Abstract

14,634. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. June 29. Dyes, artificial.-Lakes are produced by known processes from the azo dyes obtained by combining naphthol sulphonic acids, such as 1 : 4-, 1 :5-, or 2:8-naphthol monosulphonic acids, 2:6:8- or 1 : 3 : 8-naphthol disulphonic acids, with the diazo compounds of o-amidobenzene sulphonic acid, or of homologues or derivatives thereof, such as 1 : 2 : 4-, or 1 : 3 : 6 - amidobenzene disulphonic acids, toluidine sulphonic acid [NH2 : CH3 : SO3H = 1 : 4 : 6], acetylamidoamidobenzene sulphonic acid [NH2 : O2H3OÀNH : SO3H # 1 : 4 : 6], or the like. In examples, lakes of aluminium and barium are described. The lakes produced are generally orange, yellowish-red, or bluish-red, and are fast to light.
