The invention provides an improvement in the known dry thermoprinting process making it possible to employ the process to dye or print natural fibers or mixtures of natural and synthetic fibers. Textile material consisting of natural fibers or of a mixture of natural and synthetic fibers is impregnated with a precondensate of a thermosetting resin. The thus impregnated material is then dyed or printed by the dry thermoprinting process, the curing of the resin taking place during the transfer of the dyestuff.

Printing process

Temporary carriers which can be used in the thermoprinting technique, and particularly in thermoprinting textiles by transfer, characterized in that they comprise a print which is generally multicolored and which is produced from an alkalizing agent and one or more cationic dyestuffs, which, at atmospheric pressure, pass into the vapor state at temperature above 160.degree. C, the said print being carried by a sheet or strip of sulphurized paper.

Sulphurized paper supports

Dry transfer printings are obtained by bringing the printed surface of a temporary carrier sheet into face-to-face contact with the surface of a substrate sheet to be printed, forming the joined sheets into a coil and heating the coil to a temperature and for a time period sufficient to cause transfer of transferable dyestuff from the printed surface of the temporary carrier to the surface of the substrate to be printed.
