Applications of 1-Amino-5-Benzoylaminoanthraquinone in Industrial Manufacturing

As a specialized manufacturer of 1-Amino-5-Benzoylaminoanthraquinone, we supply this advanced anthraquinone derivative to global industrial customers. The material demonstrates unique color strength and stability, making it critical for multiple downstream chemical sectors. Below we outline the main real-world industrial applications based on direct customer production needs and regulatory requirements.

1. Polyester Fiber Spinning Colorants

Polyester fiber producers use this anthraquinone-based dye intermediate to achieve stable and high-grade red hues. Its molecular structure ensures dye fastness against washing, light, and sublimation, which is essential in high-temperature spinning environments. Manufacturers refine additive concentrations to balance intensity and migration resistance, especially for colored filament and staple fiber production. Careful QMS documentation tracks every batch to satisfy automotive and apparel sector traceability.

• Dispersed into varnish carrier during ink let-down
• Tested via QC drawdowns for chromatic stability before shipment

Final product types

• Flexible packaging inks for food and beverage
• Security inks for official documents
• Commercial offset/coldset inks for catalogs
• Industrial marking and coding inks

3. Engineering Plastics Color Masterbatch

Compounders utilize this anthraquinone derivative in the coloration of engineering plastics requiring UV stability and heat resistance.

• Colored appliance parts

4. Synthetic Leather and PU Coating Dyes

Producers of synthetic leather and polyurethane coatings select this raw material for its resistance to migration in high-wear applications. Its chemical profile allows integration into both water-based and solvent-based PU dispersions. This grants long-term color fastness under repeated flexing and exposure, which is mandatory for footwear, automotive, and upholstery-grade artificial leather.

Industry compliance standards

• ISO 105-X12 (color fastness to rubbing)
• GB/T 28010 (eco-labeling criteria for synthetic leather in China)
• California Proposition 65 (restricted substances in consumer goods)
