无碳复写纸档案字迹材料耐久性与环境温湿度、酸碱性物质、有机溶剂、微胶囊牢度、显色剂性能等保存环境和内在因素密切相关。本文就影响无碳复写纸档案字迹材料耐久性的温湿度、酸碱、有机溶剂、微胶囊牢度、显色剂性能等因素进行研究和分析。 Durability of carbonless copy paper handwriting materials and environmental temperature and humidity, acid and alkali substances, organic solvents, microcapsules fastness, developer properties and other preservation of the environment and internal factors are closely related. In this paper, the temperature and humidity, acid and alkali, organic solvents, microcapsule fastness, developer property and other factors that affect the durability of non-carbon copy paper handwriting materials were studied and analyzed.
