Fluorescent Aggregates of Poly(Cyclohexylene Dimethylene Terephthalate), Method for Obtaining Same, and Use Thereof as a Physically Unclonable Label for Identifying and/or Tracing Packaging for Cosmetic and/or Perfume Products

Abstract

Spherical aggregates of semi-crystalline thermoplastic polyester, poly(cyclohexylene dimethylene terephthalate), with a size distribution of between 160 nm and 200 nm fluorescence in the visible spectrum and are deposited on a thermoplastic aromatic polyester substrate or a thermoplastic polyolefin. The aggregates may be used as a physically unclonable label, for identifying and/or tracing packaging for cosmetic products and/or perfumes. Therefore, the aggregates provide a benefit within the field of anti-counterfeit packaging, particularly in the area of anti-counterfeit packaging for cosmetic and/or perfume products.
