摘要:
The invention relates to a process for the manufacture of prints which are fast to wet processings and sublimation on textile or non-textile sheets by means of the transfer printing process, wherein dyestuffs containing mercapto, hydroxyl and/or amino groups and applied to sheets by means of the transfer printing process are fixed by the action of isocyanates or masked isocyanates, which are applied to the sheets before, during, or after the dyestuff transfer.

摘要:
The invention relates to water-insoluble azo dyestuffs of the formula ##SPC1##In which A represents the residue of a diazo component of the azobenzene series, R.sub.1 a hydrogen atom or an alkyl group which may be substituted which may be substituted, R.sub.2 an alkyl group which may be substituted, R.sub.3 represents a divalent organic residue which together with the grouping ##EQU1## may form a 5- to 7-membered heterocycle, and X represents a hydrogen atom or an alkyl, alkoxy, aryloxy or arylmercapto group. The dyestuffs dye polyester fibre in orange, red or blue shades with good fastness: the use of such succinimido containing azo dyestuffs in imparting blue to red color to fibers or fabrics of wool, cellulose triacetate, polyamides and polyesters. The dyeings display excellent fastness to light, sublimation and abrasion on polyester fibers.

摘要:
The invention describes a process for the discontinuous aftertreatment of synthetic hydrophobic textile material, especially polyamide or polyester textile material, which is dyed preferably from an organic liquor with disperse dyestuffs containing hydroxyl and/or amino groups, with chemical fixing agents such as isocyanates, masked isocyanates, acid halides or acid anhydrides, from chlorinated aliphatic hydrocarbons, especially perchloroethylene, at temperatures above 80.degree.C, and subsequently rinsing and drying this material on which dyeings are obtained that are fast to water, solvents, light and are also very fast to sublimation.
