    摘要： The invention relates to the preparation of pulverulent formulations of transfer printing dyestuffs.The process is characterized in that the aqueous dispersions of these dyestuffs are mixed with compounds of the formulaR--ZwhereinR denotes a hydrophobic radical with at least 5 C atoms andZ denotes the groups --COOH, --NH.sub.2, --O(C.sub.2 H.sub.4 O).sub.n H, --NX.sub.1 X.sub.2 or --NH(CH.sub.2).sub.m NX.sub.1 X.sub.2,in whichn is 0, 1 or 2,m is 2-6 andX.sub.1 /X.sub.2 is H or C.sub.1 -C.sub.4 -alkyl,with the proviso that R represents a non-cyclic aliphatic radical when Z represents COOH,and the aqueous mixtures are converted into dry pulverulent form in a manner which is in itself known.The preparation can easily be dispersed in organic media, for example in organic solvents such as those customary in the preparation of printing pastes, and are outstandingly suitable for the preparation of printing inks for printing temporary supports for heat transfer printing.

    摘要： Aqueous pigment dispersions which contain organic or inorganic pigments and water-soluble oxalkylation products of compounds which are obtainable by condensation of aromatic compounds, containing phenolic OH groups, or their ethers, especially lower alkyl ethers, with formaldehyde and amines which contain at least 2 NH groups which are reactive towards formaldehyde, or derivatives of such oxalkylation products are suitable for pigmenting natural or synthetic materials.
