摘要:
Disclosed are basic dyes, e.g., azo dyes and anthraquinone dyes free from sulphonic acid groups and which contain, as characteristic group, a group of the formula ##STR1## in which R and R.sub.1, independently, are substituted or unsubstituted C.sub.1-4 alkyl or are linked to form a ring, orOne of R and R.sub.1 is --NH.sub.2 or C.sub.1-4 alkoxy, the other substituted or unsubstituted alkyl,R.sub.2 and R.sub.3, independently, are hydrogen or C.sub.1-4 alkyl,Y is a bridging group,Q is unsubstituted or substituted phenyl, biphenylyl, naphthyl or ##STR2## in which R.sub.7 is ##STR3## where R.sub.8 ic C.sub.1-4 alkyl, andA.sup.- is an anion. These dyes are useful for the dyeing and printing of polymers and copolymers of acrylonitrile and asymmetrical dicyanoethylene as well as polyesters and polyamides modified to contain acid groups. The dyes build-up well and exhibit good pH stability and stability to boiling. The obtained dyeings are level and possess good fastness to light, wet treatments, solvents, heat treatments and cross-dyeing.
摘要:
Water-soluble dyestuffs of the general formula ##EQU1## WHEREIN F represents the radical of a water-insoluble anthraquinone dyestuff, X represents an oxygen atom, a sulfur atom or a nitrogen atom which is substituted by a hydrogen atom, a lower alkyl, phenyl, lower acyl or sulfonyl group and Me represents an alkali metal or ammonium ion made by solubilizing insoluble dyestuffs which may be indigo, nitro, azo, imide, anthraquinone, oxazine, thiazine, dioxazine, quinoline, methine, polymethine or phthalocyanine dyestuffs. The water-soluble dyestuffs are adapted to be used in dyeing and printing synthetic fibers and are characterized by the fact that they can easily be converted during the process of dyeing to the original water-insoluble dyestuffs by the influence of heat. They are especially useful for the dyeing of polyester in which material they yield deep dyeings.

摘要:
An improvement in the process for the manufacture of 1-amino-2-alkoxy-4-hydroxyanthraquinones by reaction of primary, saturated, linear or branched aliphatic alcohols, which may contain further substituents, with 1-amino-2-phenoxy-4-hydroxyanthraquinone or 1-amino-2-methoxy-4-hydroxyanthraquinone in the presence of alkaline reagents, which consists in carrying out the reaction in the presence of polyethylene glycols of molecular weight above 150. The presence of the polyethylene glycol facilitates the reaction and as a result high yields of reaction product are obtained even with alcohols which react incompletely, if at all, in prior processes.
