  • Patent number: 10745575
    Abstract: The invention relates to an offset printing ink containing platelet-shaped aluminum pigments with an average thickness h50 ranging 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.

  • Patent number: 10743420
    Abstract: Methods and composition sets for forming etch-resist masks on a metallic surface are provided. The method may include applying a composition comprising a first reactive component onto a metallic surface to form a primer layer; and image-wise printing by a nonimpact printing process on the primer layer another composition comprising a second reactive component to produce an etch-resist mask, wherein when droplets of the second composition contact the primer layer, the reactive components undergo a chemical reaction so as to immobilize the droplets. The set may include a first liquid composition comprising a fixating reactive component and a second liquid composition comprising an etch-resist reactive component, wherein the fixating reactive component and the fixating reactive component are capable undergoing a chemical reaction to form a bi-component material that is insoluble in water and in an acidic etch solution.

  • Patent number: 10723902
    Abstract: A method of forming transparent electrodes using printable conductive ink containing conductive materials dispersed in a viscous liquid which upon printing and thermal treatment will vaporise fully leaving behind the conductive material only. The viscous liquid acts as a medium by which conductive material dispersions are made processable for use in various printing techniques, allowing conductive patterns to be printed onto substrates (e.g. plastics, glass, metals, ceramics).
