    摘要: A composition for nematic liquid crystal color display elements, said composition comprising at least one anthraquinonic dye represented by the following formula ##STR1## wherein X and Y are identical or different and represent --NH.sub.2 or --OH; Z represents halogen, --OR, --NHR, ##STR2## --CONHR.sub.2 or --COOR.sub.2, in which R represents an alkyl group having 1 to 15 carbon atoms or a lower alkyl group optionally substituted by --OH, ##STR3## R.sub.1 represents hydrogen, halogen, --OH, --OCH.sub.3, an alkyl group having 1 to 15 carbon atoms, or a methoxy group optionally substituted by ##STR4## and R.sub.2 is a phenyl group, an alkyl group having 2 to 5 carbon atoms or a cyclohexyl group; and n is an integer of 1 or 2 provided that when X is --NH.sub.2 and Y is --OH, and when X and Y are both --OH, n is an integer of 1, and when n represents an integer of 2, the two Z's may be identical or different dissolved in at least one nematic liquid crystal.

    摘要: Dyestuffs, which are free from nitro groups and sulphonic acid groups, of the formulaF--Z--(OA).sub.n --OR IwhereinF denotes an anthraquinone nucleus which contains at least one auxochromic group in the .alpha.-position,Z denotes a direct bond or a bridge member,A denotes alkylene,R denotes alkyl, aralkyl, cycloalkyl, aryl or acyl andn denotes 3 to 8,with the proviso that R does not represent aralkyl if n denotes the number 3 and the number of the auxochromic groups is two, have a melting point below 140.degree. C., in particular below 100.degree. C., and are outstandingly suitable for dyeing and printing synthetic fibre materials, in particular those of polyesters, on which they produce dyeings with good fastness to sublimation, washing and light.The dyestuffs are advantageously employed in the form of liquid or pulverulent preparations which contain, in addition to the dyestuff, emulsifying polar/non-polar compounds and, if appropriate, formulating agents and extenders.These preparations are distinguished by very high solubility in cold water and require no further dyeing auxiliaries such as, for example, carriers.
