摘要:
The present invention relates to the dyestuff of the formula I ##STR1## modifications of this dyestuff which are stable during dyeing, processes for the preparation thereof and their use for dyeing and printing synthetic fiber materials.
摘要:
The present invention relates to the .beta. and .gamma. modifications of the dye of the formula (I) ##STR1## as well as to a process for their preparation and their use for dyeing and printing textile materials of polyester and/or cellulose esters or blended fabrics of these materials and wool or cellulose.
摘要:
The .beta.-modification, which is stable under dyeing conditions, of the dyestuff of the formula ##STR1## is prepared by heating the .alpha.-modification, which is unstable under dyeing conditions, at temperatures of 60.degree. to 180.degree. C. and the .beta.-modification is useful in printing and dyeing fiber materials of cellulose esters, synthetic linear polyesters or mixed fabrics of the polyester fiber material with wool or viscose staple.
摘要:
The present invention relates to liquid or pulverulent textile dye preparations including one or more dispersants based on an alkoxylated and carboxylic-esterified castor oil of the general formula I ##STR1## where A, X.sup.1, X.sup.2, Z.sup.1, Z.sup.2, Z.sup.3, n.sup.1 and n.sup.2 are each as defined in Claim 1.
摘要:
The dyestuff mixture contains at least one dyestuff of the formula I ##STR1## and at least one dyestuff of the formula II ##STR2## wherein X and Y denote chlorine or bromine,R.sup.1 and R.sup.5 denote methyl or ethyl,R.sup.2 and R.sup.6 denote methyl, ethyl, n-propyl or i-propyl andR.sup.3, R.sup.4, R.sup.7 and R.sup.8 denote, for example, C.sub.1 - to C.sub.11 -alkyl, in the weight ratio of I:II=(5 to 95):(95 to 5), and is, for example, outstandingly suitable for dyeing synthetic fibres.
摘要:
A mixture of monoazo dyestuffs which contains one or more dyestuffs of the formula I ##STR1## and one or more dyestuffs of the formula II ##STR2## wherein R.sup.1 and R.sup.2 independently of one another each denote linear or branched alkyl with 1 to 6 carbon atoms, R denotes linear or branched alkyl with 1 to 5 carbon atoms and Hal denotes chloro or bromo, are outstandingly suitable for dyeing and printing hydrophobic materials.
摘要:
The present invention relates to mixtures of dyes of the general formula I ##STR1## in which R.sup.1 is hydrogen, halogen, (C.sub.1 -C.sub.4) -alkyl or (C.sub.1 -C.sub.4)-alkoxy;R.sup.2 is hydrogen, halogen, cyano, (C.sub.1 -C.sub.4)-alkyl, (C.sub.1 -C.sub.4)-alkoxy, (C.sub.1 -C.sub.4)-alkoxycarbonyl, (C.sub.1 -C.sub.4)-alkylcarbonyloxy or phenyl, which may be substituted or unsubstituted;R.sup.3 is hydrogen, (C.sub.1 -C.sub.4)-alkyl, (C.sub.1 -C.sub.4)-alkoxy or phenyl, which may be substituted or unsubstituted; andR.sup.4 is hydrogen, halogen, (C.sub.1 -C.sub.4)-alkoxy, phenylthio or phenoxy, which may be substituted or unsubstituted, to processes for their preparation and to the use of the dyes of the general formula I and their mixtures with one another for the dyeing and printing of textile hydrophobic synthetic fibre materials and blends thereof with natural fibre materials.
摘要:
