ABSTRACT:
Red monoazo dyestuffs from diazotized 1-aminobenzene-2-sulphonic acid-N-methyl-N-cyclohexylamide or 1-amino-4-, -5- or -6-methyl-benzene-2-sulphonic acid-N-methyl-N-cyclohexylamide and 2-amino-8-hydroxynaphthalene-6-sulphonic acid are disclosed which are particularly distinguished by their good migration and levelling properties and excellent fastness to light. Said dyestuffs are moreover suitable for obtaining very even combination dyeings together with known blue or yellow acid dyestuffs. These dyestuffs are particularly suited for the dyeing of carpeting, upholstery fabrics and drapery materials.
