LUTRIF4
LUTRIF4 is a tri-fluorescent speciality product having an easy to implement fluorescent effect, for use in the printing ink and lacquer industry. In normal daylight conditions, LUTRIF4 powder is virtually invisible on paper. However, on exposure to UV-C light red fluorescence intensity becomes visible on exposure to UV-B pink fluorescence intensity and to UV-A light white fluorescence intensity becomes visible. LUTRIF4 powder is thus a highly effective special additive for coding and marking purposes (e.g. usage in security printing). Possible application fields are high quality, solvent-free or solvent-containing special printing inks.
