WIPO Patent Application WO/2014/129405
Kind Code:
A1
Abstract:
The present invention is a cooked state indicator material which comprises a polymer composition comprising a polymer and a dye, wherein the polymer composition is prepared by immobilizing the dye in a specific dispersed state in the form of molecules in the polymer, and the dye is an associating fluorescent dye of which the fluorescence wavelength in an excimer state is different from that in a monomer state. Each of the heat-cooked state indicator material for foods and the packaging material is characterized in that the material can non-reversibly change the color phase thereof into a color phase that is different from the initial color phase when the material is stored at a temperature equal to or higher than a specified temperature for a predetermined time period or longer.
