RECORDING MEDIUM FOR SECURITY

摘要

Disclosed is a recording medium for security, comprising: a detection base layer containing a material for detection and having a printable base integrated with the material for detection; and a shielding layer formed on both sides of the detection base layer so as to shield the material for detection. Here, the material for detection can be a soft magnetic material having a residual magnetic flux density of 0.1T or more, a coercive force of 1 to 50A/m and a magnetic permeability of 500 to 100,000H/m, when the frequency is 10kHz.
