Acid Black 10b (widely classified as C.I. Acid Black 1, Chemical Index Number 20470, and chemically known as Amido Black 10B) is a prominent disazo dyestuff that dominates the industrial coloring market. Its unique molecular configuration—featuring complex aromatic diazo configurations coupled with H-acid (1-amino-8-naphthol-3,6-disulfonic acid)—renders it highly effective for substrate affinity across animal fibers, synthetics, and porous materials.
At Tianjin Sunrise Chem Group, our optimization of the synthetic roadmap for Acid Black 10b relies heavily on the diazotization of aniline and p-nitroaniline, coupled sequentially to H-acid under precise temperature and pH controls. By isolating reactive intermediates at a thermodynamic optimum (0-5°C), we consistently mitigate the generation of monoazo contaminants. The result is a highly concentrated, low-ash product that offers superior coloristic yields, clean solubility profiles, and unparalleled batch-to-batch consistency.

Unlike intermediate trading firms that republish generic datasheets, authentic primary manufacturers evaluate Acid Black 10b based on spectrophotometric reflectance curves and chromatographic separation (HPLC) profiles. Ensuring that salt by-products (such as sodium sulfate and sodium chloride) are systematically dialyzed allows procurement managers in the leather finishing and fingerprint forensic industries to avoid spotty deposition and precipitation.
The global commercial demand for Acid Black 10b stretches across numerous sectors. Because it functions effectively under acidic dyeing conditions (typically pH 4.0 - 5.5), it is the primary choice for fibers that require high exhaust rates and moderate-to-good wash and light fastness properties. Below, we break down how industries leverage this versatile compound:
In chrome-tanned and vegetable-tanned leather industries, Acid Black 10b provides deep chemical penetration into the dermic fibers. It masks collagen natural hues, ensuring a uniform, deep jet-black base that resists fading during buffing, dry milling, or polishing.
Particularly vital for wool, silk, and polyamide (nylon) fabrics. When blended with proper levelling agents, Acid Black 10b exhibits outstanding exhaustion curves, avoiding cross-staining and optimizing dyebath energy utilization.
Commonly utilized under the name Amido Black 10B, it is the primary dye used in forensic laboratories to visualize blood-contaminated latent fingerprints on porous and semi-porous surfaces. It stains protein residues a vibrant, high-contrast dark blue-black.
Finding a reliable, high-volume "Discount Acid Black 10b Manufacturer" is critical for reducing operational costs. In global markets, price fluctuations in raw petrochemical intermediates (aniline, nitrobenzene, naphthalene derivatives) can heavily impact the bottom line. By working directly with a primary synthesis factory like Tianjin Sunrise Chem Group, buyers eliminate third-party markup fees, guarantee continuous material access, and receive bespoke batch packaging tailored to their automated dosage systems.
Sustainable industrial colorants must balance fastness, solubility, and economic efficiency. Tianjin Sunrise Chem Group focuses on a strict technical roadmap:
Each production lot is subjected to rigorous testing against a retained standard batch using automated spectrophotometers. This ensures that when you choose Sunrise Chem Group as your long-term manufacturing partner, the Delta E value (color difference deviation) remains strictly under ≤ 0.5.
Below is our comprehensive portfolio of specialty acid dyes, direct colorants, solvents, and inorganic oxides manufactured at our primary facility, ensuring optimal performance for worldwide distribution.

Acid Black 10b (C.I. 20470 / Acid Black 1) is a synthetic chemical disazo molecular dyestuff that dissolves in aqueous solutions, coloring ionic substrates through electrostatic attraction and hydrogen bonding. In contrast, Carbon Black is a completely insoluble, amorphous carbonaceous pigment that requires resins, binders, and dispersants to mechanically adhere to the surface of materials.
Middlemen and localized trading suppliers do not control the synthesis pathway of aniline and H-acid. Sunrise Chem Group operates a vertically integrated production model. Since we synthesize major intermediates, purify the finished salt matrix, and manage logistics near Tianjin Port, we are insulated from intermediate trading markups, allowing us to guarantee consistent "discounted" pricing structures for high-volume contract buyers.
ZDHC (Zero Discharge of Hazardous Chemicals) Level 3 certification ensures that our chemical inputs, formulation processes, and byproducts are actively monitored and proven to contain zero traces of banned arylamines or carcinogenic intermediates. This allows global brands to pass customs audits, avoid product recalls, and maintain strict environmental compliance in North American and European markets.
Optimal dyeing exhaust occurs in a weak acid medium (pH range 4.5 to 5.5). The dye bath should be gradually heated to a boil (95-98°C) at a rate of 1-1.5°C per minute to ensure level distribution. Adding sodium sulfate (Glauber's salt) acts as an effective leveling agent to prevent uneven dye strike rates on highly crystalline nylon or wool proteins.
Yes, Sunrise Chem specializes in customized formulations. We supply highly stable liquid variations of our dyes for paper mills and continuous dyeing operations. These liquid forms prevent dusty environments, simplify dosing, and feature stabilizer compounds that prevent settling or crystallization during winter storage.
