Abstract

3654. Ransford, R. B., [Cassella & Co., L.]. Feb. 16. Dyeing.-Deep blue shades fast to washing and light are produced on cotton by diazotizing and developing on the fibre with #-naphthol the polyazo dyes which are obtained by combining diazotized 2 : 4 : 8-naphthylamine disulphonic acid with alpha-naphthylamine, again diazotizing, combining the product with ClÞve's alpha-naphthylamine sulphonic acid, again diazotizing, and, finally, combining the product with bases of the benzene series, such as p-xylidine.
