<p>PROBLEM TO BE SOLVED: To solve such problems as an easy tendency to peeling of a base material sheet and release layer of a sheet for attachment and a difficulty in peeling on the contrary, and as the influence of irradiation with UV rays information, in the case of a transfer layer including a optical diffraction structure or an excessive incresase in the adhesive strength between the base material sheet and the release layer by the heat during lamination of a light reflective layer. SOLUTION: The release layer 3 and the transfer layer 4 are successively formed on the under surface of the base material sheet 2 and a stabilizer is preferably incorporated into the release layer 3. The thickness of the release layer 3 is preferably specified to >=1.5μm and the transfer layer 4 is formed of a laminated structure composed, successively from the release layer 3 side, of an optical diffraction structure forming layer 5, a light reflective layer 6, a thermosensitive adhesive layer 7, etc., and after the thermosensitive adhesive layer 7 side is attached to an adherend, the base material sheet 2 is stripped, by which the transfer of the optical diffraction structure, etc., can be formed without a hitch. The transfer layer 4 may be internally accompanied with an intermediate layer 8 or/and a primer layer 9.</p> |
