ABSTRACT:
A tamper-evident label is disclosed having a base label substrate with an adhesive on its lower surface. Water-insoluble indicia are applied to the upper surface of the base label substrate. Water-soluble indicia or graphics are applied to at least the water-insoluble indicia. When exposed to water, the water-soluble indicia or graphics dissolve, and the water-insoluble indicia are revealed. The label further includes a plurality of perforations such that removal of the label from an application surface causes the label to fragment.
