<p>This invention relates to new azulmic acids, stabilised by condensation with carbonyl compounds, containing from 0.5 to 55 per cent by weight of ionic groups of the formula (F1) in which R represents hydrogen, ammonium, one equivalent of a protonated or quaternised organic nitrogen base or of a sulphonium cation or one equivalent of a metal cation. and containing from 0.5 to 15 per cent by weight of groups formed by decarboxylation reactions of the formula (F2) and acid addition salts and complex compounds of these stabilised azulmic acids, and also mixed products of these stabilised ezulmic acids with additives. Furthermore, the invention relates to several processes for the preparing of said novel products and to their use for various purposes. Le A 17 040</p> |
