Title (EN) ORGANIC BLACK PIGMENTS AND THEIR PREPARATION
(FR) PIGMENTS NOIRS ORGANIQUES ET LEUR PRÉPARATION
Abstract:
(EN) A process for preparing a black colorant, preferably a black pigment, characterized in that a compound of the Formula (I) is reacted with a compound of the Formula (II) in a molar ratio of 1:2, in the presence of a catalyst which in water at 25 °C has a pK ≤ 4.5. For the definition of R1 to R7, refer to the description; preferably all are H. Likewise claimed are new crystal polymorphs obtainable by this process, and preferably single-phase mixed crystals. Also claimed are synergistic compositions. These compositions exhibit increased light stability in plastics stabilized with basic light stabilizers when they are pigmented with colorants of the invention rather than with known black pigments such as carbon black. The specification also relates, furthermore, to the use of the black colorants of the invention for coloring paints, printing inks and plastics in the mass, and to mulch film, instrument panels, woven fabrics, garden furniture items or elements for the construction industry that are pigmented with said colorants.
(FR) L'invention concerne un procédé de préparation d'un colorant noir, de préférence un pigment noir, caractérisé en ce qu'un composé représenté par la formule (I) est mis à réagir avec un composé représenté par la formule (II) selon un rapport molaire de 1/2, en présence d'un catalyseur qui dans une eau à 25 °C présente un pK ≤ 4,5. Pour la définition de R1 à R7, il faut se reporter à la description, tous de préférence représentant H. L'invention concerne également de nouveaux polymorphes cristallins pouvant être obtenus au moyen dudit procédé, et de préférence des cristaux mélangés en une seule phase. L'invention concerne en outre des compositions synergiques. Ces compositions présentent une stabilité à la lumière accrue dans des plastiques stabilisés au moyen de photostabilisateurs basiques lorsqu'ils sont pigmentés par les colorants de l'invention plutôt que par des pigments noirs connus, tel que le noir de charbon. La spécification concerne également l'utilisation des colorants noirs de l'invention pour colorer des peintures, imprimer des encres et des plastiques dans la masse, et pour des films de couverture, des panneaux d'instruments, des tissus tissés, des articles de meubles de jardin ou des éléments de l'industrie du bâtiment qui sont pigmentés par lesdits colorants.
