1. It is a kind of heat sensitive and pressure sensitive dye with fast color, high chroma and good oil solubility. It is widely used in commercial invoices, computer output terminal subpoenas, information records, etc.
2. Under the acidic condition, the lactone ring is cleaved to form a quinone-type colored groupwith large π bond, which emits a bright high concentration of blue-violetand has maximum reflected light absorption at 609.8 nm.
