Abstract
Yellow anthraquinone pigments are made by heating o-phthaloyl dichloride with a mixture of different aminoanthraquinones containing at least 65% of 1-aminoanthraquinone, the molar ratio of phthaloyl dichloride to aminoanthraquinone mixture being within the range of about 1:1,5 to 1:2. Aminoanthraquinones other than 1-aminoanthraquinone which may be used are 2-amino-, 1:5-amino-chloro-, 1:8-amino-chloro-, 1:2-, 1:5- or 1:8-diamino- or 1-amino-5-benzoylamino-anthraquinones and mixtures of 1:6- and 1:7- or of 1:5- and 1:8-diamino-anthraquinones. Examples are given.
