Dyes

Dyes are colored materials because they absorb only some certain wavelengths of visible light and have an affinity to the substrate they are used on. Dyes are commonly used in aqueous solutions and may require mordant to increase the fastness of the dyes to the fibers. Dyes are generally soluble in water, and some dyes can be made insoluble by adding salts to produce lake pigments. Dyes are classified according to their solubility and chemical properties. Alfa Chemistry is committed to providing a wide range of dyes. There are also many other dyes such as cationic dyes, direct dyes, neutral dyes, solvent dyes, coupler and pigments at Alfa Chemistry.
