This type of dye is mainly used to dye non-aqueous media, such as oils, paints, plastics, cosmetics, inks, etc. The main difference between solvent dyes and water-based dyes is their dissolution medium: solvent dyes rely on organic solvents, while water-based dyes rely on water.

[0003] Lipophilic solvent dyes are a type of solvent dyes. Most existing lipophilic solvent dyes have poor durability, resulting in poor color fastness and poor adhesion, which affects product quality.
