Disazo dyes and their complex metal compounds. FARBWERKE HOECHST A.G. 26 Jan., 1970 [25 Jan., 1969], No. 3591/70. Heading C4P. The invention comprises water soluble disazo dyestuffs and their copper, cobalt, nickel or chromium complexes. The dyes in the metal free form have the general formula wherein; Y and Y1 each represent a grouping wherein Z represents an inorganic or organic group which can be split off by alkaline agents, Hal represents halogen and R1 represents hydrogen or C 1 -C 4 alkyl; A and A1 each represent an alkylene or cycloalkylene radical; n1 and n11 are each 0 or 1; m 1 and m 2 represent a number from 0-2, m 1 + m 2 being an integer of from 1-4; D and D1 each represent a radical of the benzene or napthalene series; X 1 and X 2 each represent hydrogen, hydroxy, alkoxy or carboxy. The dyes are obtained by coupling a coupling component of formula at the acetoacetylamino group with a diazo compound of an amine of formula and subsequently coupling the resulting monoazo dye with a diazo compound of an amine of formula The disazo dyes thus obtained are optionally metallized in the usual manner The dyes give brown, olive and grey shades on wool, silk, polyamide and polyurethane fibres, particularly natural or regenerated cellulose fibres.
