The present invention is generally in the field of measuring and indicating techniques and relates to a time-temperature indicator and methods of manufacturing and use thereof. More specifically, the time-temperature indicator comprises a time temperature indicator comprising at least one metal layer or metal containing layer and in direct contact to the metal layer or to the metal containing layer at least one doped polymer layer, wherein the dopant is an acid, a base or a salt or a photolatent acid or a photolatent base which dopant is added to the polymer, and/or at least one polymer layer wherein a polymer is functionalized with acidic or latent acidic or basic or latent basic groups; or a time temperature indicator comprising at least one polymer layer containing metal particles and a photolatent acid or a photolatent base, or at least one polymer layer containing metal particles wherein the polymer is functionalized with latent acidic or latent basic groups.

Time temperature indicator

The present invention is generally in the field of measuring and indicating techniques and relates to a time-temperature indicator and methods of manufacturing and use thereof. More specifically, the time-temperature indicator comprises at least one metal layer or metal containing layer, and in direct contact to the metal layer or to the metal containing layer at least one pad member affixed onto a pad carrier layer, wherein the pad member comprises a pad made of an absorbent material and a dopant medium, whereby the dopant medium comprises a liquid medium or a viscous medium or a viscoelastic medium which is doped with a dopant that destroys the metal/metal containing layers such as an acid, a base or a salt or a photolatent acid or a photolatent base.
