Abstract
1425499 Metallized monoazo dyes BAYER AG 20 July 1973 [22 July 1972] 34674/73 Heading C4P New 1,2-cobalt complexes of monoazo dyes free of SO 3 H groups, of formula wherein X 1 , X 2 and X 3 are H, COOH or a non- ionic substituent, with the proviso that at least one is COOH, Y is H or a non-ionic substituent and R is an optionally non-ionically substituted alkylene, arylene or aralkylene group are prepared by coupling a diazotized 1-amino-2- hydroxybenzoic acid with an acetoacetylamine and treating the monoazo dye obtained with a cobalting agent. The complexes are used to colour natural and unmodified synthetic polyamide fibres in yellow shades.
