Abstract: Novel dyes consist of 4,4'-bis-(7-amino-1-hydroxy-3-sulpho-2-naphthylazo)-stilbene-2,2'-disu lphonic acid tetra-(tertiary alkyl-alkanolammonium) salts of formula (I), where X = tertiary alkyl-alkanolammonium cation. Also claimed are: (i) the use of a liquid aqueous dye concentrate (A), containing 15-35 wt.% (based on (A)) dye and where 90-100 wt.% of the dye consists of (I), in an ink-jet process; and (ii) a method for printing a substrate by an ink-jet process using an ink prepared from (A).

Abstract: Useful for the ink jet process are dye preparations which contain from 0.01 to 10% by weight, based on the weight of the preparation, of a dye quantity which is from 90 to 100% by weight the dye of the formula I where Kat(+) is the equivalent of a metal or ammonium ion, from 0 to 15% by weight, based on the weight of the preparation, of one or more water-miscible organic solvents, and from 75 to 99.99% by weight, based on the weight of preparation, of water and which are essentially free of foreign salts, in the ink jet process.

Abstract: A process for the preparation of dyes which contain sulfonic acid groups and have a low electrolyte content, wherein an aqueous solution or suspension, which may or may not contain inorganic salts, of the dye containing sulfonic acid groups is (a) mixed with an amount, equivalent to the said dye, of a non-emulsifying, water-insoluble amine of a total of 12 to 40 carbon atoms, which forms, with the said dye, a salt which is sufficiently lipophilic for it to separate spontaneously from the aqueous phase, (b) the pH is brought to

Abstract: Stable, acid concd. solns. of mono and/or polyazo dyes in the form of the free acids, or alkali or ammonium salts, contain (A) 10-75 wt.% azo dye and (B) 90-25 wt.% solvent mixt. The solvent consists of (C) up to 100 wt.% water-soluble 1-6C carboxylic acid, (D) 0-90 wt.% water and (E) opt. other water-iniscible solvents and usual additives. The solvent compsns. are additional to those in parent patent in which (C) is 10-100 wt.% of water-miscible 1-3C carboxylic acid.
