    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.

    摘要: In order to dye and print cellulose fibres swollen with water-miscible swelling agents or mixed fibres containing these fibres, the fibres are treated with dyestuffs which are free from sulphonic acid groups and carboxylic acid groups, of the general formula ##STR1## wherein R denotes hydrogen or optionally substituted alkyl, aryl or acyl,Hal denotes chlorine or bromine,n denotes a number from 0 to 2 and the ring B can optionally be further substituted or fused, with the proviso that if R denotes hydrogen or methyl, n must be >0 and/or B must be further substituted,and the dyestuffs are fixed by heat treatment.
