    摘要: A new dye based upon N-alkylated or N-hydroxyalkylated 8-amino-1-naphthol-3,6-disulfonic acid and 4,4'-diaminostilbene-2,2'-disulfonic acid, a procedure for synthesizing it and a procedure for utilizing it for coloring cellulosic substrates is disclosed. The naphthol compound is alkylated or hydroxyalkylated and coupled with the isolated tetrazonium salt of the diamine, and in a preferable embodiment sufficient of the sulfonic acid groups are neutralized to render the final dye water soluble. The procedure is preferably conducted in aqueous medium, and the substitution of the amino group of the naphthol compound is preferably effected with lower dialkyl sulfates or epoxides. The dye is particularly suitable for dyeing paper.

    摘要: A novel modified diarylide pigment contains (a) a pigment which is composed of a tetrazotized benzidine, coupled to an acetoacetarylide and/or a 1-phenyl-3-methylpyrazole-5-one, and (b) a water-soluble component obtained from a symmetric or asymmetric coupling product of a tetrazotized 4,4'-diamino-2,2'-stilbenedisulfonic acid and an acetoacetarylide and/or a 1-phenyl-3-methyl-5-pyrazolone. The novel pigments possess very good color strength, very good gloss characteristics and very good transparency, and exhibit improved printing characteristics, particularly in offset printing inks.
