Abstract

5245. Ransford, R. B., [Cassella & Co., L.]. March 3. Dyes, artificial; naphthazoles.-Azo dyes of analogous composition to those described in Specification No. 13,804, A.D. 1905, are obtained by first condensing in presence of a bisulphite one molecule of an aromatic aldehyde, such as maminobenzaldehyde, with 1 : 2-diamino-5-oxynaphthalene-7-sulphonic acid, and then condensing the product with one molecule of an azo dye-stuff containing an aldehyde group, such as that obtained from m - aminobenzaldehyde and 1: 4-naphthol sulphonic acid. The dyes so obtained may be combined with diazo compounds such as diazotized aniline, its homologues, or nitro derivatives, amidophenolether, or amidocresolether. The dyes may be diazotized on the fibre and combined with #- naphthol.
