摘要:
A recording medium having a reflective layer (6) on a transparent support (1) can be obtained by physical development of a layer of physical development nuclei (2) in the presence of metal ions. The ions can for instance migrate from a colloid layer of a metal salt (6). The association of developed nuclei, after physical development, results in a reflective layer with metal atoms obtained by reducing the metal ions, whose reflectivity is reduced on irradiation through the transparent support. The manufacture of such recording media does not require vacuum system.
