A type of sulfur dye, it is reduced with alkaline hydrosulfite NaOH + Na2S2O4 during dyeing. In general, many of them have better color tone and fastness than sulfur dyes. A representative dye is Hydron Blue (CIVat Blue 43 ), which is produced by melting carbazole indophenol, sodium sulfide Na2S , and sulfur S in ethyl alcohol. It dyes cellulose fibers such as cotton a deep blue color using a dyeing method similar to that of vat dyes. Its chemical structure is thought to be a complex polycondensation of carbazole indophenol. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
硫化染料の一種で,染色の際アルカリ性ハイドロサルファイトNaOH+Na2S2O4で還元して染める染料。一般に硫化染料より色調,堅牢度などが優れたものが多い。その代表的な染料はヒドロンブルー(C.I.Vat Blue 43)で,カルバゾールインドフェノール,硫化ナトリウムNa2S,硫黄Sをエチルアルコール中で融解して製造する。木綿などセルロース繊維を建染染料と同様な染法で濃青色に染める。化学構造は,カルバゾールインドフェノールが複雑に重縮合したものと思われる。
