The invention relates to a nondusting, solvent-containing homogeneous pigment preparation that includes ≧70% by weight of one or more effect pigments 0.1-30% by weight of an organic solvent or solvent mixture having an evaporation number (EN) of 10 to 100 and a surface tension (ST) of ≦35 mN/m and optionally 0-5% by weight of a surface-active substance.
摘要:
The present invention relates to a pigment preparation comprising BiOCl pigments, one or more luster pigments and spherical particles, and to the use thereof in printing inks, security printing inks, surface coatings, paints, plastics and in cosmetic formulations.
摘要:
The invention relates to a coated system which has a chemically and mechanically very stable surface coating of high aesthetic attraction which has a specular and optionally iridescent color and/or a body color on a metal, ceramic or quartz glass substrate provided with an enamel or glaze coating, the surface coating being obtainableby single or repeated application of aqueous metal oxide sols,by subsequently drying and optionally igniting the metal oxide sol coating at each application step,the metal oxide sols having a mean particle size of between 5 and 200 nm,ignition being carried out at least once after completion of the final application step and at temperatures higher than 700.degree. C. and below the softening point of the substrate,the metal oxide coating on the glaze or enamel coating having, after ignition, a refractive index at least 0.5 higher than the refractive index of the enamel or glaze coating, andthe total thickness of the ignited metal oxide coatings being less than 500 nm.
摘要:
Colored pigments having an improved stability in decorative colors, engobes, glazes, and enamels, based on platelet-type substrates coated with metal oxides, in which the coating is free from alkaline earth metal oxides and contains a colored metal oxide or metal hydroxide and at least 10% by weight of aluminum oxide, are outstandingly suitable for pigmenting glazes and enamels.
