Patent number: 4726858Abstract: A recording material made of an alloy capable of exhibiting different spectral reflectances at an equal temperature, depending on a heating-cooling cycle to which the alloy is subjected. The alloy can possess in solid state different crystal structures at a first temperature higher than the room temperature and at a second temperature lower than the first temperature but not lower than the room temperature. A part of the surface of the alloy exhibits, as a result of being quenched from the first temperature, a crystal structure which is different from the crystal structure at the second temperature, while the other part possesses the crystal structure at the second temperature, so that these two parts exhibit different spectral reflectances.
