It is possible to produce a pigment-modified cyclodextrin film or fiber expected to be versatile in medicines, foods and pesticides such as packing films like wafer (for example, films to wrap food or drugs, and packages whose colors change when contained food begins to leak). It is comprised by p-methyl red of pigment-modified cyclodextrins, each made by modifying alpha-cyclodextrin with p-methyl red, having a structure to be included into different alpha-cyclodextrin of pigment-modified cyclodextrins than the p-methyl red, which leads the pigment-modified cyclodextrins to be highly associated between their molecules to form molecular aggregates.
