Cartax DP liquid

Fluorescent Pigment Dispersion for Special Marking Applications

Cartax DP liquid is a water based pigment dispersion with pronounced fluorescent effect. In normal daylight conditions Cartax DP liquid is virtually invisible on paper. However, on exposure to UV-A light (optimal effect achieved at approx. 366 nm) the very distinct yellow-green fluorescence becomes visible (emission at approx. 533 nm). Due to the fluorescent effect and invisibility at daylight this product is mainly used for marking, coding or security application. Cartax DP liquid can be used for water based applications. It can either be added to security paper or be used for a water based printing process.
