    摘要: The invention relates to a pigment with color dependent on the viewing angle, which has been obtained by three-dimensional crosslinking of oriented substances of liquid-crystalline structure having a chiral phase. In order to stabilize the color of such a pigment at elevated temperatures, crosslinking is carried out in the presence of at least one additional, color-neutral compound comprising at least two crosslinkable double bonds.

    摘要: A process for repairing relatively small paint faults in powder coating layers, in which, in the region of the faulty point, a cutout is introduced into the powder coating layer with precisely defined dimensions with respect to its area and also with respect to its depth. A filler made of powder coating and/or a pre-product of the powder coating is introduced into the cutout. The filler is dimensioned to correspond to the volume of the cutout, in particular corresponding to the dimensions of the cutout, and is coherent. The filler introduced is joined, in particular bonded, to the powder coating layer arranged outside the cutout.

    摘要: The invention relates to a liquid crystalline, photo cross-linkable main-chain polymer used as interferentially effective, chromophoric substance for colored paints, in which the main mesogenic groups are disposed at least approximately in a chiral-nematic manner. An etherified cellulose ether or a mixture of several etherified cellulose ethers is used pursuant to the invention as liquid crystalline main-chain polymer or polymers wherein: the cellulose ethers have a molecular weight of 500 to 1,000,000, the anhydroglucose units of the cellulose ethers are etherified with an average degree of molar substitution of 2 to 7 with propylene oxide or ethylene oxide units (C.sub.3 H.sub.6 O- or C.sub.2 H.sub.4 O-units), and the cellulose ethers are etherified with an average degree of molar substitution of 1.5 to 3 with unsaturated hydrocarbon groups (C.sub.r H.sub.2r-1).
