The problem addressed by the invention is that of preventing the manipulation of an electrical circuit (250) in a valuable product or security product (100), wherein the electrical circuit (250) is formed by at least one circuit element (210) and at least one conducting track (220) electrically connected to the at least one circuit element (210). This problem is solved in that the valuable product or security product (100) contains core/shell particles (300) containing at least one first chemical substance (400), wherein the core/shell particles (300) are formed by a shell (310) and by a core (320) surrounded by the shell (310), such that the at least one first chemical substance (400) can be released by means of an action on the valuable product or security product (100), can reach the at least one electrical circuit (250), and, there, can at least impair the electrical functional capability of the electrical circuit alone or after reaction with at least one second chemical substance (500). |
