Abstract: The invention relates to a method of printing onto the surface of a substrate, which method comprises a. coating a donor surface with a monolayer of individual particles, b. treating the surface of the substrate to render the affinity of the particles to at least selected regions of the surface of the substrate greater than the affinity of the particles to the donor surface, and c. contacting the surface of the substrate with the donor surface to cause particles to transfer from the donor surface only to the treated selected regions of the surface of the substrate, thereby exposing regions of the donor surface from which particles are transferred to the corresponding regions on the substrate, and characterised in that at least 50 wt.

Abstract: A metallic effect pigment with an additive, the additive being applied on at least a portion of the metallic effect pigment. The additive comprises, as structural units, at least one carboxylic acid having at least 4 carbon atoms and also at least one polyglycol ether. The carboxylic acid and the polyglycol ether are bonded covalently to one another. The disclosure is also directed to a method for producing these metallic effect pigments, and to the use thereof, as well as to a printing ink comprising the pigments.

Abstract: The present disclosure is directed to a pigment preparation comprising aluminum effect pigments, a solvent and at least one additive, wherein the aluminium effect pigments have a d98 value of the volume averaged particle size distribution curve of less than 15 ?m, the at least one additive is a phosphorous containing additive, and the solvent has a viscosity equal to or more than 1.8 mPa's at 25° C. The disclosure is further directed to an ink jet printing ink as well the use thereof.

Abstract: Platelet-shaped, copper-containing, metallic effect pigments which have a copper content of 60% to 100% by weight, based on the total metal content, the metal pigments having a thickness distribution as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative undersize distribution, a) with an h50 of 10 to 50 nm, and b) with an h90 of 20 to 70 nm, the platelet-shaped, copper-containing, metallic effect pigments being produced by milling a copper-containing metal powder with lubricant. The disclosure further relates to a process for producing these pigments, and also to their use, to a printing ink comprising the pigments of the invention, and to a coated article comprising these pigments.

Abstract: A mixture of platelet-shaped, copper-containing metallic effect pigments having a copper content of 60% to 100% by weight, based on the total metal content, with at least one further component, where the copper-containing metallic effect pigments have a thickness distribution, determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative undersize distribution, a) with an h50 of 10 to 100 nm, and b) with an h90 of 20 to 150 nm, and in that the at least one further component is a cellulose derivative selected from the group consisting of alkylcellulose, hydroxyalkylcellulose, alkyl(hydroxyalkyl)cellulose, and mixtures thereof, and/or is at least one additive having antioxidative and/or radical-inhibiting properties. The disclosure further relates to a method for producing this mixture, and to a coating composition.
