Description

Benzenemethanaminium, N-[4-[(2-chlorophenyl)[4-[ethyl[(3-sulfophenyl)methyl]amino]-2-methylphenyl]methylene]-3-methyl-2,5-cyclohexadien-1-ylidene]-N-ethyl-3-sulfo-, hydroxide, inner salt, aluminum salt is a complex, high-value aluminum lake pigment derived from a triarylmethane dye structure. This compound matters for its exceptional color strength, stability, and insolubility, making it a superior choice for demanding applications where color integrity is critical. It is primarily needed by manufacturers in the coatings, plastics, and specialty ink industries seeking vibrant, durable, and lightfast coloration.

Application

• Industrial Coatings and Paints: Used as a high-performance pigment for automotive, architectural, and industrial finishes requiring excellent opacity and weatherability.
• Plastics and Masterbatch Coloration: Imparts intense, stable color to a wide range of polymers, including PVC, polyolefins, and engineering plastics during compounding and molding.
• Specialty Printing Inks: A key component in high-quality inks for packaging, security printing, and decorative applications where color consistency and resistance are paramount.
• Colored Paper and Paper Coatings: Employed in the production of deeply colored papers and surface coatings for decorative and functional purposes.
• Cosmetic and Personal Care Products: Where approved, used for coloring soaps, bath products, and other non-food contact items.
• Artists' Colors and Pigments: Serves as a high-grade pigment in professional artists' paints and colorants.
