Abstract

Sulpho-free dis- or polyazo compounds in metal-free or 2:1 metal complex form of formula < IMAGE > in which A1 and A2 are metallised or metallisable groups, X and Y are conventional bridging groups A is < IMAGE > and R3 is alkyl or A together with R3 forms a phenyl ring R1 is an aromatic or heterocyclic coupling component group, n is at least 2, and Z is a basic or ammonium group. Novel azo compounds in 2:1 metal complex form are of formula II < IMAGE > in which R1, R3, A, Y, X, Z and n are as above defined and Me is a metal and novel azo compounds in metal-free form are of formula VIII < IMAGE > in which R10, R9, r, ring E, ring G and Y' are as defined in the specification and X and Z are as above. These azo compounds are useful in dyeing and printing on cotton, paper and leather.
