Abstract
A multi-event minimum temperature indicator that includes a substrate, at least two thermochromic compositions positioned on the substrate, and an optional top layer adhered to the substrate. Each thermochromic composition is positioned on a discrete area of the substrate, and the compositions provide a visual indication of exposure to progressively colder temperatures.
