Abstract: Red monoazo dyestuffs from diazotized 1-aminobenzonitrile or 1-amino-4-, 5- or 6-halo-benzonitrile and 2-amino-8-hydroxynaphthalene-6-sulfonic acid. These dyes are particularly distinguished by their good migration and leveling properties and excellent fastness to light. Said dyestuffs are moreover suitable for obtaining very even combination dyeings together with known blue, yellow and orange acid dyestuffs. These dyestuffs are particularly suited for the dyeing of carpeting, upholstery fabrics and drapery materials.
