摘要

New inclusion compound, intercalation compounds or solid solutions which are the nickel salts or nickel complexes of a compound which, in one of its tauteromeric structures, corresponds to the formula ##STR1## which contain at least one other included compound, except for one composition of matter which consists of 45 to 82% by weight of azobarbituric acid/nickel 1:1 complex, 3 to 15% by weight of benzene- sulphonamide, 5 to 20% by weight of nickel acetate and 10 to 20% by weight of water and the use of these materials as pigments are disclosed.
