ABSTRACT:
A basic dyestuff of the formula ##STR1## wherein R.sub.1 is hydrogen, alkyl of 1 to 5 carbon atoms, hydroxyalkyl of 1 to 4 carbon atoms, cyanoalkyl of 1 to 4 carbon atoms in the alkyl moiety or chloroalkyl of 1 to 4 carbon atoms, R'.sub.2 is phenyl or naphthyl or is phenyl or naphthyl substituted by alkyl of 1 to 4 C-atoms and/or alkoxy of 1 to 4 carbon atoms or nitro or cyano and/or chlorine, R.sub.5 is an optionally substituted alkyl or aralkyl radical, R.sub.6 and R.sub.7 being the same or different, each is hydrogen or an alkyl radical or, both together, substituents which complete to form an anellated aromatic ring, Y is a bivalent atom or a bivalent group necessary to complete a 5- or 6-ring, R.sub.10 is hydrogen, fluorine, bromine or chlorine or alkyl of 1 to 4 C-atoms and X.sup..sup.-`is an anion, which are suitable for the dyeing or printing of tannined cellulose fibers, silk, leather or fully synthetic fibers, such as acetate silk, polyamide fibers or acid modified polyamide or polyester fibers, especially of fibers which contain polyacrylonitrile or polyvinylidene cyanide. Their dyeings are in general very intense and have, for example, good fastnesses to light and to wetting processes, to chlorine and perspiration. They are resistant to a large degree to a change of the pH-value of the dyebath and can therefore be used both in a slightly acidic and in a strongly acidic bath. Wool is completely reserved by the dyestuffs under normal dyeing conditions.
