Security Absorbers


We supply a variety of dyes that absorb and fluoresce in NIR spectrum and can be used as security inks. Our dyes have fluorescent or absorption profiles that can be specifically tuned to create key identifying signatures. We have the ability to modify dye ligands to increase solubility for ink and thin film coating applications. Our dyes can achieve high optical density even at thicknesses as thin as 5 microns. We pride ourselves on our quality and dye purity. All of the dyes in our catalog are stable for standard thermoplastic extrusion and injection molding.
