Abstract

L'invenzione riguarda un procedimento per la preparazione d'un leucocolorante allo zolfo secco e idrosolubile (L), caratterizzato dal fatto che un colorante allo zolfo (S) viene fatto reagire in un mezzo acquoso e ad una temperatura superiore a 60°C, con una quantità efficiente (A) d'un composto carbonilico riducente, in presenza (B) d'un idrossido di metallo alcalino, ed eventualmente (C) d'un solfito e/o d'un bisolfito di metallo alcalino,ed i1 prodotto viene essiccato, l'essiccazione essendo effettuata per polverizzazione in un tempo di essiccazione inferiore a 4 minuti.I coloranti ottenuti sotto la forma leuco sono particolarmente appropriati per la tintura dei substrati fibrosi di poliammidi, specialmente della lana.
