    • 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.
    • 本发明涉及转印印花染料的粉末制剂的制备。 该方法的特征在于将这些染料的水分散体与式RZ化合物混合,其中R表示具有至少5个C原子的疏水基团,Z表示基团-COOH,-NH 2,-O(C 2 H 4 O)n H, -NX1X2或-NH(CH2)mNX1X2,其中n为0,1或2,m为2-6,X1 / X2为H或C1-C4-烷基,条件是R表示非环状脂族基团 当Z表示COOH时,并且水性混合物以本身已知的方式转化为干粉状。 该制剂可以容易地分散在有机介质中,例如在诸如印刷浆料制备中常用的有机溶剂中,并且非常适用于制备用于印刷传热印刷的临时载体的印刷油墨。
