Abstract

17,030. Ransford, R. B., [Cassella & Co., L.]. July 24. Azo dyes, forming on the material.-Blue shades are obtained by diazotizing on the fibre and developing with #-naphthol, trisazo dyes of the general formula where P=p-phenylene or a substituted p-phenylene, and X=a diazotizable amine, other than an aminonaphthol sulphonic acid, for example, p-xylidine, cresidine, or ClÞve's acid. Specifications 5112/92, 19,743/92, [both in Class 2, Acids and salts, Organic, &c.], and 9972/93 are referred to.
