A thermal transfer ribbon includes a carrier layer, a release layer, and a thermally transferable ink layer. The ink layer includes an active ink having a chemistry that is configured, responsive to the occurrence of an environmental, physical or biological condition, to undergo a chemical or physical state change causing a change in the color state of the active ink.

Thermal transfer of active ink with dynamic environmental data

A dual-function heat indicator for monitoring two or more modes of heat exposure is described. A manufacturing process for the dual-function heat indicator is also described. Dual-function heat indicators as described may be useful for monitoring the exposure of host products, with which the dual-function heat indicators may be associated, to cumulative ambient heat exposure and to a peak ambient heat exposure, and for other purposes.

Dual-function heat indicator and method of manufacture

A freeze indicator including an indicator dispersion is described herein. Such an indicator dispersion can include: a liquid medium and particles of a colored indicator agent dispersed in the liquid medium. The colored indicator agent particles having an inherent color; wherein the indicator dispersion exhibits the inherent color of the colored indicator agent particles after freezing and is configured to have a less colored appearance before freezing and wherein light scattering masks the inherent color of the colored indicator agent particles before freezing. Some indicator dispersions can be free of color-changing chemical co-reactants. These freeze indicators can be small, have a low cost, and have a simple configuration.

Dual function heat indicator and method of manufacture

Disclosed herein is a temperature condition indicator disposed upon the top surface of a lid or cap for a container or on the container or vial for a perishable product, such as a food or a drug composition. The indicator can change appearance when exposed to a temperature condition, such as a freezing event.

Temperature condition indicators for perishable product containers

Described herein are condition change labels, methods of forming them, and methods of using them. Generally, condition change labels include a first layer including a blister laminated to a first side of a bottom layer thereby creating a container; an indicator substance located in the container; and an adhesive disposed on at least a portion of a second side of the bottom layer, wherein the condition change label has a stiffness less than about 0.06 mN&#x2022;m.

Condition change labels

Described herein are temperature condition indicators (e.g. freezing, threshold temperature, thermal history indicators, etc.) comprising three phase emulsions. Methods of forming and using these indicators, and products that include these indicators, are also disclosed.

Three-phase emulsions used in a temperature condition indicator

A color-changing emulsion for use in a freeze indicator can employ a dispersion medium, for example, an aqueous liquid, a first reactant phase and a second reactant phase, which two reactant phases can both be dispersed in the dispersion medium. The first reactant phase includes a hydrophobic liquid and a first reactant, for example, a color precursor such as a leuco dye. The second reactant phase can include a hydrophobic liquid, and includes, or can be, a second reactant, for example, a color developer such as a leuco dye developer. The first and second reactant phases can be essentially unmixed, and can be co-reactable to provide a color change. In response to a freezing temperature, the color-changing emulsion can coagulate and change color irreversibly. An intense color change can be obtained by using, for example, a suitable leuco dye precursor and developer.

Color-changing emulsions for freeze indicators

Freeze indicators can include an indicator dispersion, a liquid medium, indicator particles dispersed in the liquid medium and a particulate inorganic nucleating agent to inhibit supercooling of the liquid medium. The inorganic nucleating agent can have an ionic surface coating which can help provide a sharp end point. Optionally, freeze indicators can include indicator particles comprising an organic material and a softener to soften the indicator particles and provide the freeze indication with an enhanced visual appearance. Another option is to provide a temperature-sensitive stabilizer to inhibit coagulation of the indicator dispersion at temperatures above the liquid medium frozen state melting point while permitting coagulation of the indicator dispersion at the liquid medium frozen state melting point.
