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.

Metal effect pigment with additive

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 dvalue of the volume averaged particle size distribution curve of less than 15 &#x3bc;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&#xb0; C. The disclosure is further directed to an ink jet printing ink as well the use thereof.

Pigment preparation and ink jet printing ink

The present disclosure is directed to a pigment preparation comprising aluminum effect pigments, a solvent and at least one additive, wherein the aluminum effect pigments have a dvalue of the volume averaged particle size distribution curve of less than 15 &#x3bc;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&#xb0; C. The disclosure is further directed to an ink jet printing ink as well the use thereof.

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,

Platelet-shaped, copper-containing, metallic effect pigments, process for preparing them and use thereof

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,
