Flüssig-kristallines, UV-beständiges Silicon; Pigmentgrundmischung, Beipielssubstanz 7 In völlig gleicher Weise, wie in Beispiel 6 beschrieben, wurde aus 4-Allyloxybenzoesäurecholesterinester, 1,3,5,7-Tetramethylcyclotetrasiloxan und 4-Allyloxybenzoesäure-[4-(6-methacryloylhexyl)cyclohexyl]-ester = Beipielssubstanz 5 ein Oligomer hergestellt und in ebenfalls gleicher Weise, wie in Beipiel 6 beschrieben, mit der äquimolaren Menge an 4-Allyloxybenzoesäure-[4-(6-methacryloylhexyl)cyclohexyl]-ester abgemischt und die Lösung mittels eines Dünnschichtverdampfers bei 25 mbar Druck und einer Heizmanteltemperatur von 90°C vom Lösungsmittel befreit (Restgehalt < 1 Gew.% Toluol). Der so erhaltene Flüssigkristall besitzt einen Glasübergang bei ca. -11°C. Die Klärtemperatur (Peak) von cholesterisch zu isotrop liegt bei 67 °C. Die Viskosität beträgt bei 90°C ca. 1190 mPas. Bei 40 °C orientierte und UV-vernetzte dünne Filme des Materials weisen nach dem Abkühlen auf Raumtemperatur eine Reflexionswellenlänge von 555 nm auf.

Example 7 Liquid-crystalline, UV-stable silicone; pigment base mixture, Substance Example 7 In entirely the same manner as described in Example 6, an oligomer was prepared from cholesteryl 4-allyloxybenzoate, 1,3,5,7-tetramethylcyclotetrasiloxane and 4-(6-methacryloylhexyl)cyclohexyl 4-allyloxybenzoate=(Substance Example 5) and, likewise in the same manner as described in Example 6, mixed with an equimolar amount of 4-(6-methacryloylhexyl)cyclohexyl 4-allyloxybenzoate, and the solution freed from solvent by means of a thin-film evaporator at a pressure of 25 mbar and a heating-jacket temperature of 90° C. (residual content<1% by weight of toluene). The resultant liquid crystal has a glass transition at about −11° C. The clearing point (peak) from cholesteric to isotropic is at 67° C. The viscosity is about 1190 mPas at 90° C. UV-crosslinked thin films of the material which have been aligned at 40° C. have, after cooling to room temperature, a reflection wavelength of 555 nm.
