GALVANIC-CORROSION PREVENTIVE LABEL

PROBLEM TO BE SOLVED: To provide a galvanic-corrosion preventive label for preventing galvanic corrosion on a thin metallic layer, even when used in a high-temperature and humid environment, or when stuck to an electroconductive adherend such as a metal. SOLUTION: The galvanic-corrosion preventive label 10 comprises a PET layer 11, a hologram layer 12, a vapor-deposited layer 13, an underlayer 14 for the vapor-deposited layer, an adhesive layer 15 and a strippable paper 16, which are layered in this order. The PET layer 11 protects the hologram layer 12 from being damaged by external force and gives the hologram layer 12 strength: the hologram layer 12 has a reproducible two-dimensional or three-dimensional image by white light, which is recorded in the layer as a hologram image: the vapor deposited layer 13 is made of aluminum for securing the hologram performance of the hologram layer 12: the underlayer 14 for the vapor-deposited layer 14 is a non-conductive resin or film for preventing a current from passing through between the adherend and the vapor-deposited layer 13: the adhesive layer 15 sticks the galvanic-corrosion preventive label 10 on the surface of the adherend: and the strippable paper 16 is a sheet for protecting the adhesive layer 15 until the time of use.
