项目摘要

The effects of Cu-containing pigments on degradation of Japanese paper have been investigated. In the first place, a hand- coloured wood- block print of the late Edo era is observed. To clarify the degradation mechanism, sheets of modern Japanese paper painted with powdered malachite are aged in an environment of 80℃, 65%RH. As a result, the Cu species diffuse from the right to the wrong side of the paper. In the second place, the effects of chelating agents on the degradation of Japanese paper (lining paper) have been investigated. The lining kozo paper treated with chelating agents (Ethylene diamine tetraacetic acid : EDTA, Diethylene triamine pentaacetic acid : DTPA or Hydroxyethylidene diphosphonic acid : HEDP) and / or calcium carbonate (CaCO3) was pasted to the painting gampi paper coated with powdered malachite. Specimens were aged in a forced air circulation oven at 80℃ and 65%rh. The lining kozo paper treated with EDTA together with CaCO3 were effective in reducing the acidification, discolouration and depolymerization by Cu ions. The effect of DTPA was better than the others.

研究了含铜颜料对日本纸降解的影响。首先，观察到江户时代晚期的手工彩色木刻版画。为了阐明降解机理，将涂有孔雀石粉的现代日本纸张在80℃、65%RH的环境中老化。结果，铜物种从纸的右侧扩散到纸张的反面。其次，考察了螯合剂对日本纸(衬纸)降解的影响。将经螯合剂(乙二胺四乙酸：EDTA、二乙三胺五乙酸：DTPA或羟乙叉二膦酸：HEDP)和/或碳酸钙(CaCO3)处理过的衬纸粘贴到涂有孔雀石粉的金平彩绘纸上。样品在80℃、65%Rh的强制空气循环烤箱中老化。用EDTA和CaCO3复合处理的衬纸能有效地减少铜离子的酸化、变色和解聚。DTPA的效果优于其他两种方法。
