Abstract (en)
[origin: WO2018036652A1] The invention relates to a security element for enhancing the security of documents of value, comprising a first polymer, which contains a feature substance and is at least partially surrounded by a second polymer, wherein the first polymer is a hydrophobic, water-insoluble polymer, which can be converted into a hydrophilic, water-soluble polymer if the pH is increased and the ambient temperature is increased for a treatment period of less than 60 minutes, preferably less than 30 minutes, and the second polymer is a hydrophilic, water-soluble polymer, wherein the increased pH is greater than 12, preferably greater than 10, and the increased ambient temperature is greater than 90°C, preferably greater than 60°C.
