A mixed clay/calcium carbonate pigment wherein the clay pigment component has associated therewith before being mixed with the calcium carbonate pigment component a water-soluble condensed phosphate dispersing agent and a second dispersing agent which is a water-soluble salt comprising an organic macromolecular anion, for example a salt of polyacrylic or polymethacrylic acid, and wherein the calcium carbonate pigment component has associated therewith before being mixed with the clay pigment com...

A pigment of this invention comprises a ceramic scaly substrate, and metal dots or alloy dots formed on the surfaces of ceramic scaly substrate in the ratio of from 0.05 to 95% of the total surface area of ceramic scaly substrate. An inorganic compound coating film may further be formed on all over the surfaces of ceramic scaly substrate, and metal dots or alloy dots may be formed on the surfaces of inorganic compound coating film instead of on the surfaces of ceramic scaly substrate in the same...

A pigment comprises a substrate, a metallic layer formed on at least one surface of the substrate and imparting metallic luster, and a transparent inorganic compound layer formed on surfaces of the substrate and the metallic layer. Thereby, the pigment produces color by light interference of a ray reflected on a surface of the transparent inorganic compound layer and a ray passed through the transparent inorganic compound layer and reflected on a surface of the metallic layer. Thus, the pigment ...

This invention relates to a new pigment in feed for salmonides, a new feed comprising this pigment and use of this pigment. The pigment comprises a diester of astaxanthin prepared with an omega-3 fatty acid and/or a short chain carboxylic acid. By this invention a pigment for feed to salmonides that is more stable and biologically more effective than free astaxanthin and commercially available astaxanthin product, is provided.

The present invention provides a novel polymorphic form of Colour Index Pigment Yellow 12 in a crystalline form which exhibits an X-ray diffraction pattern having three prominent X-ray diffraction lines corresponding to "d" spacings of 11.82, 7.71 and 3.32.times.10.sup.-10 meters.

A double phase pigment is disclosed including a first phase of a lattice of zinc sulfide, and a second phase of a lattice of zinc oxide serving as a host for manganese oxide in solid solution. The pigment may be prepared by reacting zinc oxide and manganese sulfide in an inert atmosphere at elevated temperatures.

The present invention provides a pigment ink which can be produced through a simplified procedure and enables coloring as good as a dye ink. The pigment ink mainly consists of an intercalation compound such as a mineral of the montmorrilonite group and the hydrotalcite group, wherein at least a part of interstitial ions in the intercalation compound is substituted by dye ions having a polarity opposite to that of the interstitial ions. The pigment is dispersed in water together with a dispersion...

A pigment dispersing agent wherein a quinophthalone structure is bonded to a triazine structure through an arylene group or a heteroaromatic ring and a basic functional group is bonded to triazine ring through a connecting group which pigment dispersing agent improves an ink or a coating in fluidity and is effective for preparing a product having a low viscosity and low thixotropic properties and having excellent properties such as tinting strength, transparency and viscosity stability with the ...

The luster, compressibility and other cosmetically important properties of various pearlescent pigments are substantially improved by coating the surface of the pigment particles with a composition comprising a precipitated water-insoluble metal stearate and a surfactant.
