Abstract
Dyes are made by condensing an aminoanthraquinone of the formula <FORM:0630525/IV (c)/1> where X is chlorine, bromine, or sulpho, Y is chlorine or bromine, and one Z is sulpho, the other being hydrogen, with a hydroaromatic amine of the formula <FORM:0630525/IV (c)/2> where R stands for H, methyl, or ethyl, or where two adjacent R's form starting points of an aromatic or hydroaromatic nucleus, the other R's being hydrogen. Where X is chlorine or bromine, it is subsequently replaced by sulpho by reaction with an alkali metal sulphite. Various mono-, di-, and tri-alkyl cyclohexylamines are specified, and also 1-amino-or 2-amino-1.2.3.4-tetra- or decahydronaphthalene. In examples: (1) 1-amino-4-bromanthraquinone - 2.8 - or 2.5 - disulphonic acid sodium salt is condensed with aminocyclohexane, 1-amino-2.4-diethylcyclohexane, or the corresponding dimethyl body; (2) 1-amino-4 - chlor - anthraquinone - 2.5 - disulphonic acid sodium salt is condensed with each of the possible monoethyl- or monomethyl-cyclohexylamines; (3) 1-amino-4-bromanthraquinone-2.5- or 2.8-disulphonic acid potassium salt is condensed with 3.4-dimethyl- or diethyl-3.4-methylethyl- or 3.5-dimethyl-cyclohexylamine; (4) 1-amino-2.4-dibromanthraquinone-5-sulphonic acid potassium salt is condensed with 1-amino-2.4.6-trimethylcyclohexane or its isomers, followed by reaction with a sulphite; (5) 1-amino-4-bromanthraquinone-2.5- or 2.8-disulphonic acid potassium salt is condensed with 1 - amino - 3.4.5 - trimethylcyclohexane; (6) 1 - amino - 4 - bromanthraquinone - 2.8 - or 2.5-disulphonic acid potassium or other salt is condensed with 2-amino-1.2.3.4-tetrahydronaphthalene; (7) 1 - amino - 4 - bromanthraquinone-2.5-disulphonic acid is condensed with 1 - amino - 1.2.3.4 - tetrahydronaphthalene, or 1- or 2-amino-decahydronaphthalene. Specification 276,408, [Class 2 (iii)], is referred to.
