摘要:
A protective, switchable layer adapted for use in transient imageable documents is disclosed. The protective layer can be disposed on an underlying photochromic layer and enables writing or imaging the underlying layer. The protective layer prevents unintentional writing on the photochromic layer, such as can otherwise occur from exposure to certain wavelengths of light.
