Abstract: A basic azo dye of the formula

WHEREIN: R1 is methyl or ethyl, R2 is amino or a substituted amino radical, X is an anion, Y is the radical of the formula

R3 being cyclohexyl, p-methoxyphenyl, p-ethoxyphenyl or pmethylphenyl, R4 being methyl, ethyl, butyl, p-methoxyphenyl or p-ethoxyphenyl and R5 being methyl, ethyl or butyl. These dyes are useful in dyeing textile material of an acrylonitrile polymer or an anionically modified polyester in blue and violet shades with good light and wet fastness properties.

Abstract: Water-soluble disazo dyes of the pyrazole series of the formula

A and B each being hydrogen, methyl or phenyl; X being a phenyl or naphthyl radical; Y being a divalent phenylene or naphthylene radical; R being hydrogen or an organic radical; and n being 1 or 2. The dyes are especially suitable for dyeing and printing natural and synthetic polyamides and basified textile material and also for dyeing cellulose fibers, particularly when they contain reactive radicals.
