    Abstract: New polymerizable liquid crystalline compounds with two disubstituted phenyl groups attached to a mesogenic group via single bonds, ether, thioether, ester, amide or similar linking groups, in which the two substituents on each phenyl group are crosslinkable groups. Polymerizable liquid crystalline (LC) compounds of formula (I) are new. A , A = crosslinkable groups; X = a single bond, -O-, -S-, -C=N-, -OCO-, -COO-, -OCOO-, -CONR-, -NRCO-, -NR-, -OCONR-, -NRCOO-, -CH2O- or -NRCONR-; R = H or 1-4C alkyl; and M = a mesogenic group. Independent claims are also included for the following: (a) A method for the production of (I) by reacting a compound of formula (III) with a mesogenic compound of formula X''-M-X'' (IV). X', X'' = reactive side-groups which combine to form group X. (b) Compositions containing (I) and optionally other components selected from cholesteric (optionally crosslinkable) compounds, inorganic pigments, coloring agents and optionally polymerizable diluents or supports. (c) Pigments containing (I) in crosslinked form. (d) Coating materials containing such compositions or pigments.
