Outline of Final Research Achievements

This research project examined the surficial or aspect analysis method using infra-red images to identify coloring material on paintings. In order to evaluate the effectiveness of the method, we selected "the illustrated book on natural history" owned by the Takamatsu Matsudaira family for the analysis. In addition, it was found that there is a difference in how pigment and dye appears on an infra-red image. Therefore, the infra-red image can be effectively used to distinguish the two from each other. We obtained sufficient standard data of pigments and dyes that can be used to determine the coloring materials.

Academic Significance and Societal Importance of the Research Achievements

これまで一般に行われてきた赤外線画像を墨線などの検出に活用するのではなく、彩色材料の面的調査への適応を検証した。赤外線画像は①非破壊で簡単に有益な情報が得られる、②面的な調査が可能となる、③面的な情報を得ることで次に行う元素分析などの点分析に役立てられるという利点がある。本研究により赤外線画像の活用は彩色材料の面的調査に有効であることが確認でき、今まで点でしかなかった情報を面の情報へと広げることができるようになった。
