Description

Fluorescent Yellow Ii (Disperse) is a specialized synthetic organic dye belonging to the disperse dye class, identified by CAS No. 12223-92-6. It is valued for its bright, vivid yellow fluorescence and excellent sublimation fastness, making it a critical component for creating high-visibility, durable colorations. This product is primarily required by manufacturers in the textile and plastics industries seeking to enhance the aesthetic and functional properties of synthetic polymers.

Application

• Textile Dyeing: Primary application for dyeing hydrophobic fibers like polyester, acetate, and nylon, especially where bright, fluorescent shades are desired.
• Plastics and Polymer Coloring: Used as a colorant for engineering plastics, acrylics, and polystyrene to achieve vibrant, light-fast yellow hues.
• Ink Formulation: A key pigment for specialty inks, including those for security printing, packaging, and textile printing.
• High-Visibility Safety Products: Incorporated into materials for safety vests, warning tapes, and signage due to its strong fluorescent properties.
• Automotive Interiors: Suitable for coloring synthetic fabrics and plastic components within vehicle cabins.
• Sporting Goods: Used in the manufacturing of synthetic fabrics for sportswear and equipment where color brightness and durability are essential.
