Aniline Dye

Aniline dye is a type of synthetic dye derived from aniline, a chemical compound made from coal tar. These dyes are known for their vibrant colors and excellent colorfastness, meaning they don’t easily fade. Aniline dyes are commonly used to color fabrics, leathers, and sometimes plastics. They work by bonding with materials at a molecular level, providing bright, durable hues. Because of their vividness and stability, aniline dyes revolutionized the textile industry in the 19th century and remain important in manufacturing today, although some types have been replaced by newer, less toxic alternatives.
