具有季铵化杂环重氮成分基团的偶氮染料和偶联成分基团的氨基上的任选取代的芳氧基烷基取代基

Azo dyes having a quaternized heterocyclic diazo component radical and an optionally substituted aryloxyalkyl substituent on the amino group of the coupling component radical
摘要：
Basic dyes free from sulfo groups of the formula ##STR1## in which Q signifies an unsubstituted or substituted phenyl or naphthyl radical,R.sub.1 and R.sub.2 signify hydrogen, unsubstituted or substituted alkyl, phenyl or cycloalkyl,R.sub.3 signifies hydrogen, unsubstituted or substituted alkyl or phenyl,the Z containing group signifies a heterocyclic diazo radical containing a quaternary ammonium group,R.sub.4 signifies unsubstituted or substituted alkyl, alkenyl, cycloalkyl or alkoxy,x signifies 1 to 3,A.crclbar. signifies an anion, andD signifies an unsubstituted or substituted phenylene or naphthylene radical are useful for dyeing and printing homo- and co-polymers of acrylonitrile and asymmetrical dicyanoethylene and synthetic polyamides and polyesters modified to contain acid groups. The obtained dyeings are level and fast to light and wet treatments.
