  • Pigment compositions comprising pyrrolo[3,4-c]pyrroles
    Patent number: 8883889
    Abstract: The present invention relates to a process for the direct preparation of pyrrolo[3,4-c]pyrroles (DPPs) of the formula pigment compositions containing them and their use for coloring high molecular weight organic materials, such as plastics and paints. The obtained DPPs of the formula I possess a higher color strength, a higher chroma, a purer shade and a higher opacity versus corresponding commercially available DPPs.
    Type: Grant
    Filed: January 17, 2007
    Date of Patent: November 11, 2014
    Assignee: BASF SE
    Inventors: Vincent Ruffieux, Florence Modoux

  • Easily dispersible pigment composition
    Publication number: 20060178450
    Abstract: The present invention comprises a process for preparation of a stir-in pigment composition comprising a treatment of the pigment surface with at least one polymer and/or copolymer using water/solvent emulsion or pure organic solvent, miscible or non-miscible with the polymer or copolymer, or a mixture of these solvents or only water, in the presence of a surfactant, and optionally in the presence of a polar pigment derivative and/or a fluidiser and/or other components, said stir-in pigment composition as such as well as the use of this pigment composition for coloring high molecularweight organic materials.
