Abstract

Dyeing polyamides before forming is carried out by dyeing at elevated temperature in weakly acid to strongly alkaline medium in aq. solutions of a alcohols that are to a limited extent water soluble, with vat dyes and in the presence of formaldehyde sulphoxylate and a borohydride, fixing dyes by oxidising, rinsing, saponifying or damping, and subsequently shaping dyed chips or films. Vat dyes are suitably applied in stable leuco form. Dyeings have brilliance and transparency of fast dyeings from aq. bath.
