METHOD OF AUTHENTICATING POLYMERS, AUTHENTICATABLE POLYMERS and AUTHENTICATABLE ARTICLES.

It is the method of attesting that examination polymer is polymer which can be attested with 1 enforcement form, While the polymer which can be attested contains substrate polymer and a thermochromism compound and a thermochromism compound has the first signal on the first temperature and attestation wavelength, Have the second signal on attestation temperature and an attestation wavelength, and the first signal and second signal differ from each other, Attestation temperature is a temperature higher than the first temperature, and examination polymer is exposed to sufficient stimulus for the method concerned to raise a part of examination polymer to attestation temperature, and produce a heating section, The test signal of the heating section of examination polymer is measured on an attestation wavelength, and if the test signal is the same as the authentication signal of the polymer which can be attested, a method including attesting with examination polymer being polymer which can be attested will be indicated.
