Abstract:
The invention relates to compounds of general formula (I) in which the radicals: X is mutually independently boron; CH2 or (a), B is hydrogen, C1 to C8 alkyl, phenyl, biphenylyl or a radical of formula (II); A and A are spacers; n is 0, 1, 2 or 3; m is 1 of zero for X = CH2; M and M are possibly fluorine-, chlorine-, bromine-, cyano-, hydroxy- or nitro-substituted single or multi-nuclear aliphatic, aromatic, heteroaliphatic or heteroaromatic ring systems, the radicals Y are mutually independently a direct bond O, S, COO, OCO, OCOO, CON(R) or N(R)CO; Z and Z are polymerisable groups or hydrogen; R is hydrogen or C1 to C4 alkyl and R and R are hydrogen; possibly O, COO, OCO, OCOO or N(R)-interrupted C1 to C30 alkyl, C2 to C30 alkenyl, C1 to C30 alkanoyl or C3 to C30 alkenoyl or a radical of formula (III) where T is a direct compound, CO, CH2, CH=CH-CO, CH2CH2CO or SO2 and A, M, Y, Z, n and m have the meanings given. The compounds of the invention are suitable as e.g. chiral doping agents for electro-optical display components or for nematic or cholesteric liquid crystals for the generation of coloured reflecting coatings of the production of liquid crystalline cholesterically ordered pigments.
Abstract:
Lacquered objects of daily use are disclosed, in particular car bodies, as well as lacquers for lacquering such objects. In order to achieve new, hitherto unknown colour effects with said lacquer, at least some, and preferably only plate-like interference pigments are mixed into the lacquer. When the lacquer is applied, said interference pigments automatically orient themselves in a direction approximately parallel to the object surface. These interference pigments are made of liquid crystal side chain polymers (LCP) with a nematic and a chiral component, in which the side group mesogenes are at least approximately nematic, smectic and/or cholesteric. Particularly intensive tones having a hitherto unknown brilliance may thus be obtained on the lacquered object, or a shimmering effect depending on the angle of incidence of light and viewing direction.

Abstract:
The present invention generally provides a method for increasing the dispersibility of a cationic molecule of interest through the ion exchange of the cationic molecule onto the surface of a substrate having a high surface area. The present invention further provides for the resulting compositions whereby a cationic molecule of interest has been incorporated onto the surface of a high s urface area substrate and where the resulting cation/substrate (such as a cation/organoclay) composition experiences greater dispersibility in a target application system than the cationic molecule of interest alone experiences in that same application system. The method of the present invention further serves to substantially reduce the water solubility of the cationic molecule of interest by incorporating it into a high surface area substrate such as an organoclay. Also, the method of the present invention serves to improve the efficacy of the cationic molecule of interest.
Abstract:
Die Erfindung betrifft Formkörper mit optischem Effekt, im wesentlichen bestehend aus Kern-Mantel-Partikeln, deren Mantel eine Matrix bildet und deren Kern im wesentlichen fest ist und eine im wesentlichen monodisperse Grössenverteilung aufweist, wobei ein Unterschied zwischen den Brechungssindices des Kernmaterials und des Mantelmaterials besteht, dadurch gekennzeichnet, dass in die Matrix mindestens ein Kontrastmaterial eingelagert ist.
Abstract:
The invention describes luminescent optically variable pigments (OVP), methods for obtaining such pigments, as well as the use of such pigments as security elements in inks, coatings and articles. The luminescence centers are preferably incorporated into the dielectric material of the OVP's optical Fabry-Perot resonance cavity, allowing for the machine-discrimination of luminescent OVP from simple mixtures of luminescents and non-luminescent OVP.
Abstract:
A process for producing an effect coating with a colour impression depending on the viewing angle in which one or more no-setting cholesteric liquid crystalline polymer(s) or at least one non-setting nematic and at least one non-setting cholesteric liquid crystalline polymer is/are applied in the form of a melt of in solution to the object to be coated and converted by heat treatment into a film with a colour effect depending on the viewing angle.
