Thermotransfer process for printing synthetic fibre materials with multi-color effects, and carrier for performing the process

A thermal dry transfer-printing process for printing synthetic fibre materials with multi-color effects, wherein there is used an intermediate carrier which is printed: (1) in places with at least one reserve printing paste or ink, and (2) with a printing paste or ink for printing the base (ground). The reserve paste or ink (1) contains at least: (a) one solvent, (b) one thickener, (c) optionally one non-reservable, sublimable disperse dye, (d) optionally one curing catalyst, and (e) one organic solvent and/or water. The printing paste or ink (2) for printing the base contains at least: (b) one thickener, (g) one reservable, sublimable disperse dye, (e) one organic solvent and/or water, and (f) optionally one binder. The printed intermediate carrier is fast to rubbing and is storage-stable. It is brought into contact with the fibre materials, and both are subjected to a heat treatment at elevated temperature until the non-reservable dyes are transferred from the carrier to the fibre material. There are obtained on the fibre material any desired number of patterns in the widest variety of colors and shades, the patterns having extremely sharp contours and being without aureoles.
