Abstract

L'invention a trait à la chimie du colorants. Elle concerne de nouveaux colorants azoïques et leur procédé de production par diazotation d'amines aromatiques, puis copulation en milieu acide avec des copulants naphtaléniques, mais de préférence avec l'acide y, en milieu aqueux ou aqueux-organique. Les colorants azoïques de l'invention conviennent pour la teinture de matières fibreuses naturelles et synthétiques.The invention relates to the chemistry of dyes. It relates to new azo dyes and their production process by diazotization of aromatic amines, then coupling in an acidic medium with naphthalene couplers, but preferably with γ-acid, in aqueous or aqueous-organic medium. The azo dyes of the invention are suitable for dyeing natural and synthetic fiber materials.
