## Abstract

A self-expiring badge or label that includes an upper substrate having an upper surface and a lower surface and an adhesive activator layer on the lower surface. A protective layer having a first surface and a second surface is provided, with the first surface of the protective layer being removably attached to and overlaying the adhesive layer. A lower substrate is provided that has an upper surface and a lower surface, the upper surface being removably attached to and overlaying the second surface of the protective layer. A migrating ink pattern is on the lower surface of the lower substrate. To activate, the upper substrate and at least a portion of the lower substrate are removed from the protective layer to leave a remaining portion of the lower substrate having the migrating ink pattern thereon. The migrating ink pattern is then contacted with the exposed adhesive activator layer to activate the migrating ink pattern to migrate through the adhesive activator layer and upper substrate in a selected time interval for viewing from the upper surface of the upper support layer to indicate an expired badge or label. Preferably the migrating ink pattern is contacted with the adhesive layer by folding it onto the adhesive layer. Optionally, to activate the badge both substrates are completely removed from the protective layer and the migrating ink pattern is contacted with the adhesive layer.

## Claims

### Claim 1

A self-expiring badge or label comprising:
an upper substrate having an upper surface and a lower surface,
an adhesive activator layer on the lower surface,
a protective layer having a first surface and a second surface, the first surface removably attached to and overlaying the adhesive layer,
a migrating ink pattern on the second surface of the protective layer,
whereby removing the upper substrate and at least a portion of the protective layer leaves a remaining portion having the migrating ink pattern thereon, and contacting the migrating ink pattern to the exposed adhesive activator layer on the lower surface of the upper substrate to activate the migrating ink pattern to migrate through the adhesive activator layer and upper substrate in a selected time interval for viewing from the upper surface of the upper substrate layer to indicate an expired badge or label.

### Claim 2 (depends on 1)

The self-expiring badge or label of claim 1, wherein the migrating ink pattern is contacted to a portion of the exposed adhesive activator layer, the remaining portion of the exposed adhesive activator layer for adhesively mounting the badge or label to a surface.

### Claim 3 (depends on 1)

The self-expiring badge or label of claim 1, wherein the remaining portion of the protective layer having the migrating ink pattern thereon is folded to contact the migrating ink pattern to the exposed adhesive activator label.

### Claim 4 (depends on 1)

The self-expiring badge or label of claim 1, wherein the remaining portion of the protective layer having the migrating ink pattern thereon is folded to contact the migrating ink pattern to a portion of the exposed adhesive activator layer, the remaining portion of the exposed adhesive activator layer for adhesively mounting the badge or label to a surface.
