P, Acid Black No 2, Acid Black WR and Acid Nigrosine, which buyers may encounter when cross-referencing technical literature or alternative sources. The stated minimum order quantity is 100 kg, with delivery to the buyer's specified destination.

The product is supplied as a dry powder, the standard physical form for acid dyes in bulk chemical trade. Nigrosine dyes such as Acid Black 2 are typically manufactured through oxidative coupling of aniline-derived intermediates, yielding a complex mixture of phenazine and induline structures that confer the characteristic deep black shade. The dye's solubility in water and acidic media, combined with its affinity for proteinaceous and anionic substrates, derives from sulfonic acid groups present in the molecular structure.，typical commercial grades exhibit water solubility of 10-50 g/L at 60°C, though buyers should request a Certificate of Analysis for the specific batch. Standard packaging for acid dye powders in Indian export trade is multi-layer polyethylene-lined fibreboard drums or woven polypropylene bags with moisture barrier liners, typically 25 kg net weight.

Leather tanneries represent the primary import market for Acid Black 2, using it for drum dyeing of vegetable-tanned and chrome-tanned hides to achieve uniform black shades on shoe uppers, garments and accessories. Paper mills apply it for deep black packaging and decorative papers; wood finishers use it for ebonizing hardwoods; soap manufacturers for coloured specialty bars. Anodized aluminium processors employ it for architectural and consumer goods finishes. Wool and silk dyers in textile-producing regions use it where deep black with moderate fastness suffices. Ink formulators value its high tinctorial strength and compatibility with aqueous vehicle systems.
