New anthraquinone dyes, free of water-solubilizing groups such as -SO₃H and -CO₂H comprise anthraquinone substituted with one or more identical or different groups of the formula -NHSO₂R, wherein R is a substituted or unsubstituted linear, branched, cyclic or polycyclic alkyl group having up to 20 carbon atoms, and wherein the remaining nuclear aromatic carbon atoms of the anthraquinone may be substituted with substituents selected from the group: alkyl; the halogens F, Cl, and Br; cyano; nitro; aminosulfonyl; arylsulfonylamino; and -NHCOQ; wherein Q is hydrogen, an alkyl, an aryl, or a heterocyclic group.
These dyes have improved solubility, lowered melting point, and possess outstanding resistance to light-induced fading.
不含水溶解基团如-SO₃H 和-CO₂H 的新型蒽醌染料包括被一个或多个式-NHSO₂R 相同或不同基团取代的蒽醌,其中 R 是具有最多 20 个碳原子的取代或未取代的直链、支链、环状或多环烷基,蒽醌的其余核芳香碳原子可被选自以下组别的取代基取代:烷基;卤素 F、Cl 和 Br;氰基;硝基;氨基磺酰基;芳基磺酰基氨基;和-NHCOQ;其中 Q 是氢、卤素 F、Cl 和 Br;氰基;硝基;氨基磺酰基;芳基磺酰基氨基;和-NHCOQ:烷基;卤素 F、Cl 和 Br;氰基;硝基;氨基磺酰基;芳基磺酰基氨基;和 -NHCOQ;其中 Q 是氢、烷基、芳基或杂环基团。
这些染料具有更好的溶解性、更低的熔点和出色的抗光褪色性能。
