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.
A device for activating and dispensing a two-label system in which the system becomes activated upon contact of a first label with a second label, the device comprising a first dispenser carrying the first label and a second dispenser carrying the second label, said first and second dispensers being disposed such that said first dispenser dispenses the first label and said second dispenser dispenses the second label, such that the two labels become attached to one another to thereby activate the two label system, and the attached activated layers are thereby provided, wherein said first and second dispensers are disposed such that said first dispenser dispenses and attaches said first label onto a surface of said second label being carried by said second dispenser, and then said second dispenser dispenses a combined label.
