2.Crystal violet lactone(CVL )Functions:
CVL is a good thermal and pressure-sensitive dye that has the following advantages: discoloration fast andhigh chromaticity and oi-soluble, widely used in commercial invoices, computer output terminasummons,information records, etc.

3.Crystal violet lactone(CVL )Workshop.
General dye is a colored conjugated system in addition to the CVL. CVL can be used as a thermal andpressure sensitive dye, its conjugated system is interrupted. So CVL has no color. But it will be colored withthe effect of chromogenic agent. Under acid conditions, CVL will show violet color(bright, highconcentrations).
cVL is an important functional dye in the production of pressure-sensitive materials or heat-sensitivematerials.

Aspect of usage:
CVL can be used in most grades of heat-sensitive paper(thermal paper), to produce intense black image with excellent image stability, to exhibits high thermal sensitivity.
