The invention relates to basic bisazo compounds according to formula (I) wherein all substituents are defined as in Claim, their production, their use as dyestuffs as well as material dyed with these dyestuffs.

Basic bisazo compounds

The present invention concerns concentrated aqueous solutions of an anionic disazo dye, comprising salts and or the free acids of the anionic dye of the formula (I) and 2-(2-butoxyethoxy)ethanol and the use of these solutions for dyeing and/or printing hydroxyl-containing substrates and for producing inkjet inks.

Stable liquid formulation

The present invention concerns concentrated aqueous solutions of anionic disazo dyes, comprising salts and or the free acids of anionic dyes of the formula and 2-(2-butoxyethoxy) ethanol wherein the substituents are each as defined in claimand the use of these solutions for dyeing and/or printing hydroxyl-containing substrates and for producing inkjet inks.

Stable liquid formulations of anionic dyes

The invention relates to novel azo dyestuffs of formula (I), the use of such compounds and/or mixtures for printing recording materials, especially paper or papery substrates, textile fiber materials, plastic films and plastic transparencies by the inkjet printing process and also to the recording materials printed thereby 

Mono azo dyes

Disclosed are dyestuff mixtures for printing recording materials, especially textile fibre materials, paper and papery substrates and plastic films and plastic, as well as compositions suitable for ink-jet printing comprising a dyestuff of the formula (I) 

Use of a dyestuff for ink jet printing recording materials

Disclosed are novel dyestuff for printing recording materials, especially textile fiber materials, paper and papery substrates and plastic films and plastic transparencies by the inkjet printing process of the formula (I) wherein all substituents are defined in the claims. 

Acidic mono azo dyestuffs

The invention relates to the use of disazo compounds according to formula (I)wherein all substituents are as defined in claimsalts thereof and mixtures of these compounds for dyeing or printing organic substrates, to novel compounds, to the process for the production of these compounds and to substrates dyed or printed by these compounds.
