TL;DR: In this article, a liquid-crystalline medium based on a mixture of polar compounds having negative dielectric anisotropy (Δe) was defined for active-matrix display based on the ECB, VA, PS-VA, FFS, PALC or IPS effect.

TL;DR: In this paper, the instant invention relates to liquid crystalline media comprising a dielectrically positive component, component A, consisting of dielectraically positive compounds, comprising one or more compounds of formula (I) and one or multiple compounds (II) wherein the parameters have the meaning given in the specification and liquid crystal displays comprising these media, especially to active matrix displays.

TL;DR: In this article, a multilayer pigments based on glass flakes and a method for the production of such pigments is described. But the method is not suitable for the use in laser-marking of papers and plastics.

TL;DR: In this paper, the authors proposed a multi-layer interference pigments based on multi-layered plate-like substrates with at least two sequences of layers consisting of a colourless layer with a refraction index n ≤ 1,8; a high-index layer consisting of TiO2 and Fe2O3 in a ratio of 1:0.1 to 1:5 and optionally, one or more metal oxides in quantities of ≤ 20 wt. % in relation to layer (B); and optionally an outer protective layer.

TL;DR: Pigment mixtures which have at least two components, where component A comprises effect pigments based on glass flakes and component B comprises flake-form, needle-shaped, spherical or crystalline colorants or fillers, and to the use thereof, in particular in cosmetic formulations and for the coloring or as a coating of products in the foods and pharmaceuticals sector are described as discussed by the authors.
