Process for dyeing sheet-like structures Abstract The invention relates to a process for dyeing cellulose fibres, polyamide fibres or glass fibres containing texiles with disperse dyestuffs according to the principle of heat transfer printing method. In this process the textile is impregnated with an aqueous liquor containing a) a water-miscible organic solvent for disperse dyestuffs which boils above 140°C, b) a crosslinking agent and c) a high polymer which can be dyed with disperse dyestuffs dried and is brought into close contact with a printed temporary support and is subject to a heat treatment at 160 to 250°C. In this way prints with high colour depth on said textile materials are obtained without having any waste-water problems. Le A 16 865
