A general term for dyes that have a condensed polycyclic quinone structure related to anthraquinone or alizarin. In terms of dyeing, they are classified into mordant dyes, acid mordant dyes, acid dyes, disperse dyes, cationic dyes, vat dyes, and reactive dyes, and each occupies an important position in its own field. They have a relatively simple structure, can produce deep hues, generally have vivid colors, and are characterized by excellent fastness, especially fastness to sunlight. In the dye industry, they occupy an important field along with azo dyes. Their chemical structures are the most complex in the vat dye category, and range from simple ones such as acylaminoanthraquinones to anthrone derivatives such as pyranthrone, violanthrone, flavanthrone, and pyrazoleanthrone, which form new nuclei at the 1,9 positions of anthraquinone. Some examples are shown below. Source: Morikita Publishing "Chemical Dictionary (2nd Edition)" Information about the Chemical Dictionary 2nd Edition |
アントラキノンやアリザリンに関連した縮合多環キノン構造をもつ染料の総称.染色的には,媒染染料,酸性媒染染料,酸性染料,分散染料,カチオン染料,建染め染料,および反応染料などに分類され,それぞれの分野で重要な地位を占めている.比較的簡単な構造で,深い色相が得られ,また,一般に色調は鮮明で,しかも諸堅ろう度,とくに日光堅ろう度のすぐれていることが特徴である.染料工業界において,アゾ染料とともに重要な分野を占めている.それらの化学構造は,建染め染料に属するものがもっとも複雑で,アシルアミノアントラキノンのような単純なものから,アントラキノンの1,9位において新しい核を形成しているピラントロン,ビオラントロン,フラバントロン,ピラゾールアントロンなど,アントロン誘導体のものまできわめて広大な範囲にわたっている.以下にいくつかを例示する. 出典 森北出版「化学辞典(第2版)」化学辞典 第2版について 情報 |
