Beschreibung
Zusammenfassung:	Co-topo-polymeric indicator compositions and methods for making and using the same are provided. Indicator compositions of the invention include a polymer and undergo a color change, which may be reversible or irreversible, in response to an applied stimulus, e.g., temperature. Aspects of methods of producing the compositions include setting a fluid co-topo-polymeric precursor composition into a solid product and then subjecting the solid product (either immediately or after a delay period) to polymerizing conditions to produce the desired indicator composition. Also provided are indicator devices that include the indicator compositions of the invention. The compositions of the invention find use in a variety of different applications.
