Abstract (en)
[origin: WO2014090839A1] The present invention concerns a method for checking the authenticity of a security document, in particularly a fiduciary document, which comprises an area with, within or at the surface of this area, a reversible mecanoluminescent compound of formula (i): In which R represents an alkyl chain comprising 1 to 12 carbon atoms, which comprises a step in which said area is subjected to ultraviolet radiation such that the whole of said area is visible to the naked eye in a first fluorescent colour (C1), characterised by the fact that it also comprises a step that consists of heating at least said area to a temperature of at least 50° C, without subjecting it to any friction or mechanical stress whatsoever, the revealing of the authenticity of said document being confirmed by the shift from said first colour (C1) to a second fluorescent colour (C2) different from the first.
