Description

Acid Mordant Orange 14 is a synthetic organic dye belonging to the azo dye class, specifically formulated for use as a mordant dye. This compound is valued for its ability to form stable, colorfast complexes with metal ions, resulting in vibrant and durable orange hues on various substrates. It is primarily utilized by manufacturers in the textile, leather, and specialty chemical industries for dyeing protein-based fibers like wool and silk, as well as for staining applications.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, and nylon fibers to achieve orange shades with excellent wash and light fastness when used with appropriate metal mordants like chromium or aluminum.
• Leather Coloring: Used in the tanning and finishing industry to impart consistent and durable orange colors to leather goods.
• Biological Staining: Employed in histology and microscopy as a selective stain for tissue samples in laboratory settings.
• Paper and Pulp Coloring: Suitable for tinting specialty papers where color stability is required.
• Ink Formulation: A component in the manufacture of certain industrial inks and pigments.
• Research & Development: Serves as a chemical intermediate or reference standard in synthetic chemistry and dye research laboratories.
