Date Sep. 14, 1995Mixtures of liquid-crystalline compounds comprising at least two different substances of the formula I +TR where Z1 and Z2, independently of one another, are polymerizable groups, Y1 and Y2, independently of one another, are each a direct bond, -O-, -COO-, -OCO- or -S-, A1 and A2, independently of one another, are spacers, and R1, R2 and R3 are conventional substituents, and novel compounds of the above formula where at least two of Z1, Z2, Y1, Y2, A1 and A2 are not identical, are described. The novel mixtures and compounds are suitable, inter alia, as base material for color-effect materials and piezomaterials, preferably in chirally doped form.
