Description

Tetrasodium [[[[5-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-2-Sulphophenyl]Amino]Sulphonyl]-29H,31H-Phthalocyaninetrisulphonato(6-)-N29,N30,N31,N32]Cuprate(4-) is a high-performance, water-soluble copper phthalocyanine derivative with a reactive triazine group. This compound is valued for its intense color and ability to form covalent bonds with substrates, offering superior fastness properties. It is primarily utilized in the textile industry for dyeing and printing cellulosic fibers, as well as in the production of specialty inks and colorants where high stability is required.

Application

• Reactive Dye for Cellulosic Fibers: Primary application for dyeing and printing cotton, viscose, and other cellulosic materials, providing excellent wash and light fastness.
• Specialty Ink Formulation: Used in the manufacture of high-quality inks for packaging, security printing, and digital textile printing.
• Functional Colorant: Employed in applications requiring a stable, intense blue-green colorant that can be chemically anchored to a surface.
• Research & Development: Serves as a key intermediate or reference standard in the development of new reactive dyes and colorant technologies.
• Paper Coloring: Potential use in specialty paper production where color fastness is critical.
