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:

Process for printing unions

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.

Sublimation transfer and diisocyanate fixation of amino- or

An azo compound free from sulfonic acid groups of the formula ##STR1## wherein D is the radical of a diazo component, A is a p-phenylene radical which may be substituted, X is an --NH-- group, a sulfur atom or an oxygen atom, Y is a cycloaliphatic radical containing up to 12 carbon atoms, X' is an --NH-- group, a sulfur atom or an oxygen atom, R.sub.1 is an alkyl radical which may be substituted, R.sub.2 is an alkylene radical which may be substituted and R.sub.3 is an organic radical, and mixtures of said azo compounds with one another, with or without other azo dyestuffs.

Cycloaliphatic dicarbonyl containing azo dyestuffs

Water-insoluble styryl dyestuffs of the formula ##STR1## in which X represents a cyano, carbo-lower alkoxy or phenylsulphone group, Y.sub.1 and Y.sub.2 each represents a hydrogen atom, an lower alkyl or lower alkoxy or phenoxy group, R represents a lower alkyl, phenyl-lower-alkyl, cyano-lower-alkyl, lower alkoxyalkyl or acyloxyalkyl group or a radical of the formula --A--S--B, and A represent a lower alkylene group that may be substituted by a lower alkanoyloxy or a benzoyloxy group and B represents a heterocyclic radical.

Certain benzazol-2-ylthio compounds

Disperse azo dyestuffs of the formula ##EQU1## where D is the residue of a diazo component of the benzene series,

Monoazo compounds

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.

Process for the manufacture of fast dyeings on synthetic hydrophobic

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.

Fluoro triazine containing water insoluble azo dyestuff

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.

Succinimido azo dyestuffs

Sublimation transfer and isocyanate fixation of amino- or

An azo dyestuff that contains at least one residue of a styryl dyestuff. The dyestuffs dye synthetic fibers in bright colours the dyestuffs are of the formula ##EQU1## wherein D is a heterocyclic diazo component, B is a coupling component, A is a para-phenylene and R.sub.1 and R.sub.2 are alkyl that may be substituted.
