Abstract

25,816. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. Nov. 30. Dyes, artificial. -Monoazo dyes are obtained by combining the diazo compounds of 6-nitro or 6-halogen derivatives of 4-nitro-2-aminophenol, e.g. picramic acid, with p-chlorphenol or its homologues. The products give known shades on wool with bichromate. The dyeing is preferably effected in one bath with dyes and bichromate and acetic acid. Specification No. 3698, A.D. 1877, is referred to.
