摘要:
Multilayer interference pigments consisting of a transparent carrier material coated with alternating layers of metal oxides of low and high refractive index, the layers of the metal oxides of low refractive index being optically inactive.The thickness of the metal oxide layers of high refractive index is an integral multiple of the optical thickness which is necessary for the desired interference color.The layer thickness of metal oxide layers of low refractive index is from 1 to 20 nm.
摘要:
Platelet-shaped colored pigments containing titanium dioxide, one or more suboxides of titanium and an oxide or oxides of one or more metals other than titanium or non-metals and a process for the preparation thereof is disclosed.
摘要:
In mica/titanium dioxide pigments reliable rutilization is obtained with small amounts of tin by precipitating tin dioxide directly on the mica and completing this precipitation before the precipitation of titanium dioxide is started.
摘要:
Base lacquers suitable for use in multi-layer lacquerings containing a layer of base lacquer and a layer of clear lacquer on top of this, contain a nacreous pigment based on mica flakes coated with metal oxides, wherein the nacreous pigments have a particle size substantially in the range between 5 and 25 .mu.m. The resultant lacquerings have advantageous properties.
摘要:
The present invention relates to effect pigments based on thin glass flakes and to a method for the production of such pigments. The resulting pigment can be used in any application for which pearlescent pigments have been heretofore used-such as, for example, in plastics, paints, inks, cosmetic formulations, coatings including solvent or waterborne automotive paint systems, powder coatings, inks and agriculture foils.
摘要:
The present invention relates to interference pigments based on coated flake-form substrates which are distinguished by the fact in that they comprise (A) a layer of SiO2 having a layer thickness of 5-350 nm, (B) a high-refractive-index coating having a refractive index n of >1.8 and/or (C) an interference system consisting of alternating high- and low-refractive-index layers and optionally (D) an outer protective layer, and to the use thereof in paints, coatings, automotive paints, powder coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, paper, in toners for electrophotographic printing processes, in seed, in greenhouse sheeting and tent awnings, as absorbers in the laser marking of paper and plastics, in cosmetic formulations, for the preparation of pigment pastes with water, organic and/or aqueous solvents, and for the preparation of pigment preparations and dry preparations.
摘要:
The present invention relates to color pigments based on substrates which are coated with a doped layer of iron(III) oxide, to processes for their preparation and to their use, especially in aqueous coating systems.
