<p><P>PROBLEM TO BE SOLVED: To offer a forgery preventive magnetic tape transfer sheet which is excellent in heat resisting nature and suffers little whitening of optical film by the high-temperature card manufacturing process. <P>SOLUTION: The forgery preventive magnetic tape transfer sheet and the card transferred using the forgery preventive magnetic tape transfer sheet have a transfer layer prepared on the sheet type support and, when to be transferred, it exfoliates from the support and is transferred to the body to be transferred, and the transfer layer has at least, in the order from the closer side of the support, (α) transparent diffraction structure cambium which has minute concave-convex surfaces for generating diffracted light (β) diffraction effect stratum which consists of optical film prepared closely adhering to the concave and convex surfaces and reflects light permeated thorough this diffraction structure cambium (γ) heat-resistant stratum prepared to coat this diffraction effect stratum (δ) magnetic recording stratum prepared to coat the heat-resistant stratum and (ε) the adhesive stratum prepared to coat the magnetic recording stratum. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
