Abstract

254,578. Carpmael, W., (Farbenfabriken vorm. F. Bayer & Co.). Oct. 29, 1925. Azo dyes.-The diazo compounds of as-m-xylidine and its substitution products are coupled with 2: 3-oxynaphthoyl-as-m-xylidines, either in substance to form pigment dyes, or on the fibre to yield fast red shades. The following components are specified :-as-m-xylidine, 6-nitro- or 6-chlor- 4-amino-1 : 3-dimetbylbenzene, 2 : 3 - oxynaphthoyl-m-xylidine, 2 : 3-oxynaphthoyl-1<1> : 3<1>-dimethyl-6<1>-nitro-4<1>-aminobenezene. Specifications 6379/12 and 17279/13, [Class 15 (ii), Dyeing, Processes &c. for], are referred to.
