Disazo compounds containing a 6-acetoacetamide-1-naphthol-3-sulfonic derivative as coupling component

摘要

There are described azo compounds of the formula <IMAGE> wherein D1 and D2 are each the radical of a diazo component, R is C1-C4-alkyl or C1-C4alkyl substituted by C1-C4-alkoxy or halogen or is phenyl or phenyl substituted by C1-C4-alkyl, halogen or C1-C4 alkoxy, and Y is a basic or cationic group. These azo compounds can be used as dyes for dyeing and printing natural and synthetic, cationically dyeing substrates, particularly textile materials and paper.
