Abstract

The properties of crystal violet lactone (CVL), currently the most commonly used color developer in carbonless papers, were studied. The hypothesis that CVL exhibits different properties in the carbonless and in the office papers was verified, as well as the CVL´s ability to luminesce in the IR region. Furthermore, the impact of thermal and light aging on some physical and chemical properties of the copies was observed. The changes were monitored by observing the IR luminescence at several wavelength ranges. Visual, colorimetric and structure differences between the copies made on the carbonless and the office paper were analyzed. The surface structure of the carbonless paper was analyzed using SEM–EDS.
