| titleOfInvention | Anthracene derivative |
| abstract | PURPOSE: To provide an anthracene derivative of a specified structural formula, which can be isolated as a leuko compd. and can be oxidized in a bath without using any special oxidizing agent to thereby well develop a color and dye fibers. n CONSTITUTION: An anthracene derivative represented by the formula can be obtd. by reducing 1-anilino-4-hydroxyanthraquinone with a reducing agent such as sodium dithionate in the presence of an alkali such as potassium hydroxide, sodium hydroxide or sodium carbonate in water, an alcohol or a mixture of water and an alcohol, or in the presence of zinc in an aq. hydrochloric soln. When 0.1W2.0wt% ammonia, benzyl alcohol or a mixture of ammonia and benzyl alcohol is present in a bath in dyeing fibers with said anthracene derivative, the fibers can be well dyed. n COPYRIGHT: (C)1987,JPO&Japio |
