Transfer printing process for dyeing and printing organic material which can be dyed with cationic dyes

Claim 1

In a process for the dyeing or printing of organic material by the transfer printing process which comprises bringing the surface of an inert carrier sheet treated with a printing ink into contact with the surface of an organic material which can be dyed or printed with cationic dyes, subjecting the carrier and organic material to heat treatment for a time and at a temperature sufficient to achieve dyeing or printing of the organic material and separating the organic material from the said inert carrier, the improvement according to which the printing ink for treating the inert carrier comprises a dispersion or solution of at least one member of the group of disperse dyestuffs, cationic dyestuffs, and mixtures thereof said dyestuffs being from among those which are converted to the vapour state at atmospheric pressure and at a temperature of between 150° C and 220° C and at least one organic compound as transfer promotor having a vapour pressure higher than 10 - 5 Torr at 200° C and being selected from the group of a. A compound of the formula ##STR65## b. A compound of the formula ##STR66## wherein "alkylene" is of 1 to 4 carbon atoms, R represents alkyl of 1 to 4 carbon atoms, α-hydroxyethyl, α-acetoxyethyl, cyclohexyl, phenyl, methylphenyl, dimethylphenyl, chlorophenyl, or formyl, and c. A compound of the formula ##STR67## wherein X represents oxygen or sulfur, Y represents alkylene which bonds the group ##STR68## to a ring with 5 to 7 members, and "alkylene" is of 1 to 4 carbon atoms.
