The invention relates to basic mono- and bisazo compounds according to formula (I) wherein all substituents are defined as in Claim 1, their production, their use as dyestuffs as well as material dyed with these dyestuffs.

Basic mono- and bisazo compounds

A composition for printing recording materials comprising a) at least one temporarily water-soluble dye with one SOCHCOOM group being present in the molecule; b) water or a medium including a mixture of water and an organic solvent, an anhydrous organic solvent or a solid having a low melting point, and c) optionally further additives.

Composition for printing recording materials

The present invention relates to novel 1:2 chromium complex dyes, processes for their preparation and their use for dyeing or printing fiber materials containing hydroxyl groups or containing nitrogen. The present invention relates to a 1:2 chromium complex dye of formula (I):wherein all substituents are as defined in the claims, a process for their preparation and their use for dyeing or printing fiber materials containing hydroxyl groups or containing nitrogen.

1:2 chromium complex dyes

Water-soluble stilbene dyes, their preparation and use

Red acid dyes for injet printing and paper dyeing

Water-soluble red acid dyes, their preparation and use

Basic azo compounds of formula I are suitable for coloring or printing especially of paper and leather.

Basic azo compounds, their production and use

Compounds of Formula I ##STR1## wherein the substituents are as defined in the description, a process of manufacture thereof and a process of dyeing employing said compounds.

Basic monoazo compounds

The invention relates to mixtures comprising

Mixtures of copper phthalocyanine and copper-containing azo dyes, their

Basic sulpho group-containing disazo compounds which are metal-free, correspond to the formula ##STR1## in which the symbols are as defined in claim 1. These compounds, in form of their water-soluble salts, and preparations thereof are used for dyeing or printing cationically dyeable materials such as hydroxy group- or nitrogen-containing organic substrates of which textile material comprising natural or synthetic polyamide or natural or regenerated cellulose and especially cotton, leather and paper are preferred. Furthermore, they can be used for the preparation of inks in a conventional manner.

Basic disazo compounds containing sulphonic acid groups

The disazo dyestuffs and mixtures thereof, of the general formula I ##STR1## wherein the symbols R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and M possess the significances given in claim 1, are eminently suitable for dyeing or printing organic substrates containing hydroxyl, thiol or amido groups, especially cotton or paper.

2,2'-disulfo-4,4'-substituted triazinylaminophenyl disazostilbenes

Sulpho group-containing dioxazine compounds corresponding to the formula ##STR1## in which the symbols are as defined in the specification, and salts thereof as well as dyeing preparations thereof are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, optionally combined with a special after-treatment of the dyed or printed textiles thus obtained to improve their wet fastness properties. Most preferred substrates are textile material containing or consisting of cellulose and paper.

Sulfo group containing triphendioxazines having at least one

Compounds of the formula ##STR1## and salts thereof, wherein

Substituted

Compounds of the formula ##STR1## in free acid or salt form and internal, external and acid addition salts thereof, wherein

Sulfo group-containing monoazo compounds having an unsubstituted or

Compounds of the formula ##STR1## wherein each R.sub.1 is independently hydrogen, C.sub.1-4 alkyl or C.sub.1-4 alkyl monosubstituted by hydroxy, halo, cyano or C.sub.1-4 alkoxy,
