ABSTRACT:
Transfer printing process for dyeing or optical brightening of hydrophilic fibre material, synthetic fibre material, or mixtures of hyrophilic and synthetic fibre material with transferable dyestuffs or optical brighteners, characterized in that for dyeing or optical brightening inert temporary carriers are used which are treated with at least one transferable dyestuff or optical brightner, at least one solid compound which melts during the heat exposure of the transfer process and has a vapor pressure above 10.sup.-5 mm Hg at 150.degree. to 250.degree. C and, optionally, a binder which is stable below 230.degree. C.
