Abstract
The invention relates to an offset printing ink containing platelet-shaped aluminum pigments with an average thickness hranging from 15 to 80 nm, binders, and solvents. The invention is characterized in that the platelet-shaped aluminum pigments are produced using a PVD method and are at least partly coated with a leafing additive, and the offset printing ink has a viscosity of 4 to 15 Pa s, measured on a sample which is temperature-controlled at 25° C. by means of a rotation viscometer with a cone/plate geometry under a shear stress of 185.9 Pa. The invention further relates to a method for producing a high-gloss printed metal image on a substrate, having the following steps: a) optionally applying a primer onto the substrate; b) applying an offset printing ink according to the invention onto the primer layer or onto the substrate, thereby forming a high-gloss printed layer B, and c) optionally applying additional color layers C onto the layer B.
