明治から昭和にかけて活躍した日本画家上村松園の技法と表現について、作品の科学的な分析と下絵および自叙伝の調査からその特徴を明らかにすることを目的とした。本画2作品を蛍光X線回折、赤外線撮影、顕微鏡撮影を通じて分析したところ、日本画で古くからある顔料と、明治以降新しく使われ出した顔料がともに検出された。また文献資料にある記述と異なり、絹の表からのみ彩色されていることが解った。表現においては同一画面のなかでも人体とそれ以外で技法に意図的な差異があった。作家の原点である縮図帖の分析では、色とモチーフの分類および電子書籍化を実施した。

The Filmon endless sound-belt,the subject of this report,is a celluloid sound recording media manufactured in 1937 by Nihon Filmon Co.,Ltd.at what is now Komae-shi,Tokyo. The sound belt was developed in Japan to overcome the short recording time possible on SP records,which at that time was the mainstream recording media in the world. It is an extremely short-lived recording media that disappeared in about 3 years with the development of magnetic tapes for recording. Although short-lived, the sound belt made long recordings at one stretch possible,which could not be done with SP records. Thus,valuable recording of kiyomoto, nagauta and other types of Japanese music have remained. The Department of Intangible Cultural Heritage of the National Research Institute for Cultural Properties, Tokyo and The Tsubouchi Memorial Theatre Museum Waseda University have embarked on a joint study and digitization of the Filmon endless soundbelts in collections of the Institute, the Museum and other museums as well as in private collections. This report discusses the method that has made it possible to restore and to re-listen to deteriorated (hardened, deformed) or severed Filmon endless sound-belts.

In the previous issue of this bulletin (Science for Conservartion 51, published in 2011), a report was made on a method for restoring deteriorated (hardened or deformed)Filmon Endless Sound-Belt. The previous method employed the typical characteristic of celluloid, that celluloid is a heat-reversible material. In other words,it starts to soften when temperature exceeds 65℃ and becomes completely soft when temperature exceeds 85℃ and reaches 100℃, but regains its hardness and resilience when cooled. However, there were several problems with this method. For instance, there was a risk that the unwound tape would become damaged in the process of rewinding it and that applying too much heat would damage the sound grooves. This year the previous method was revised to solve these problems and soften the sound-belt so that it can be replayed.
