Abstract

There are described novel azo compounds and their preparations. These compounds are of the formula:- <IMAGE> where X is N or CR4 where R4 is a hydrogen atom or an optionally substituted alkyl or aryl group, Y is S<+>, NR<+>5, O<+> or N where R5 is an optionally substituted alkyl or aryl group, R1 is a substituted aromatic or heterocyclic group containing a ballasting group, R2 and R3 are each hydrogen atoms or alkyl groups having 1 to 4 carbon atoms, or R2 and R3 together with the nitrogen atom complete a heterocyclic ring, or one of R2 or R3 can be hydrogen and the other of R2 or R3 can be aryl, and T1 and T2 represent hydrogen atoms, or optional annelation or further substitution. These azo compounds are of use in photographic colour diffusion transfer processes.
