| titleOfInvention | The method of producing pigment preparations PL |
| abstract | 1. Method for the production of pigment preparations by depositing a nitrosated iron complex of 2-naphtholsulfonic acid-6 on an aluminum carrier, characterized in that aluminum hydroxide and / or basic aluminum carbonate in a mixture with alkali or ammonium aromatic salts are used as the carrier carboxylic acids, the aluminum hydroxide and / or basic aluminum carbonate being pre-dispersed in an aqueous or a water-solvent medium, optionally in the presence of auxiliaries, the dye being introduced into the reaction zone, preferably in the form of a solution, in an amount of at least 5 parts per 100 parts by weight of aluminum hydroxide and / or basic aluminum carbonate and alkali metal or ammonium salts of aromatic carboxylic acids, preferably sodium benzoate, in an amount of less than 100 parts by weight per 100 parts by weight of aluminum hydroxide and / or basic aluminum carbonate, keeping all at a temperature below 100 ° C , preferably 10-50 ° C and pH 3.0-8.0, preferably 4.5-5.5, and the product obtained is isolated from the reaction medium, preferably washed with water, optionally dried and, if necessary, ground.
