Beschreibung
Zusammenfassung:	A printable ink for reversible thermal indicators that includes microcapsules retaining therein a core material that is opaque as a solid and transparent as a liquid, and a binder and a rheology modifier as a carrier for the microcapsules. The binder and the rheology modifier are either the same substance or different substances. The microcapsules in the printable ink retain the core material therein for repeated, reversible transitions from solid to liquid and liquid to solid.
