Abstract (en)
[origin: WO2012010807A2] The invention relates to a treatment for printing a surface with an ink that comprises a compound that exhibits a change of electronic spin state as a function of temperature, imparting optical properties such that the ink is visible in a temperature range that includes an ambient temperature of around 20°C and is transparent in the visible spectrum when the ink is brought to a temperature above said range and then brought back down to a temperature within the range.
