Abstract
Abstract A recording medium is provided which comprises a recording layer comprising at least one set of image-forming units containing a region holding a photosensitive protein and a color-developing means capable of developing a color according to a change in the hydrogen ion concentration in the region. Each of said image-forming units within the same set having a photosensitive protein sensitive to a different wavelength.
