摘要
皮革黑ＧＮ 是无致癌毒性的联苯胺的代用染料，本文研究了其在皮革染色中的应用性能。结果表明，该染料不仅可替代直接黑ＢＮ（Ｃ．Ｉ直接黑３８）和直接耐晒黑Ｇ（Ｃ．Ｉ直接黑１９） ，而且其性能和进口皮革黑染料相当。借助于稀土助染和复染可以解决皮革染色中存在的染黑不黑的问题。
The applicable properties of Leather Black GN, which is a replacement dyestuff of benzidine and causes no cancers is investigated in this paper. Results show it can not only replaces Direct Black BN (Direct Black C.I 38) and Litht_fast Direct Black C.I 19), but also has the equal properties to the foreign black dyestuffs. Problems such as not black enough when blackened in leather dyeing' could be solved with the help of rare_earth dyeing auxiliary and repeatable dyeings.
