Abstract
A pressure-sensitive pharmaceutical label which cannot be removed with steam or water from a container once the label is applied, the label incorporating a combination of an image-producing self-contained carbonless pressure-sensitive label with an overlaminate having an opaque design on a portion of the surface thereof, such that any information subsequently printed on the overlaminated label will be obscured from view at the position having an opaque design.

A label comprising:
- backing paper having first and second major surfaces, at least one of said major surfaces having a release coating thereon;
- a first permanent, pressure-sensitive adhesive layer formed on a selected portion of said release coating;
- carbonless paper contiguous to said first permanent pressure-sensitive adhesive layer, said carbonless paper having first and second major surfaces;
- a second clear permanent, pressure-sensitive adhesive layer covering said carbonless paper;
- clear laminate means applied to said second permanent pressure-sensitive adhesive layer for protecting said carbonless paper;
- and
- an opaque coating on the surface of said laminate means for obscuring the visibility of any information contained on a selected portion of said carbonless paper.

- backing paper having first and second major surfaces, at least one of said major surfaces having a release coating thereon;
- a first permanent, pressure-sensitive adhesive layer formed on a selected portion of said release coating, said first permanent pressure-sensitive adhesive layer containing an opaque die;
- carbonless paper contiguous to said first permanent pressure-sensitive adhesive layer, said carbonless paper having first and second major surfaces;
- a second clear permanent, pressure-sensitive adhesive layer covering said carbonless paper;
- clear laminate means applied to said second clear permanent, pressure-sensitivie adhesive layer for protecting said carbonless paper from moisture damage, tampering and the like;
