Patent GB-1016964-A (GB)
Title: Water-insoluble azo dyestuffs containing nitrophenyl-hydrazone residues
IPC: C09B43/00
Filed: 1963-07-24
Abstract: The invention comprises water-insoluble azo dyes free from water-solubilizing groups and containing in the diazo and/or coupling component at least one nitrophenylhydrazone residue linked to a carbon atom not already linked to an azo group.  The dyes are prepared by reacting an azo dye free from water-solubilizing groups but containing at least one aldehyde or ketone group linked to a carbon atom not already linked to the azo group with a nitro-phenylhydrazine. Alternatively the dyes are prepared by the usual coupling processes using components containing at least one nitro-phenylhydrazone group.  The dyes may be used as pigments in the spin-dyeing of synthetic fibres and to colour lacquers.  In examples the preparation of mono- and dis-azo dyes is described.
