Abstract
In a process for printing on leather substrates using the transfer printing method by surface treatment of the substrate, applying an auxiliary carrier which is printed on with sublimable dyes and transferring the dyes to the substrate by dry heat treatment, the surface of the substrate is impregnated with an aqueous solution of a pre-condensate of a urea aldehyde resin or melamine aldehyde resin, the solvent is removed at a temperature which still does not cause condensation of the pre-condensate, and the dyes are transferred at a temperature of between 140.degree. and 250.degree. C. for a sufficiently long time for the pre-condensate to condense out at the same time.
