ABSTRACT:
A seal comprising a substrate which is at least translucent to light having a transparent masking material disposed in an indicia-defining pattern on the inner surface of the substrate. A colorant layer is disposed over the masking material and extends beyond the pattern. There is an adhesive disposed at least over the area of the colorant. The present invention also includes a tamper indicating opaque container such as an envelope or carton has a window defined within the closure flap. A translucent or transparent panel overlaying the window has a transparent masking material of low adhesion properties disposed in an indicia-defining pattern. A colorant layer is disposed over the transparent masking material and an adhesive in turn is disposed over the colorant layer and transparent masking material. Upon unsealing of the closure flap, the adhesive dislodges the colorant from the panel within the area of the indicia-defining pattern defined by said masking material with the dislodged material remaining on the container, forming two tamper indicating indicia.
