黏著劑是檔案整理作為中經常使用的固著材料，然而，在檔案整理及裝訂的過程若使用不當的黏著劑，在保存過程中，就很容易致使紙張產生黃化、硬化、脆化，甚至是不可預期的劣化情況，進而直接或間接影響、威脅到紙張的長期保存狀態。國家檔案主要來自於各機關執行公務所留存、具有永久保存價值的公務紀錄，隨著時代不同、選用概念演變、資源取材等不同考量，各機關對於加附在檔案上所使用的黏著劑不一而足，其中，動物膠也是機關經常使用的一種黏著材料。動物膠保存不易，使用時操作難度較高，使用後揭除也相對困難，一旦劣化後對檔案原件的保存更是存在極大威脅。本研究從文獻回顧、抽樣調查、黏著劑移除測試等3方面著手，藉由調查國家檔案受黏著劑劣化影響之情形，掌握各種黏著劑劣化的狀態及數量比率，並選定動物膠為深入探討項目，試圖尋找較適切的修護或處置方式，梳理出一些關於動物膠使用及移除問題，以增進檔案保存修護之專業知能，同時提升紙質類國家檔案永續典藏之可能性，降低檔案無法復原之風險。

If improper adhesives had been used in handling archives, paper materials may gradually turn yellowish, hardened or fragile, leading to unexpected deterioration in the process of preservation. This would directly or indirectly hamper the long-term preservation of the paper archives. This research includes three areas of discussion: documentary review, sample survey, and removal tests. Through realizing the conditions of deteriorated adhesives in national archives, the authors intend to shed light on the conditions, quantities and ratios of the different adhesives used. Meanwhile, animal glues are chosen for conducting in-depth research in order to find out better means of archive repair or handling. We hope to identify proper ways of using or removing animal glues. In sum, our goal is to help enhance the professional expertise and capability of the National Archives Administration in preservation and repair, increase the chance of preserving paper archives, and reduce the risks of failing to recover damaged archives.
