PURPOSE: To make a display permanently visible when a surface material is separated from a releasing agent coating film, even though the display is invisible up to that time and to prevent from pasting again without leaving a warning message, which ordinary persons will not fail to notice, even after the surface material has been carefully peeled. CONSTITUTION: The labelling material 10 is constituted, so as to contain the releasing agent coating film 12 and a transparent flexible polyester film 11, on which words are printed in an invisible repeating pattern form, to cover the print with a transparent primer coating film 14 and to cover the primer coating film with a vapor-deposited metallic film 16. A pressure-sensitive adhesive layer 18 on a removal liner 20 is laminated on the metal. And when the labelling material 10 is stuck to a base body 22 with the pressure-sensitive adhesive layer 18 after the liner 20 has been removed and the surface material 11 has been released from the base body 22, the labelling material 10 is broken at the weakest part, that is between the releasing agent coating film 12 and the surface material 11. As a result, the invisible words on the releasing agent coating film are made visible by the part of the metallic layer 16 remaining on the base body 22. |
