Abstract
Abstract Printing inks for the production of auxiliary carriers for transfer printing on acid-modified textile fiber materials, characterized in that they contain at least (a) as a dyestuff intermediate, a carbinol base of cationic dyestuffs, which can be sublimed at 160°-240° C, of the formula ##STR1## (b) a practically anhydrous neutral organic solvent and (C) A NEUTRAL RESIN WHICH IS SOLUBLE IN THIS SOLVENT.
