Abstract

Dyes are made by condensing halogenated naphthoquinoneimides with ammonia, amines, polyhydric alcohols or ethers thereof which contain a free alcoholic hydroxy group, phenols, or thiophenols. The condensation may be carried out in a solvent, which may be an excess of the second reactant, and in presence of alkali metal hydroxides, carbonates, bicarbonates, acetates, boric acid, copper or copper salts. The products may be converted to leuco-compounds. In examples, a brominated naphthoquinoneimide is reacted with (1) ammonia, (2) dimethylamine, (3) aniline, (4) p-toluidine, (5) o-anisidine, (6) aminohydroquinone dimethylether, (7) monoethylaniline, (8) benzidine, (9) phenol, (10) p-thiocresol, (11) monoethanolamine, (12) hexahydroaniline, (13) 2-amino-1-butanol, (14) 2-amino-2-methyl-1- propanol, (15) ar. tetrahydro-b -naphthylamine, (16) p-aminoacetanilide, (17) glycol monoethyl ether, (18) glycerol, (19) cresidine, (20) aniline. Also in examples, a chlorinated naphthoquinoneimide is condensed with aniline. The naphthoquinoneimides are defined as the intermediate reduction products of dinitrinaphthalene, and the halogenated bodies may be prepared according to Specification 606,008.
