Acid dyes are a type of water-soluble dyes with acidic groups in the structure, which are dyed in acidic media. Most acid dyes contain sodium sulfonate, which is soluble in water, bright in color and complete chromatogram. Acid Yellow 23 is one of them;

According to chemical structure classification, acid dyes can be divided into azo, anthraquinone, triarylmethane and other categories.

1) Azo type: single and double azo dyes, mainly light colors (yellow, orange, red, purple, blue), the number of varieties accounted for the majority;

2) Anthraquinone type: monoanthraquinone is the main type, mainly dark (purple, blue, and green) varieties occupy the second place, with the best light fastness

3) Triarylmethane type: bright color, high strength, mainly purple, blue, and green, with the worst light fastness.
