    Abstract: New liquid crystalline mixtures comprise: (a) difunctional mesogenic compound(s) (I); (b) reactive compound(s);and (c) optionally additives. New liquid crystalline mixtures comprise: (a) at least one difunctional mesogenic compound of formula Z1-Y1-A1-Y3-M-Y4-A2-Y2-Z2 (I); (b) at least one reactive compound selected from (i) vinyl or allyl ethers, (ii) vinyl or allyl esters of (un)saturated carboxylic acids, (iii) (meth)acrylate esters of mono- or polyfunctional alcohols, (iv) polyester (meth)acrylates, (v) vinyl (hetero)aromatic compounds, and (vi) N-vinyl amide or amine compounds of formula CH2=CH-NR1R2 (II); and (c) optionally further additives. Z1, Z2 = reactive groups (preferably photopolymerizable groups); Y1 - Y4 = direct bond, O, S, OC(O), OC(O)O, C(O)NR, NRC(O), OC(O)NR, NRC(O)O or NRC(O)NR; R = H or 1-4C alkyl; A1, A2 = 1-30C spacers, in which the carbon chains are optionally substituted by one or more Me, F, Cl or Br and interrupted by one or more O, S or non-adjacent NH or N(1-4C alkyl); M = mesogenic group; R1, R2 = -C(O)R3 or R3; R2, R3 = H or 1-4C alkyl; R2 + R3 = optionally unsaturated 3-5C alkylene (in which 1 or 2 CH2 groups are optionally replaced by NH, N(1-4C alkyl), N(6-10C aryl) or O and 1 or 2 CH group are optionally replaced by N).

    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.
