Composition comprising at least one first fluorophore, which has a first quenching temperature ranging from 0°C to 200°C, and at least one second fluorophore, which has a second quenching temperature ranging from 0°C to 200°C and that differs from the first quenching temperature by at least 5°C and emits light radiation at least at a distance of 5nm from the peak of emission of the first fluorophore; the particular trend of the colour variation of the composition irradiated by means of UV radiations as a function of the temperature is used to verify the authenticity of an object on which the composition has been applied. |
