ANTHRAQUINONE DYE
Document Type and Number:
Japanese Patent JPS54120637
Kind Code:
A
Abstract:
Dyestuffs, which are free from nitro groups and sulphonic acid groups, of the formula F-Z-(OA)n-OR I wherein F 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 and n 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 DEG C., in particular below 100 DEG 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.
