General description

Crystal Violet lactone (CVL) is a colorless lactone derivative of crystal violet. The CVL compound contains two dimethylaniline groups attached via a tetrahedral carbon atom to 6-dimethylaminophthalide at the third position.

Application

Crystal violet lactone is suitable for use in color-changing printing. It serves as a reversible color system with temperature change.
