The invention relates to a non-dusting homogeneous pigment preparation notable in that it comprises at least 40% by weight of one or more effect pigments, from 0.5 to 50% by weight of water and/or an organic solvent or solvent mixture and from 0.5 to 59.5% by weight of a styrene-modified polyacrylate resin having an acid number &#x3e;90 mg KOH/g, and to its use to produce dry preparations.

Pigment preparation

The present invention relates to a pigment preparation comprising a mixture of coated and/or uncoated SiO flakes, one or more special-effect pigments, and a phosphate derivative, and to the use thereof, especially in printing inks.

Pigment preparation and its use especially in printing inks

The invention relates to a non-dusting homogeneous pigment preparation which is notable in that it comprises at least 40% by weight of one or more effect pigments, from 0.5 to 60% by weight of an aldehyde resin and/or ketonic resin and from 0.1 to 10% by weight of a redispersant.

Organosilicon compounds

The invention relates to a non-dusting homogeneous pigment preparation notable in that it comprises at least 40% by weight of one or more pearl lustre pigments.

Pigment composition

The present description relates to a roller wash composition for the cleaning of the cylinder, polymer plate and other soiled parts of printing machines when using water-based printing inks.

Roller wash composition

The present invention relates to surface-modified pigments based on platelet-shaped substrates, having improved settling and reagitation characteristics, and to their preparation processes and use.

Surface-modified platelet-shaped substrates

The present invention relates to surface-modified pigments based on flaky substrates having improved settling and redispersing characteristics and to the preparation and use thereof.

Surface-modified flaky substrates having improved settling and

The present invention relates to surface-modified pigments based on platelet-like substrates which, for improving the settling and redispersion behavior, have been recoated with a mixture comprising two metal oxides selected from the group consisting of silica, alumina and zirconium dioxide.

Surface-modified pigments

The present invention relates to a low-viscosity offset printing ink which essentially comprises a binder, additives and 5-40% by weight of pearlescent pigments and has an improved transfer behavior for pearlescent pigments.
