Abstract
An optical disc is plastic and has a printable or ink receptive first layer on which ink printing can take place. It is then coated with a material that covers the printable layer such that when ink jet printing is printed on the outer layer, the ink will pass into and be retained by the ink receptive layer. The outer layer inhibits outward diffusion of the ink when in the presence of moisture so the printer will not be affected by water on the surface of the disc.
