<p>PURPOSE:To effectively prevent electrification of the surface of a print receiving layer by forming a conductive printing design on the side provided with the layer. CONSTITUTION:A conductive print pattern is formed on the side provided with a print receiving layer on a base to reduce the electric resistance of the surface of the layer, thereby suppressing charging. The print design is formed by dispersively mixing conductive powder together with binder resin, dye, organic solvent and other necessary components to prepare conductive printing paint, and printing the paint in various designs on the layer or the base under the layer. The powder to be used includes powder formed by coating the surface of titanium oxide with in oxide, etc., carbon black, graphite, silver powder, Ni powder, Ni-coating mica, etc. Thus, when amount, number of times, date, etc., are printed to be sold, it can prevent inconvenience of selling two magnetic cards simultaneously due to attractive adherence of the cards caused by the charge of static electricity on the surface of the layer.</p> |
