Abstract

1329623 Dyes of the 2,4-hydroxyquinoline series BADISCHE ANILIN- & SODAFABRIK AG 19 April 1971 [25 Feb 1970] 22508/71 Heading C4P The invention comprises dyes of formula where R<SP>1</SP> is a halogen atom or a nitro group; n is 0, 1 or 2; =CR<SP>2</SP>R<SP>3</SP> is such that denotes an aldehyde or ketone and either CR<SP>2</SP>R<SP>3</SP> denotes a 5- or 6-membered carbocyclic or heterocyclic ring which may bear condensed rings or R<SP>2</SP> is H, an aromatic carbocyclic or heterocyclic radical or optionally substituted C 1 -C 3 alkyl and R<SP>3</SP> denotes an optionally substituted hydrocarbon radical. The dyes may be prepared by reacting a hydrazone of formula with an aldehyde or ketone of Formula IV in an organic solvent. The dyes may be used for - colouring printing inks, and coating compositions and for mass-colouring polymers in yellow to red shades.
