Solution Overview

Problem

Conventional printing techniques face challenges when trying to print encapsulated materials due to issues with binders and formulating agents, which can negatively impact the shell material and the functionality of the encapsulated indicator materials.

Innovation Solution

The use of a gelled material as an ink composition, which includes a gelling agent, a carrier liquid, and microcapsules encapsulating environmental indicator materials, allows for the creation of a printable ink that maintains the integrity of the microcapsules during printing and activation.

AI summary

Disclosed is a media element, comprising a media substrate, a gelled material adhered to the media substrate, and a plurality of microcapsules suspended in the gelled material. Each microcapsule encapsulating an environmental indicator material in a non-activated configuration and releasing the environmental indicator material when ruptured, the environmental indicator material configured, in response to exposure to a predetermined environmental condition, to change from an initial state to a second state producing an observable effect. The plurality of microcapsules prevent an occurrence of the observable effect while in the non-activated configuration and allow the occurrence of the observable effect when the environmental indicator material is exposed to the predetermined environmental condition after at least a portion of the plurality of microcapsules are ruptured.
