Abstract

1,272,819. Monoazo dyes. BADISCHE ANILIN- & SODA-FABRIK A.G. 24 Sept., 1969 [25 Sept., 1968], No. 46933/69. Heading C4P. The invention comprises monoazo dyes of formula wherein A is an optionally substituted arylene or aralkylene radical; n is 0, 1 or 2 and Z is the radical of a coupling component. Suitable radicals Z include anilines, aminonaphthalenes, indoles, pyrazolones, naphthols, phenols, quinolines, acylacetarylamides pyrazoles or perinaphthindanedione 1,3. The coupling components may also bear substituents e.g. halogen atoms, alkyl groups, sulphone, sulphonamido, carbalkoxy or acylamino groups. The dyes may be obtained by diazotization or coupling or alternatively a compound of the formula may be sulphonated by conventional methods. The dyestuffs give greenish yellow to violet shades on wool or synthetic polyamide fibre materials.
