Description

Copper, [29H,31H-Phthalocyaninato(2-)-N29,N30,N31,N32]-, Aminosulfonyl Sulfo Derivs., Sodium Salts is a water-soluble, sulfonated copper phthalocyanine derivative, representing a high-performance functional dye and pigment intermediate. This compound matters for its exceptional color strength, stability, and versatile reactivity, making it a critical precursor for advanced colorants. It is primarily needed by manufacturers in the textile, ink, and specialty coatings industries seeking to produce brilliant, durable blues and greens with enhanced solubility and application properties.

Application

• Textile Dyeing & Printing: As a key intermediate for producing reactive and direct dyes for cotton, silk, and nylon, offering excellent wash and light fastness.
• Inkjet Inks: Used in the formulation of high-quality cyan inks for home and industrial printers, providing vibrant color and stability.
• Industrial Coatings: Serves as a colorant precursor for paints, lacquers, and plastics where high color value and dispersion are required.
• Paper Coloring: Employed in the production of colored papers and paper coatings.
• Functional Dyes: Potential use in electronic applications, sensors, or as a photosensitizer due to its phthalocyanine core structure.
• Biological Staining: May be utilized in histological stains or as a contrast agent in certain analytical techniques.
