<p>An identification device (2) for marking an article, the identification device having a low emmissivity at thermal infrared wavelengths and comprising a plurality of layers including a first layer (14) arranged to be substantially transmissive at thermal infrared wavelengths and substantially absorbing at at least one visible wavelength so as to impart a visible colouration thereto, and a second layer (12) arranged as a specular reflector at thermal infrared wavelengths. A method for marking article, in particular a vehicle with said identification device (2). The first layer (14) may comprise a plurality of polychromatic dyes and the second layer (12) may comprise a metallic reflector selected from at least one of aluminium, chromium, nickel, gold, copper, silver and titanium.</p> |
