    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).

  • Publication number: 20120263769
    Abstract: The present invention provides an ultraviolet absorber-including clay mineral, which allows an ultraviolet absorber to be blended, as a powder component, into cosmetic preparations, can effectively absorb a wide range of ultraviolet light, and has excellent inclusion amount and inclusion strength; and cosmetics containing the same. The ultraviolet absorber-including clay mineral is characterized in that a polybase and an anionic ultraviolet absorber are intercalated between the layers of a water-swellable clay mineral. The polybase is preferably a polymer having a nitrogen-containing group that can become a cation. The anionic ultraviolet absorber is preferably one or more selected from 2-phenylbenzimidazole-5-sulfonic acid, 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid, and their sodium salts.
