  • Patent number: 4682983
    Abstract: The transfer sheet is used for dry thermal printing of water swellable celluluse fibers with dyestuffs which are insoluble in water of 60.degree. C. The dyestuffs are difficult to evaporate and cannot be used in a conventional heat transfer printing process. They are transferred at 230.degree. C. and a contact pressure of 10.sup.4 -10.sup.6 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 5.times.10.sup.4 Pa.
