Crystal violet lactone CAS# 1552-42-7

Crystal violet lactone is a fast-developing, high-chromaticity, heat-sensitive and pressure-sensitive dye. It is widely used in commercial invoices, computer-generated terminal subpoenas, intelligence records, and other fields. Its fast color development performance and high chromaticity ensure that the handwriting on printed or recorded materials is clear and distinct, easy to read and identify. In these applications, crystal violet lactone can quickly change color according to changes in temperature or pressure, providing an effective anti-counterfeiting and identification method for related documents and records.
