<p>PURPOSE:To obtain a magnetic recording medium, on which a magnetic pattern cannot be visually recognized, with an enhanced production efficiency and improved security properties. CONSTITUTION:In a magnetic recording medium consisting of a substrate, a magnetic pattern layer formed on the substrate, and a color hiding layer for hiding the magnetic pattern layer, the magnetic pattern layer is made of ink containing magnetic powder in a dispersed state and a solvent-soluble, thermoplastic resin, and the color hiding layer is made of ultraviolet- or electron beam- curing, solventless ink containing a pigment or dye.</p> |
