UV fluorescent security materials are able to absorb non-visible light in the UV‑A (365 nm, black light), UV‑B (300 nm), or UV‑C (254 nm) region and emit visible light in the whole range of the visible spectra. LuminoChem’s special luminescent products have an easy to implement fluorescent effect displaying colours from ice blue to deep red.
Security texts, marks and drawings that are not visible under normal light are made with Luminescent pigments. While they can be easily verified using a very simple Ultra Violet light or a special luminescence sensor.

Luminescent pigments and fluorescent dyes are used for invisible security features which get printed on the product surface, packaging and labels. Such hidden “marks” can be sensored only with UV light or special taggant detector.
LuminoChem offers a wide range of colours. As well as the widely used reds, yellows, greens and blues, we have developed shades of white, pink, purple and orange which are increasingly being used in the security industry. In addition, LuminoChem is able to offer a library of newly developed colours which are available for testing.
Luminochem has more than 150 unique luminescent materials. Our pigments are available in d90 < 2 µm particle size distribution, however the premium quality is d90 < 1 µm. The light fastness is measured according to the blue wool scale (1-8) and the chemical stability is measured in oxidative offset ink on a 5-1 (5 is the best) scale.
