An accurate characterisation of the organic dyes used in artworks, especially those made of paper, is an important factor in designing safe conservation treatments. In the case of synthetic organic dyes used in modern works of art, for example, one frequently encountered difficulty is that some of these dyes are not still commercially available. Recognizing this problem, the authors of this paper present the results of an analysis of UV-Vis-NIR fibre optic reflectance spectra of 82 samples of dyed paper prepared with 41 dyes. The samples come from a historic book, The Dyeing of Paper in the Pulp, which was published by Interessen-Gemeinschaft (I.G.) Farbenindustrie in 1925. The dyes used in the paper pulp belong to the azo compounds, acridine, anthraquinone, azine, diphenylmethane, indigoid, methine, nitro, quinoline, thiazine, triphenylmethane, sulphur and xanthene classes.
对艺术品中使用的有机染料（尤其是那些纸质的有机染料）进行准确的描述，是设计安全保存处理方案的重要因素。例如，在现代艺术品中使用的合成有机染料，一个经常遇到的困难是，其中一些染料不再商业供应。认识到这个问题，本文作者展示了对 82 个用 41 种染料染色的纸样品的紫外可见近红外光纤反射光谱分析结果。这些样品来自一本历史书籍《纸浆中的纸染色》，该书由 Interessen-Gemeinschaft（I.G.）Farbwerke 于 1925 年出版。纸浆中使用的染料属于偶氮化合物、吖啶、蒽醌、嗪、二苯甲烷、靛蓝、甲川、硝基、喹啉、噻嗪、三苯甲烷、硫和呫吨类。
