<p><P>PROBLEM TO BE SOLVED: To provide a patch transfer medium which can easily transfer a patch to a transfer object and has a fluorescence emitting hologram excellent in heat resistance and light resistance in addition to abrasion resistance and solvent resistance for protecting the surface of the medium even when used repeatedly many times and a forgery preventing medium using it. <P>SOLUTION: The patch transfer medium comprises a transfer material 10 (1) composed of a transparent substrate 11 and a hologram layer 15 containing a fluorescence emitting rare earth complex, a reflection layer 17, and an adhesive layer 19 on one side of the substrate 11 and a support material 30 (2) in which a peelable resin layer 33 is attached to a support substrate 31. The transfer part of the transfer material 10 is subjected to half-cut treatment to make the patch 21, and the patch 21 is laminated peelably on the peelable resin layer 33 surface of the support material 30. The hologram layer 15 contains an ionizing radiation curing resin and the fluorescence emitting rare earth complex, and the absorption wavelength range of the ionizing radiation curing resin is different from the absorption wavelength range of the fluorescence emitting rare earth complex. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
