Dyestuffs of the formula ##STR1## wherein R.sub.1 and R.sub.2 have the meaning given in the description,and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and fabrics of wool, silk or synthetic polyamide or polyurethane fibres, and for dyeing and printing natural or regenerated cellulose with dyeings and prints which are fast to washing. The dyeings obtained are distinguished by good fastness to light and wet processing.
摘要:
The invention is directed to reactive azo dyestuffs, free from anionic groups and which contain a basic group and a halogenotriazinyl radical and are of the general formula ##STR1## in which D is the radical of an organic azo dyestuff which is free from anionic groups and is preferably free from basic groups,B is a direct bond or a bridge member to a ring C atom of D,R.sub.1 is H, alkyl, aralkyl or aryl andW is a halogenotriazinyl radical containing a basic group; the dyestuffs are useful for the dyeing and printing of fibre materials containing cellulose.
摘要:
Reactive dyestuffs which are free from anionic groups, in particular sulpho and carboxyl groups, and contain a basic group and a halogenotriazinyl radical, and their use for dyeing and printing synthetic fibre materials. The dyeing obtained are distinguished by good fastness properties, of which, in addition to fastness to sublimation, light and dry cleaning, fastness to wet processing is to be singled out in particular.

Dyestuffs of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, m, n, p and X have the meaning given in the description,and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and woven fabrics of wool, silk or synthetic polyamide or polyurethane fibres, and for dyeing and printing natural or regenerated cellulose in dyeings and prints which are fast to washing. Blue dyeings and prints which are fast to light and wet processing are obtained.
摘要:
The present invention relates to dyestuffs of the formula ##STR1## wherein A=a substituent,B=H or a substituent, with the proviso that at least one of these substituents contains a fibre-reactive group, andR.sub.1 -R.sub.4 =H or a substituent.Preferred dyestuffs I are those which contain at least two groups which confer water-solubility, in particular sulpho, sulphato or carboxyl groups.

Reactive dyestuffs of the formula ##STR1## wherein R, D, R.sub.1, R.sub.2 and n have the meaning indicated in the description,and their use for dyeing textile materials containing hydroxyl groups and textile materials containing nitrogen, in particular for textile materials made of natural and regenerated cellulose, in red shades.
摘要:
The invention relates to new dioxazine reactive dyestuffs of the formula ##STR1## a process for their preparation and their use in dyeing and printing fibre materials which contain hydroxyl groups or amide groups.In formula (I):D denotes a radical of the dioxazine system of the formula ##STR2## the radicals Y, Z, A, X.sub.1 and X.sub.2 as well as m and n having the meaning indicated in the text of the application.The invention further relates to a process for the preparation of these new dioxazine reactive dyestuffs as well as their use in dyeing and printing fibre materials which contain hydroxyl groups or amide groups.
摘要:
Reactive dyestuffs of the formulaD-(T).sub.mwhereinD=the radical of an organic dyestuff,m=1-4 andT= ##STR1## wherein X and Y=a direct bond or a bridge member,W= ##STR2## acyl=an acyl radical and R.sub.1 -R.sub.3 =H, alkyl or aralkyl,the radical T being bonded, via X, to a C atom of an aromatic-carbocyclic or aromatic-heterocyclic ring of the chromophore and their use for dyeing and printing textile materials containing hydroxyl groups and textile materials containing nitrogen. The dyeings obtained are distinguished by good fastness properties, in particular excellent fastness to wet processing.
