(57) [Summary] [Purpose] No overcoat is required, and a barcode can be attached by a thermal transfer method to allow issuance on a case-by-case basis. It retains the initial shape without occurring, and it is difficult for ink to transfer to the mold, resulting in mold contamination and poor tire appearance, To obtain a bar code label for a rubber tire that keeps the applied bar code clear and firmly adheres to the formed tire through the vulcanization process. [Structure] A plastic film (2) containing a white filler and having a melting point of 200 ° C. or higher has a heat transfer barcode (1) made of a resin-based ink exposed on one surface of the mat-treated plastic film, From a bar code label for a rubber tire having a rubber-based pressure-sensitive adhesive layer (4) containing a vulcanization accelerator on its surface through a primer layer (3) and containing no vulcanizing agent, and before applying the bar code to the label. Label base material. [Effect] Individual management for each tire is possible in the production and distribution processes. |
