    Abstract: Transfer-printing supports, which are impregnated or printed with a formulation containing a mixture of a blue disperse dyestuff which sublimes readily and has the formula in which X is hydrogen or halogen, R, R1 and R2 denote alkyl with 1 to 4 carbon atoms and R3 denotes hydrogen or alkyl with 1 to 4 carbon atoms, and yellow to red disperse dyestuffs which sublime readily, give deep and fast black dyeings on polyester materials and polyester mixed materials by the heat transfer-printing process.
