  • Publication number: 20120129986
    Abstract: The use of an amine in a method to manufacture an aqueous suspension of mineral matter by dispersion and/or grinding in the presence of at least one acrylic polymer. The amine enables the quantity of polymer dispersant to be reduced. In a preferred embodiment the quantity of acrylic dispersant is reduced, whilst keeping the same mineral matter content, and maintaining or even improving the rheology of the suspension over time.

    Abstract: The present invention relates to a pigment composition composed of compounds of the formula (I), (II) and (III) with a novel crystal modification, to their preparation and to the use of this novel product as a pigment. For many applications of organic pigments, for example the coloring of metallic lacquers or the use thereof in color filters, a very high transparency is required. To produce color filters, for example, particularly fine pigments are used, in order to substantially rule out the particle scattering which leads to a lowering of the contrast ratio. The commercially available products, however, do not always meet all requirements of the art. More particularly, there was a need for improvement with regard to the transparency and the associated fineness of the pigment crystals, and also the color purity (chroma).
