Crystal violet lactone (CVL) is a common purple dye with a triarylmethane chemical structure. After undergoing a ring-opening chemical change, it forms a unique large conjugated structure, causing most of its light absorption to fall within the visible light region at around 600 nm, thus exhibiting a vibrant blue-violet color. As an important functional dye, it has the advantages of rapid color development, high chroma, and good oil solubility, and has been widely used in the production of pressure-sensitive and thermosensitive materials.
