Abstract

2-Aryloxyquinizarins, sulphonic acids thereof and lakes therefrom are obtained by treating 2-halogenquinizarins with aromatic phenols or substitution products thereof, with or without addition of copper or salts thereof, and in presence of alkaline agents, subsequently sulphonating, and converting with the aid of lake-forming metallic salts into pigment dyestuffs. According to examples 2-bromoquinizarin reacts with p-cresol, p-chlorphenol, p-hydroxybenzoic acid methyl ester and phenol, in alkaline medium, the products are sulphonated, and converted into lakes with aluminium or beryllium compounds; 2-chloroquinizarin is also specified.
