Abstract

PROCEDE POUR METTRE DIRECTEMENT LA FLAVANTHRONE BRUTE SOUS UNE FORME PIGMENTAIRE TRANSPARENTE DE NUANCE VERDATRE FACILE A DISPERSER, PAR CONVERSION EN LE LEUCO, ISOLEMENT ET REOXYDATION DE CE DERNIER. L'OXYDATION DU LEUCO EST EFFECTUEE EN PRESENCE D'AGENTS TENSIO-ACTIFS EN L'ABSENCE DE FORCES DE CISAILLEMENT, OU SOUS L'ACTION DE FORCES DE CISAILLEMENT EN PRESENCE OU EN L'ABSENCE D'AGENTS TENSIO-ACTIFS. LE PROCEDE SELON L'INVENTION DONNE DIRECTEMENT DES PIGMENTS TRANSPARENTS FACILES A DISPERSER ET CONFERANT PAR EXEMPLE AUX RESINES SYNTHETIQUES OU PEINTURES A CUIRE AU FOUR DES NUANCES JAUNE-VERDATRE PURES.PROCESS FOR PUTTING THE CRUDE FLAVANTHRONE DIRECTLY IN A TRANSPARENT PIGMENTAL FORM OF A GREEN TINT EASY TO DISPERSAL, BY CONVERSION INTO LEUCO, INSULATION AND REOXIDATION OF THE LATTER. THE OXIDATION OF LEUCO IS CARRIED OUT IN THE PRESENCE OF SURFACTURING AGENTS IN THE ABSENCE OF SHEARING FORCES, OR UNDER THE ACTION OF SHEARING FORCES IN THE PRESENCE OR IN THE ABSENCE OF SHEARING AGENTS. THE PROCESS ACCORDING TO THE INVENTION DIRECTLY GIVES TRANSPARENT PIGMENTS EASY TO DISPERSAL AND FOR EXAMPLE GIVING SYNTHETIC RESINS OR OVEN-BAKING PAINTS PURE YELLOW-GREEN SHADES.
