Abstract: Concentrated leuco indigo solutions useful for dyeing cellulosic textile material consist essentially of from 25 to 55% by weight of leuco indigo in the form of the leuco indigo salt, an amount which is essentially stoichiometrically sufficient to convert the leuco indigo into the neutral leuco indigo salt of a mixture of at least two alkali metal hydroxides wherein none of the alkali metal hydroxides accounts for more than 70 mol %, and water.

Abstract: Concentrated leuco-indigo solutions consisting essentially of 25-55 wt. % leuco-indigo in the form of a salt of a mixture of at least two alkali metal hydroxides containing not more than 70 mol. % of any one metal hydroxide, in the stoichiometric amount required for conversion of the leuco-indigo into the neutral indigo salt, together with water. Independent claims are also included for a process for the production of leuco-indigo solutions by catalytic hydrogenation of a 20-30 wt. % aqueous indigo suspension containing 4-10 wt. % alkali metal hydroxide mixture as defined above, after which the leuco-indigo content is adjusted to the required level by: (a) adding more indigo and optionally more alkali and continuing the hydrogenation; or (b) evaporation of the solution.
