Abstract
26,457. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. Dec. 5. Dyes, artificial.-Aluminium and other lakes are produced by known processes from the azo dyes obtained by combining diazo compounds with acidylized 1 : 8-amidonaphthol sulphonic acids, such as 1 8-acetylamido- or benzoylamido-naphthol-3 : 6- or 4 : 6-disulphonic acid or -4-monosulphonic acid. In examples, the diazo compounds of o-amidobenzene sulphonic acid, p-chloraniline 1 : 3 : 8-naphthylamine disulphonic acid, dianisidine, and amidoazobenzene disulphonic acid are mentioned.
