Abstract
The invention relates to transfer-printing carriers for printing sheet-like articles made from polyacrylonitrile, which carriers carry, as the red component, a mixture of dyes of the two types ##STR1## wherein A is an ether group, n is an integer having a value of at most 4, X is a hydrogen atom or a low-molecular alkyl group optionally containing substituents, and Y is a low-molecular alkyl group optionally containing one substituent. The ratio of the dyes of the types I and II present in the mixture has to be 1:3 to 3:1.

In a transfer-printing carrier which carries a design which is volatile at 180.degree. to 210.degree. C., the improvement wherein the design is one which contains as the red component a mixture of dyes of the two types ##STR5## wherein A is methoxy, phenoxy or hydroxyethoxy, n is an integer having a value of at most 4, X is a hydrogen atom or lower alkyl, and Y is lower alkyl, the dyes of the types I and II present in the mixture being in the ratio to one another of 1:3 to 3:1.
