Abstract
Disclosed embodiments may relate to a time-dependent color-changing label for a product. The label may include a first layer comprising a plurality of particles, the particles comprising a time dependent color-changing material that changes color after a predetermined time period, the predetermined time period being greater than one month. The label may also include an attachment structure attaching the first layer to the product. In certain embodiments, the first layer may include a polymer, and the particles may include glass microspheres containing the time-dependent color changing material. The particles may be embedded in the polymer.

A time-dependent color-changing label for a product, comprising:
- a first layer comprising a plurality of particles embedded in a polymer, the plurality of particles comprising a time-dependent color-changing material that changes color after a predetermined time period, the predetermined time period being greater than one month, and wherein each particle comprises an encapsulation device having a porosity that corresponds to the predetermined time period after which the color change occurs;
- a second layer at least partially covering the first layer, wherein the second layer comprises a plurality of perforations configured to expose the first layer to ambient atmosphere;
- and
- an attachment structure configured to attach the first layer to the product.
A printable sheet of time-dependent color-changing labels, comprising:
- a substrate;
- and
- a plurality of time-dependent color-changing labels comprising:
- a first layer comprising a polymer and a plurality of particles embedded in the polymer, the particles comprising a time-dependent color-changing chemical, and wherein each particle comprises an encapsulation device having a porosity that corresponds to the predetermined time period after which the color change occurs;
- a second layer at least partially covering the first layer, wherein the second layer comprises a plurality of perforations configured to expose the first layer to ambient atmosphere;
- and
- an adhesive layer releasably securing the labels to the substrate.
A time-dependent color-changing label, comprising:
- a first layer comprising a plurality of particles embedded in a polymer, the particles comprising a time-dependent color-changing material that changes color after a predetermined time period, and wherein each particle comprises an encapsulation device having a porosity that corresponds to the predetermined time period after which the color change occurs;
- a transparent second layer encapsulating the first layer, wherein the second layer comprises a plurality of perforations configured to expose the first layer to ambient atmosphere.
