    Abstract: Betainic complex azo dyestuff-cobalt compound consisting essentially of, per molecule:A cobalt atom;One molecule of a colorless tridentate organic ligand which is coordinatively bound to said cobalt atom by way of three nitrogen atoms which is free from ionogenic groups which do not partake in complex formation, each of said nitrogen atoms participating in the formation of a 5- to 6- membered ring of which said cobalt atom is a member; andOne radical of a mono- or dis- azo dyestuff capable of forming a bicyclic metal complex with cobalt and containing one sulphonic acid group, whereby a complex dyestuff-cobalt compound is formed which has the character of an inert salt (betaine), are disclosed. These compounds are useful for the dyeing and/or pigmenting of polymeric and copolymeric organic material, e.g., lacquers, synthetic plastics or spinning masses, as well as for the dyeing of polyamide fibers from weekly acid bath.

    Abstract: A process for dyeing wool or wool/synthetic blends with 1:1 metal complex dyes or acid metal-free wool dyes from a strongly acid aqueous bath, which comprises dyeing said material in the presence of(a) a quaternization product of a polyalkylene oxide adduct of a fatty amine containing at least 16 carbon atoms and 15 to 100 moles of alkylene oxide, and(b) a free or etherified N-methylolurea or N-methylolmelamine.
