    • Encrypted markers that are not readily detectable can be revealed by treatment with a specific reagent used as a developer to reveal a readily detectable physical property of the marker, such as a characteristic fluorescence emission after excitation with a particular excitation wavelength, or to reveal a visible color. The encrypted marker can be developed in situ, or a sample can be removed by brushing, scraping, swabbing or scratching the marked object or item and developing the encrypted marker or a sample thereof with the appropriate developer to reveal an overt marker or optical signal. The marker can be revealed by exposure of the encrypted marker or a sample thereof to the developer in any suitable form, such as a solution, a slurry, a swab, a solid (such as in granular form), or a gas or a vapor that includes a developer.

    • This invention relates to the field of authentication of coating compositions such as varnishes, inks and paints, and it is particularly useful in the field of authentication of such coating compositions when applied to substrates like banknotes or other valuable documents. It is particularly directed to a marked coating composition. e.g. an ink, that is marked with a marker (taggant) such as to allow for its authentication, and a method for authenticating such a marked coating composition. The marking is achieved by covalently binding a taggant to a coating composition component. e.g. such used for security documents. The taggant, which is not extractable through usual chemical treatments like washing methods or the use of solvents, can be detected and identified upon thermally induced chemical fragmentation with a PY-GC-MS apparatus. The marked ink or the marked substrate is thus authenticated as belonging to a particularly marked ink, varnish or batch.
    • 本发明涉及涂料组合物如清漆,油墨和油漆的认证领域,并且当在涂布到诸如纸币或其他有价值的文件的基材上时,这种涂料组合物的认证领域特别有用。 特别涉及一种显着的涂料组合物。 例如 用标记(标记剂)标记的油墨,以允许其认证,以及用于认证这种标记的涂料组合物的方法。 标记通过将标签剂与涂料组合物组分共价结合来实现。 例如 如用于安全文件。 通过使用PY-GC-MS装置的热诱导化学碎裂可以检测和鉴定标签牌,其通过通常的化学处理如洗涤方法或溶剂的使用不能提取。 标记的油墨或标记的基材因此被认证为属于特别标记的油墨,清漆或批料。
