摘要： Valuable 1:2-cobalt complex dyestuffs of the disazo compound of formula (1) ##STR1## had been found, in which R.sub.1 is hydrogen, halogen, nitro, lower alkyl or lower alkoxy, R.sub.2 is hydrogen, lower alkyl or lower alkoxy, R.sub.3 is hydrogen, lower alkyl or lower alkoxy, X is hydroxy or .beta.-sulfoethyl or a group of the formula ##STR2## wherein R.sub.4 is hydrogen or lower alkyl. The novel dyestuffs are well suitable for the dyeing of natural and synthetic polyamide fibres, especially in admixture with hydrophobic fibres, and also especially advantageously with other 1:2-chromium or 1:2 cobalt complex dyestuffs containing one or two sulfonic acid groups per dyestuff molecule, and yield even, strong dyeings of high fastness to wet processing and to use as well as to light. The novel cobalt complex dyestuff can be prepared by cobalting the above disazo compound (1) by means of a cobalt yielding agent.

These complexes are good dyes for nautral and synthetic polyamide fibers (e.g., wool, silk and Nylon) as well as for leather and light metals (e.g., aluminum)... The shades of the dyeings range from olive to yellowish-green to khaki-brown. The dyeings have notable fastness to light, wet treatments, rubbing and pressing and stability to alkalis and acids and satisfactory dischargeability. The dyes build-up on polyamides from neutral medium.

摘要： 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.
