Abstract: The unions consist of a mixture of fibers which can be colored with disperse dyestuffs and fibers which can be colored with reactive dyestuffs. A printing paste containing:(a) at least one finely dispersed, water-insoluble azo dye-stuff of the formula: ##STR1## (b) at least one reactive dyestuff and (c) at least one non-ionic surfactant is used. The azo dyestuff of formula I is not prepared in the printing paste. It has a melting point between 220.degree. and 300.degree. C. In the formula, A, D and R have the meanings given in claim 1.In this way, prints are obtained, from which the non-fixed dyestuffs can easily be washed out and which have an excellent white ground. The build-up and fastness properties are good. The prints are very brilliant and deep in color, in particular in the field of orange and red shades.

Abstract: 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.

Abstract: Disperse azo dyestuffs of the formula ##EQU1## where D is the residue of a diazo component of the benzene series,A is the residue of a coupling component of the aminobenzene series,R.sub. 1 is alkyl, which can be substituted, e.g. by CN, Cl, OH, alkoxy, etc.,R.sub.2 is preferably alkylene,X is --NH--, --O-- or --S--,Y is preferably halogen, alkoxy, acyloxy, alkylcarbonyldioxy or alkylcarbamyloxy,R.sub.3 and ph are phenyl which can be substituted by nitro, halogen, alkyl or alkoxy and R.sub.3 can be H,dye polyester fibers in yellow, red or blue shades with good general fastness properties.

Abstract: 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.

Abstract: A water-insoluble disperse dyestuff of the heterocyclic azo series of the formula ##SPC1##Wherein A may be further substituted and one of the free valencies carries a fluorinated triazinyl group of the formula ##EQU1## wherein X is chlorine or fluorine. The dyestuff give fast yellow, red and blue shades on polyamide fibers.

Abstract: 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.
