  • Patent number: 5154448
    Abstract: A layered label for containers and the like. The label has for the outermost layer, a thin scratchable surface that when scratched, reveals a contrasting color below. By scratching through the surface of the label, one may legibly write information on the label. The label allows consumers to conveniently record information on an article with a fingernail and therefore without the need for a writing implement. The label may be a single layer of scratchable coating over a contrasting color on the surface of the container, or it may be three layers, in which the scratchable coating is the top layer applied over a base label of contrasting color with pressure sensitive adhesive and a peel away backing on the bottom layer.
