Description

C.I.Acid Blue 226 is a synthetic acid dye belonging to the anthraquinone class, known for its bright and stable blue hue. It is valued for its excellent color fastness properties, particularly its resistance to light and washing, making it a reliable choice for demanding dyeing applications. This dye is primarily used by the textile industry for coloring protein fibers like wool and silk, as well as polyamide fibers such as nylon.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, and nylon fibers, providing vibrant blue shades with good fastness.
• Leather Coloring: Used in the dyeing of leather goods to achieve consistent and durable blue colors.
• Paper Staining: Employed for tinting specialty papers where color stability is required.
• Ink Formulation: A colorant component in the manufacture of certain inks, including those for ballpoint pens and markers.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis.
• Polymer Mass Coloration: Can be used for coloring synthetic polymers during the manufacturing process.
