In order to dye and print cellulose fibres, which have been swollen with water-miscible swelling agents, or fibre mixtures containing such cellulose fibres, the fibres are treated with a dyestuff of the general formula ##STR1## wherein A denotes an optionally substituted anthraquinone radical, which can contain a further fused ring,

Process for dyeing and printing cellulose fibres

In order to dye and print cellulose fibres swollen with water-miscible swelling agents or fibre blends containing these fibres, the fibres are treated with a dyestuff of the general formula ##STR1## wherein Pc denotes the radical of a Cu phthalocyanine,

For dyeing and printing cellulose fibres which have been 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 represents optionally substituted C.sub.1 -C.sub.6 -alkyl, cyclohexyl, C.sub.1 -C.sub.4 -alkoxy, phenyl, benzyl, phenylethyl, phenylpropyl or phenoxy, or chlorine or bromine,

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,

Use of the dyestuffs of the formula ##STR1## wherein R, Y and X have the meaning given in the description, for the dyeing of synthetic textiles, especially those of aromatic polyesters, by the transfer printing process. Prints obtained are distinguished by good fastness in use properties.

Branched-chain alkyl amino anthraquinones

Process for dyeing textiles

The invention relates to the transfer printing hydrophobic fibre materials using paper supports which are printed with azo dyestuffs of the formula ##STR1## wherein X.sub.1 and X.sub.2 represent hydrogen or alkyl or cycloalkyl radicals and
