초록 ▼

An indicator composition and process capable of changing color in relationship to its exposure to a temperature above and below a base line temperature and to the time of said exposure, for monitoring the time-temperature history of a substrate, depositable as a layer on said substrate, comprising a dispersion of either a binder comprising a reaction inert, neutral finely divided absorbent, in the presence of a reactant comprising a salt of an acid or an organic compound substituted by at least one moiety which, in ionic form, is an anion or a binder/reactant, comprising at least one solid organic polymer whose constituent units contain, as a covalent substituent, at least one moiety which, in ionic form, is an anion; as indicator, at least one acid sensitive pH dye and as activator, at least one base. This composition and process may be utilized to form a solid state device for monitoring integral values of time and temperature during storage of perishables. The device is a single solid indicating layer deposited upon a substrate. The time required for the color change and the activation energy of the device can be varied by varying the concentration and nature of reactants, catalysts, additives and polymeric binder/reactant matrix. The color change can be gradual or abrupt and exhibited as a continuous strip, as alphanumeric symbol(s) or as a line array which can be read by a bar code reader.

대표청구항 ▼

A method of determining the elapsed shelf life of a perishable product comprising the steps of (1) packaging said product with an indicator device capable of changing color in relationship to its exposure to a temperature above and below a base line temperature and to the time of said exposure, for monitoring the time-temperature history of a substrate, comprising a solid state dispersion comprised of: (a)(i) a binder comprising a reaction inert, neutral finely divided absorbent, in the presence of a reactant being a salt of an acid or an organic compound substituted by at least one labile moiety which, in ionic form, is an anion or (ii) a binder/reactant, comprising at least one solid organic polymer whose constituent units contain, as a covalent substituent, at least one labile moiety which, in ionic form, is an anion; (b) as indicator, at least one acid sensitive pH dye which is non-phototropic during the time of said exposure, (c) as activator, at least one base, deposited as a layer on said substrate; and (2) observing the color change of the device after storage.
