유화 작품 색맞춤용 재료 특성 연구 Ⅱ: 복원용 물감을 중심으로 = A Study on the Retouching Materials for Oil Paintings : Using Restoration Colors

다국어 초록 (Multilingual Abstract)

In this study, the Restoration color of three manufacturers (Companies A, B, and C) usedfor retouching are selected, and the differences in paint properties based on the resin type used byeach manufacturer as the medium are compared. The results indicate that the paint produced by eachmanufacturer differs in terms of the ingredients, color development characteristics, durability, andreversibility. The paint by Company A (binder: mastic resin) shows the best reversibility; however,it exhibits significant discoloration and numerous cracks after deterioration, as well as chalking in somecolors. The paint by Company B (binder: acrylic resin) is superior to those of other manufacturersin terms of discoloration and cracking, although its reversibility is unsatisfactory. The paint byCompany C (binder: aldehyde resin) shows significant discoloration, and small holes are observed onthe sample surface after deterioration. The results are consistent with the deterioration characteristicsof the resin used as the medium; additionally, the restoration color differs in terms of durability andreversibility depending on the resin used as the medium. It is expected that the above results canbe used not only as essential reference data when selecting materials for retouching, but also to predictproblems that may appear in the restoration part of the work using Restoration color and to comeup with management measures.

국문 초록 (Abstract)

본 연구에서는 국내외에서 유화 작품의 색맞춤에 활발히 사용되고 있는 복원용 물감(A사, B사, C사)을 대상으로 성분 분석, 내구성, 가역성 평가를 진행하여 제조사별 물감의 특성을비교하였다. 연구 결과 동일한 색명의 물감일지라도 제조사별 미디엄으로 사용된 수지의 성분,내구성, 가역성 차이가 존재했다. 유향수지를 기반으로 하는 A사의 물감은 가역성이 가장 우수했으나 열화 후 변색과 균열이 많이 발생하였으며 일부 색상에서는 분말화 현상이 관찰되었다.
아크릴수지를 기반으로 하는 B사의 물감은 변색, 균열에 있어서는 다른 제조사에 비해 안정적이었으나 가역성이 떨어졌다. urea-aldehyde 계열의 수지를 기반으로 제작된 C사의 물감은 변색이 많이 발생했고 열화 후 시료 표면에서 작은 구멍이 관찰되었다. 제조사별 물감의 열화 특성은 성분 분석을 통해 규명된 미디엄으로 사용된 수지의 열화 특성과도 일치하였으며 복원용물감의 제조사별 특성차이는 미디엄으로 사용된 수지의 차이에서 기인한다는 것을 확인하였다. 본 연구 결과는 색맞춤용 재료 선정 시 참고자료로 활용될 수 있을 뿐 아니라 복원용 물감으로 색맞춤한 작품에서 나타날 수 있는 문제점을 예측하고 관리 방안을 마련하는 데에도 활용될것으로 기대된다.
