Abstract

In printing transfer papers with standard aqueous print pastes, the local swelling of the paper substance gives rise to the problem of the dimensional stability of the papers. These disadvantages are eliminated according to the invention by using as print pastes foamed dyestuff liquors in which the consistency of the foam acts as thickening agents. As a result the moisture content in the print pastes can be reduced.
