The transfer sheet is used for dry thermal printing of water swellable celluluse fibers with dyestuffs which are insoluble in water of 60 DEG C. The dyestuffs are difficult to evaporate and cannot be used in a conventional heat transfer printing process. They are transferred at 230 DEG C. and a contact pressure of 104-106 Pa from a base paper provided with a release coating, to cellulose fibers which have been swollen with water and the swollen state of which has been preserved after drying with a polyglycol. I order to increase the penetration of dyestuffs into the textile structure, it is recommended to lower the air pressure in the transfer area down to a pressure ranging from 1 to 5x104 Pa.
