Abstract: Heat insulation covering comprises a cholesteric layer(s) that reflects at least 40, preferably at least 45% of light of IR wavelength, preferably above 750, especially 751-2000 nm. Independent claims are included for the production of the above material by applying a cholesteric IR-reflecting layer to a transparent substrate and curing, a multi-component comprising components suitable for giving cholesteric layers, and heat insulation covering sheets, preferably adhesive sheets, made of the above.

Abstract: Chiral compounds are disclosed of the formula (Z-Y-[A] m -Y-M-Y-) n X I, where, independently of one another, A is a spacer, M is a mesogenic group containing two phenylene radicals which are unsubstituted or substituted by C 1 - to C 4 -alkyl, methoxy, ethoxy, fluorine, chlorine, bromine, C 1 -to C 20 -alkoxycarbonyl or C 1 - to C 20 -alkylcarbonyl and are linked via O, CO, OCO, OCOO or COO, Y is a direct bond, O, S, COO, OCO, OCOO, CON(R) or N(R)CO, and Z is a polymerizable group, m is 0 or 1, n is from 2 to 6, and X is a chiral radical of the formula R is C 1 - to C 4 -alkyl or hydrogen, and their use as polymerizable, chiral high-twisting-power dopants for the production of cholesteric networks. These compounds are suitable for use in electro-optical displays or as chiral dopants for nematic or cholesteric liquid crystals for producing layers which reflect in color. They may also be used as chiral dopants in optical polarizers and optical filters.

Abstract: The invention relates to compounds of the general formula (I) X¢-Y1-A1-Y2-M-Y3-A2-Z!n in which X is a silicon free, n-bond central unit; the radicals A1 and A2 are, independently of one another, a direct bond or a spacer; the radicals Y1, Y2 and Y3 are, independently of one another, a direct bond, O, S, CO, OCO, COO, OCOO, (a), (b), COS or SCO; M is a mesogene group; Z is a polymerizable group; n is a number between 2 and 6 inclusive; R is hydrogen or C1-C4-alkyl; and the combination of M-Y3-A2-Z can represent a cholesterol radical. These compounds are suitable as orientation layers for liquid crystal materials, as photolinkable adhesives, as monomers for the production of chirally dopable polymerizable liquid crystal systems, as matrix monomers for polymer-dispersed displays, or as a basic material for polymerizable liquid crystal materials for optical elements, like polarizers, retardation plates or lenses.

Abstract: A process is disclosed for producing pigment particles and is characterised in that: either a polymerisable mixture containing a dye or interference colouring agent is applied to a surface with recesses in the shape of the desired pigment particles, and is then polymerised, the polymerised pigment particles being afterwards removed from the recesses; or said polymerisable mixture is applied to a smooth surface in the shape of the desired pigment particles, the shape being set in the known way by a printing process, and then polymerised, the polymerised pigment particles being subsequently removed from the surface (not including the production by offset printing of pigment particles of cholesteric-liquid crystalline structure).
