Abstract: Liquid-crystalline polymers having a virtually uniform molecular weight are obtainable by polymerisation of identical or different monomers of the formula I in which the variables have the following meanings: R is hydrogen, chlorine or methyl; A is a flexible, long-chain moiety which acts as a spacer; B is a mesogenic moiety built up from at least two aromatic rings linked to one another in a linear or approximately linear manner; C is an optically active, chiral moiety, in 0.01 to 0.1 molar solution in an inert organic solvent in the presence of from 1 to 40 mol %, based on the monomers, of a free-radical initiator at a temperature between 40 and 60 DEG C for from 100 to 140 hours, and subsequent isolation of the polymerisation product from the reaction mixture, and the use thereof for building up recording layers for laser-optical and electrical recording elements and for electrophotography and for the construction of liquid-crystalline display elements.

Abstract: In the process, dyes of the formula (I) … … are transferred from a carrier with the aid of a thermal printing head. In the formula, X denotes H or CN, R , R and R independently of one another denote alkyl, alkylcarbonyloxyalkyl, alkoxycarbonyloxy- alkyl, alkoxycarbonylalkyl, haloalkyl, hydroxyalkyl or cyanoalkyl or denote benzyl or phenyl which is optionally substituted by alkyl or alkoxy or denote a radical of the formula -[Y-O]m-R (II),… in which Y is C2-C6-alkylene, m is 1 to 6 and R is alkyl or phenyl, and R and R are optionally substituted alkyl or optionally substituted phenyl when X is H or R must be optionally substituted phenyl when X is H and R is H. … The dyes (I) have better solubility and/or higher lightfastness compared with the prior art and good to outstanding transfer properties.
