| The number of colourants and dyestuffs found in nature are enormous. While some of them are fairly well-known, many of them are not commercially important. To provide a comprehensive coverage of all the plants and animals providing colourants and dyestuffs is a very difficult task. This publication attempts to provide only a representative selection of plants and insects yielding colourants and dyestuffs. Its purpose is to give an indication of the wide-ranging sources of natural colourants and dyestuffs and to encourage further research and studies relating to this group of products. [more] |
