초 록
전문적인 보존시설이 없는 대부분의 도서관에서는 손상된 도서의 간단한 수선 처리 및 응급조치 시 일반시판용 합성수지 접착제를 사용하고 있고, 이는 크게 PVAc 계열(Pa), 아크릴 계열(Ac)과 PVP 계열(Pv)로 나눠진다. 국립중앙도서관 자료보존실에서 사용하고 있는 보존용 합성수지 접착제(Pa-1)와 일반시판용 합성수지 접착제 중 대표적인 접착제를 골라 열화특성을 연구하기 위해 인공열화를 진행한 뒤, 약 한 달 동안 산성도(pH)와 색도를 측정하였다. 산성도 실험 결과에서 Pa-1(pH 7~7.5)과 Ac-2(pH 6.5~8)는 보존처리에 적합한 범위를 나타내었다. 색도실험에서 황변도를 나타내는 △b*는 Pa-1

ABSTRACT
Most of the libraries and archives that lacks conservation lab facilities, frequently apply common synthetic resin adhesives such as PVAc group(Pa), acrylic group(Ac) and PVP group(Pv) on simple repairs. The archival quality synthetic adhesive(Pa-1) that is used at the National Library of Korea and the common synthetic resin adhesives were selected for the experiments. Accelerated aging test was applied on the adhesive samples and change of the pH and chromaticity were measured for one month. As the result of the pH mesurments, Pa-1 and Ac-2 were at the acceptable pH range. As the result of the chromaticity mesurments, degree of yellowing(△b*) showed smaller change to greater change in the following order; Pa-1
