PROBLEM TO BE SOLVED: To provide an information display label having high heat resistance and excellent in flexibility, which is not peeled even when rubber goods or the like are deformed or elongated/contracted. SOLUTION: The information display label 1 is provided with a release sheet 6, an adhesive layer 5, a base material layer 3 and a surface layer 2 in this order. Elongation of the base material layer is 20% or more, and dimensional change of the base material layer obtained when removing drawing force after drawing the base material layer by 20% is 10% or less, and the dimensional change thereof obtained when removing drawing force after drawing it by 50% is 25% or less. Tensile strength obtained when the base material layer is elongated by 1% is equal to or above vulcanizing pressure of adherend rubber, and tensile strength per unit area obtained when the base material layer is elongated by 20 to 50% is equal to or above the vulcanizing pressure of the adherend rubber or larger than tensile strength obtained when vulcanized rubber of the adherend is drawn at the same elongation. By using the surface layer as a masking layer and the base material layer as a heat ray absorbing layer, marking by a laser marker can be performed. COPYRIGHT: (C)2011,JPO&INPIT |
