Description
A large class of dyes containing one or more acidic end groups (sulfonic, phenolic, carboxylic, etc.) that react with the basic end groups found in amides (silk, wool, leather, and nylon) to form a uniform, lightfast color. Acid dyes are rarely used on cotton or linen. These dyes are soluble in weak solutions of acetic, formic, or sulfuric acid and are normally applied from a fairly neutral dye bath of pH 6 or 7.
Synonyms and Related Terms
anionic dye; colorante ácido (Esp.); colorant acide (Fr.); colorante acido (It.); corante ácido (Port.)
Other Properties
Soluble in weak acid solutions.
