Dry heat process for dyeing and printing organic material

In a dry heat process for the dyeing or printing of organic textile material selected from the group consisting of polyvinyl chloride, polyamides, polyurethanes, polyesters, polymers and copolymers of acrylonitrile, and polymers and copolymers of dicyanoethylene which comprises bringing the textile material to be dyed or printed into contact with a treated transfer carrier bearing on at least a portion of at least one surface thereof at least one heat transferable organic disperse dyestuff, heating the said carrier while in contact with the said textile material at a temperature and for a time period sufficient to effect transfer of dyestuff from the carrier to the textile material, and separating the dyed or printed textile material from the carrier, the improvement wherein the transfer carrier carries at least one reactive disperse dyestuff of the formula ##STR19## wherein R.sub.1 represents hydrogen or alkyl,

• R.sub.2 represents hydrogen, alkyl, cycloalkyl, aralkyl or substituted or unsubstituted phenyl, or R.sub.1 and R.sub.2 together with the nitrogen atom to which they are attached can also form a 5- to 7-membered heterocyclic ring,
• R.sub.3 represents hydrogen or alkyl,
• R.sub.4 represents hydrogen or alkyl of 1 to 2 carbon atoms,
• X represents hydrogen, chlorine, bromine, cyano or COOR.sub.5, and
• R.sub.5 represents alkyl.
