Abstract

Abstract Theft of archival documents constitutes a serious problem for archives. A possible solution to this problem lies in labelling these documents with codes that are invisible to the naked eye. A possible method could involve use, e.g. of the oxides of lanthanum, dysprosium, samarium, gadolinium and niobium, which have good responses in the XRF spectrum and are normally not present in archival materials. This study is concerned with the impact of these oxides on the properties of lignocellulosic materials. The identification tags were printed on three different kinds of paper supports (Whatman No. 1 filter paper, paper according to ISO 9706 and sulphite pulp). The colour change, average degree of polymerisation, the pH values of an aqueous extract and selected mechanical properties after application of the tag and artificial ageing were studied on all the samples. The measurements showed that the studied oxides do not have a negative effect on the monitored properties of the paper supports and do not affect their long-term ageing behaviour.

基于过渡金属和内部过渡金属氧化物的档案文件识别标签——对纸张支撑的影响

摘要档案文件被盗是档案馆面临的一个严重问题。这个问题的一个可能解决方案是用肉眼看不见的代码给这些文件贴上标签。一种可能的方法可能涉及使用，例如镧、镝、钐、钆和铌的氧化物，它们在XRF光谱中具有良好的响应，并且通常不存在于档案材料中。本研究关注这些氧化物对木质纤维素材料性能的影响。识别标签打印在三种不同类型的纸载体上（Whatman 1号滤纸、符合ISO 9706的纸和亚硫酸盐浆）。在应用标签和人工老化后，对所有样品的颜色变化、平均聚合度、水提取物的pH值和选定的机械性能进行了研究。测量结果表明，所研究的氧化物对纸载体的监测性能没有负面影响，也不会影响其长期老化行为。
