In order to conserve color on various cultural properties, examination and recording of deterioration of color are performed and developed as well as fixing and re-adhering treatment for the color.(1)X-ray deffraction method was employed for identifying the pigments which were used by a painter for national important wooden building, and found that two different pigments are used with one name depending on the works.(2)Raking light apparatus was developed and a first model for practical use was made up. The apparatus projects parallel light beam with fixed angle and even light value at any point of a flat object, and gives ideal lighting condition for taking photo of recording damaged color layer.(3) Red lead color on wood was examined after artificial aging by weathering chamber, to know the minimum concentration of animal glue in which the red lead color started peeling after the aging. It was confirmed that color layer which was prepared with acrylic resin as a medium, showed good durability in its high concentration.(4)Degree of discoloration was measured on three pigments on wood which were traditionally used by painters for wooden building.(5)The ratio of hydroxy-proline to other amino-acid contained in three kinds of animal glue, was found to indicate the source of the glue.(6)The condition of color on wooden member of shrines and temples were surveyed. Paintings on paper of sliding door and a wooden ornament were examined for remained color layers.

为了保存各种文化财产的色彩，对色彩劣化进行检查和记录，进行显影，并对色彩进行固着和再附着处理。(1)采用X射线衍射法来鉴定国家重要木结构建筑画家使用的颜料，发现根据作品的不同，使用了两种不同的颜料同一个名称。(2)开发了耙光装置，并制作了第一个实用模型 向上。该装置将固定角度、光值均匀的平行光束投射到平面物体上的任意一点，为拍摄记录受损色层提供了理想的照明条件。(3)通过风化室对木材上的红铅色进行人工老化后的检测，以了解老化后红铅色开始剥落的动物胶的最低浓度。经证实，以丙烯酸树脂为介质制备的彩色层在高浓度下表现出良好的耐久性。(4)测量了传统上木建筑油漆工使用的三种颜料在木材上的变色程度。(5)发现了三种动物胶中所含的羟基脯氨酸与其他氨基酸的比例，以指示胶的来源。(6)木构件上的颜色情况 对神社和寺庙进行了调查。检查滑动门和木制装饰品的纸上绘画是否有残留的颜色层。
