Abstract:
The use of an effect pigment (a) comprising an aluminum-based substrate and an iron oxide coating having a red 1st order interference color in combination with a colored absorption pigment (b) for producing a coating having enhanced coloristic properties, in particular enhanced chroma, lightness and hiding power, is provided. The pigment combination of (a) and (b) is suitable for coloring plastics, a fiber, a film and a coating composition such as a paint, a printing ink, a varnish or a powder coating, preferably an automotive, an architectural or an industrial coating composition.
Abstract:
The present invention relates to pigment compositions with improved and adjustable sparkling effect comprising A) a platelet-like perlite; and B) an effect pigment; and a process for their production and their use in paints, ink-jet printing, for dyeing textiles, for pigmenting coatings (paints), printing inks, plastics, cosmetics, glazes for ceramics and glass. The pigment compositions show an improved sparkle effect; in particular an attractive high sparkle intensity.

Abstract:
The present invention relates to a process for preparing a colored effect pigment, comprising: (i) coating aluminum-based substrate particles in an aqueous coating medium with at least one metal oxide layer, wherein the metal oxide is selected from a titanium oxide, an iron oxide, or any mixture thereof, (ii) providing a mixture of the coated aluminum-based substrate particles and a particulate inorganic non-metallic material in the aqueous coating medium by adding the particulate inorganic non-metallic material to the aqueous coating medium, and (iii) separating the mixture of the coated aluminum-based substrate particles and the particulate inorganic non-metallic material from the aqueous coating medium and subjecting the separated mixture to a thermal drying step so as to obtain a dry colored effect pigment material.
Abstract:
The present invention provides a process for imparting a simulated patina, or antique appearance to a substrate by using a coating composition comprising a perlite based effect pigment. The perlite based effect pigment functions as colorant and matting agent and shows an almost angle independent brightness. The process provides, for example, decorative wall coatings showing enhanced antique, or patina effects as compared to conventional effect pigments on basis of mica.
Abstract:
Described are thin plane-parallel aluminum flakes illustrated in Fig. 1 having a thickness of up to 200 nm and comprising an inner layer of oxidized aluminium having a thickness of 0.5 - 30 nm, a process for the manufacture thereof and the use thereof, e.g. in formulations, like paints, electrostatic coatings, printing inks, plastics materials, and cosmetics. Surprisingly, due to the inner layer of oxidized aluminum the aluminum flakes have an improved shear stability as evidenced e.g. by the difference in lightness before and after shear stress.
Abstract:
The present invention relates to pigments with improved and adjustable sparkling effect comprising A) a plate-like substrate of perlite coated with (a) dielectric material, and/or metal; and B) a plate-like substrate of mica, coated with (a) dielectric material, and/or a metal; and a process for their production and their use in paints, ink jet printing, for dyeing textiles, for pigmenting coatings (paints), printing inks, plastics, cosmetics, glazes for ceramics and glass. The pigments show an improved sparkle effect; in particular an attractive high sparkle intensity.
