Abstract
The invention discloses an ink for the engraved steel die printing process, having a viscosity at 40° C. between 3 Pa·s to 15 Pa·s, preferably 5 to 10 Pa·s, and having a polymeric organic binder and magnetic pigment particle, characterized in that said magnetic pigment particles comprises a magnetic core material which is surrounded by at least one layer of another material. The surrounding layers, single or in combination, confer the pigment particle particular optical properties in the visible and/or in the near IR, chosen from high specular or diffuse reflectance, spectrally selective absorption or reflection, and angle-dependent absorption or reflection, and allow for the formulation of inks having a large gamut of color and other optical functionalities.
