People who are interested in color from nature are increasing. However natural dyes have several defects. They do not have a wide range of color variation. Their colorfastness is not enough. The following results are obtained from this research project aiming to develop the practical use of natural dyes.1. (1) To increase the colors by new method of dyeing, various color dyeing using fresh leaves of Japanese indigo plant was investigated. Conditions to produce a red colorant, indirubin were clarified and the dyeing of chlorophyll was examined. (2) The colors and the fastnesses of ancient madder and Gromwell dyeing were restored with Alum duplicate mordanting.2. (1) The investigation of the effect of detergent components on the colorfastness of laundering to quercetin revealed the contribution sequestering agent to mordant metal ions. (2) To improve color fastness to light, effect of mordant to the colorant of safflower was examined. (3) Improvement of color fastness of various natural dyes by forming lakes was achieved.3. To add new characteristic of natural dyes besides color, antibacterial activity was examined. Sodium copper chlorophyllin was found to have the activity but it disappeared when incorporated in microcapsule. In addition several of 18 commercially available vegetable dyes have the activity.

对大自然的色彩感兴趣的人越来越多。然而，天然染料有几个缺点。它们没有广泛的颜色变化。它们的色牢度不够。本课题旨在开发天然染料的实用性，取得了以下成果. (1)为了增加染色新方法的色彩，研究了靛蓝植物鲜叶的多种色彩染色。澄清了生产红色着色剂靛玉红的条件，并检查了叶绿素的染色。(2)采用明矾复媒法，恢复了古代茜草和格罗姆威尔染色的色泽和牢度. (1)研究了洗涤剂组分对槲皮素染色牢度的影响，揭示了螯合剂对媒染金属离子的贡献。(2)为提高红花染色的耐光牢度，研究了媒染剂对红花染色的影响。(3)研究了色淀形成对各种天然染料染色牢度的改善作用.为了增加天然染料在颜色之外的新特性，对天然染料的抗菌活性进行了研究。叶绿素铜钠盐具有抗氧化活性，但加入微胶囊后活性消失。此外，18种市售植物染料中有几种具有活性。
