Resumen de: GB2633332A

An article comprises a three-dimensional surface covered with a functional layer comprising an optically-readable PUF (physical unclonable function), whereby, in use, reading the PUF from multiple perspectives allows the article to be authenticated with different identities from the different perspectives. Typically, the surface has a plurality of faces. The article may be a machine part, clothing, footwear, bag, food, artwork, electronic component, certificate, ID card, gemstone, medicine, tax stamp, currency, packaging, or labelling. The layer may be edible. Typically, the PUF comprises a fluorescent compound, e.g. a rhodamine dye, cyanine dye, phthalocyanine dye, porphyrin dye, or a quinacridone. Preferably, the layer is formed by applying a PUF coating composition, e.g. an ink, to the surface. The PUF coating composition may be prepared by adding an optically-readable material, e.g. a rhodamine dye, to a coating composition, e.g. a UV-curable lacquer. A method of making the article is also disclosed.

Resumen de: US2025059385A1

A dual-modal information storage and anti-counterfeiting material, and its preparation method are provided. The dual-modal information storage and anti-counterfeiting material uses cadmium sulfide quantum dots (CdS QDs) as information storage material, and uses the controllable photocorrosion of CdS QDs to achieve dual-modal optical information storage and anti-counterfeiting applications. Firstly, the type of ligands and modification degree of CdS QDs are precisely controlled during the aqueous phase synthesise process, so as to effectively control the photocorrosion phenomenon under UV light irradiation. Subsequently, the CdS QDs are loaded in the hydrogel network, and they are also loaded on the substrates such as cloth and paper by spray coating, dip coating or 3D printing, and the information is stored by digital light patterning. Different from the photochromic function of traditional anti-counterfeiting material, the CdS QDs shows dual-modal patterning characteristics in a wide wavelength range.
