Abstract:
1. A heat-resistant, multi-layer label comprising: A. An ink-receptive layer comprising an acrylic-based polymer and first and second planar surfaces; B. A base layer comprising first and second planar surfaces, the first planar surface of the base layer in intimate contact with the second planar surface of the ink-receptive layer, the base layer consisting essentially of inorganic powder and an organic binder at a weight ratio of about 4 to about 6; and C. A pressure sensitive adhesive (PSA) layer comprising an acrylic-based polymer and first and second planar surfaces, the first planar surface of the PSA layer in intimate contact with the second surface of the base layer; with the proviso that the label is free of both glass frit and silicone, and that the label will withstand a temperature of 700° C. or more.
