Abstract

28,925. Ransford, R. B., [Cassella & Co., L.]. Dec. 15. Azo dyes, forming on the material.-Bluishgreen to yellowish-green shades are obtained by diazotizing on the fibre and developing with phenylmethylpyrazolone, phenol, o- or m-cresol. or resorcin, the secondary disazo dyes produced by combining diazo bodies of the benzene or naphthalene series with cresidine, alpha-naphthylamine or its 6- or 7-sulphonic acids, rediazotizing and combining with an aminoaryl-8-oxy-1: 2- naphthiminazole sulphonic acid. Specification 1675/05 is referred to.
