  • Applications

    Basic Blue 7 is used primarily as a cationic dye in textile dyeing, notably for protein fibers such as wool and silk and for certain synthetic fibers; it also serves as a colorant for paper and for inks, coatings, and packaging substrates. It is commonly employed as a dye intermediate in pigment manufacture and as a colorant for plastics and polymers, helping impart blue hues to molded parts and films. Additionally, it is used in leather dyeing and finishing.
