Abstract: The present invention relates to easily distributable pigment compositions consisting essentially of pigment and urea-aldehyde resin, wherein the weight ratio of pigment to urea-aldehyde resin is generally in the range of 40:60 to 90:10, a process for their production and their use in pigmenting high molecular weight organic materials. Due to the excellent dispersibility of the pigment compositions of this invention, uniform distribution of pigment particles throughout the entire application media and, therefore, excellent color consistency is readily achieved. Products, for example solvent paints, spread coatings and powder coatings, comprising the stir-in pigment compositions show high color strength, high gloss and low haze as well as very good light fastness and weathering fastness.

Abstract: Pigment powder mixtures, consisting of0.999-0.5 part of C.I. Pigment Yellow 184, and0.001-0.5 part of an organic pigment selected from the group consisting of C.I. Pigment Orange 13, C.I. Pigment Orange 34, C.I. Pigment Orange 36, C.I. Pigment Orange 73, C.I. Pigment Red 170, C.I. Pigment Red 254, C.I. Pigment Red 255 and C.I. Pigment Red 264,or of0.99-0.5 part of C.I. Pigment Yellow 184, and0.01-0.5 part of an organic pigment selected from the group consisting of C.I. Pigment Yellow 83, C.I. Pigment Yellow 110 and C.I. Pigment Yellow 139.These pigment powder mixtures are distinguished, in particular in paints, by very high chroma.

Abstract: Transparent bismuth vanadate pigments and a process for their preparation. Coating bismuth vanadate pigment precursors prepared by known methods with coating compositions conventionally used for coating pigments prior to the customary calcination gives bismuth vanadate pigments of high transparency.

Abstract: The production of iron blue pigment compositions by a flushing process has been found to be improved by carrying out the flushing step in the presence of an amine flushing agent and incorporating into the composition during or after flushing at least one surfactant of the polyoxyethylene type. The resulting iron blue compositions have improved consistency and dispersibility in printing inks, paints and the like.

Abstract: Metal phthalocyanines having a narrow particle size distribution are synthesized via the phthalodinitrile or phthalic anhydride-urea route using hexachlorobutadiene as the diluent. Higher yields and shorter reaction times are also realized by carrying out the syntheses in this manner.
