Abstract

1376883 Water-insoluble monoazo dyestuffs CASSELLA FARBWERKE MAINKUR AG 16 Feb 1973 [18 Feb 1972] 7757/73 Heading C4P A monoazo dye has the formula where R is alkyl having 1-6 carbon atoms. The dyestuffs may be present in tautomeric forms. They may be used for dyeing or printing synthetic hydrophobic materials, and give a yellow or yellowish orange colour; suitable synthetic materials include polyesters, polyolefins, polyvinyl compounds, polyacrylonitrile, and cellulose acetates.
