Particles with photochromic and light absorbing material for reimageable medium

摘要

Various embodiments provide a plurality of particles and a reimageable medium including the plurality of particles. The plurality of particles can include a binder; a photochromic material; and a light absorbing material. The photochromic material is capable of reversibly converting among a less colored form and a more colored form in response to a predetermined wavelength scope, where light absorption by the light absorbing material is less than about 50% of light absorption by the less colored form of the photochromic material.
