  • Patent number: 8697792
    Abstract: The invention relates to colored and/or fluorescent copolycondensates which are obtained by reaction of colorants substituted by at least two reactive groups which do not interfere with one another, with selected cyclic dicarboxylic acids (especially 1,4-cyclohexanedicarboxylic acid), aliphatic diols (especially ethylene glycol), cyclic diamines (especially isophoronediamine) and/or amino acids in particular amounts.
    Type: Grant
    Filed: September 15, 2010
    Date of Patent: April 15, 2014
    Assignee: BASF SE

  • Patent number: 8691002
    Abstract: 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.
