New water-soluble azo cpds. (I-V) are of formulae (D1-N=N-R)(-N=N-D)m (I), (R-N=N-T-N=N-R)(-N=N-D)n (II), (R-N=N-T-N=N-K)(-N=N-D)n (III), (R-N=N-T-N=N-)2K (IV) or R-N=N-X(-N=N-T-N=N-)X-N=N-R (V) (in which D is the aromatic gp. of a diazo component of the benzene, naphthalene or diphenylamine series, which can contain 1 or 2 acid (SO3H) substits. D1 is as D or is the aryl gp. of a diazotised aminoazo cpd. T is the aromatic gp. of a tetrazo component of the benzene, naphthalene, biphenyl, diphenylamine, diphenylalkane, diphenyl oxide, diphenyl sulphide, azobenzene or stilbene series, which can have 1 or 2 acid (SO3H) substits. X is an aromatic gp. of the benzene or naphthalene series, which has a diazotised amino gp. and also a coupling position adjacent to an OH gp. K is derived from a coupling component from an aromatic (di)hydroxy cpd. of the benzene, naphthalene or diphenylamine series of an enolised or enolisable acylacetic acid deriv. R is derived from a coupling component based on a resorcinol resin RH (VI), approx. of formula (IV). m is 0-5, n is 0-2 and p is 0-3). (I-V) are specified for use as dyestuffs, esp. for dyeing and printing textiles of natural or regenerated cellulose, silk, wool, synthetic polyamide fibres, skins or esp. leather. They have equal affinity for all types of leather.
