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 leucoindigo solutions, comprising the following essential ingredients: 25-55 wt. % leucoindigo in the form of a leucoindigo salt, a mixture of at least two alkali metal hydroxides, whereby the respective proportion of each metal hydroxide does not exceed 70 mol % and the amount thereof corresponds to the stochiometrically required amount for the leucoindigo to be converted into said neutral leucoindigo salt, in addition to water. The invention also relates to the production of said leucoindigo solutions and the use thereof for colouring textile material containing cellulose.
