Sheet materials, labels fabricated from the sheet materials, and methods of fabricating the sheet material and forming the labels are provided. The sheet material for the label is composed of a heat-resistant base layer sandwiched between a heat-decomposable ink-receptive layer and a heat-decomposable pressure-sensitive adhesive (PSA) layer, with the surface of the ink-receptive layer and the exposed surface of the adhesive layer preferably covered with a release film. A heat-resistant marking such as an inked pattern can be applied to the surface of the ink-receptive layer, for example, using a carbon black thermal transfer ribbon. Upon heating the sheet material attached to an object at a temperature of about 300°C or greater, a burned pattern is obtained that is composed of the inorganic base sheet and the marking fused as a single body and bonded to the object. The burned-on label can be used, for example, as an identification label and a decorative design, among other applications. |
