Abstract
A piggyback label construction includes a first label having a stock ply with a bottom face having pressure sensitive adhesive, and an imagable top face. A second label comprises a stock ply having a bottom face with pressure sensitive adhesive, a top face with a continuous image-producing coating, and a continuous adhesive release coating over the image-producing coating. The image-producing coating preferably is a thermosensitive coating having a first heat activation temperature of about 140.degree.-250.degree. F. (preferably about 145.degree.-155.degree. F). The first label stock ply has a weight of about 30 lbs. per 1000 sheet 11'.times.17' ream, or less (preferably about 18-30 lbs.). The first label stock imagable top face preferably is a second thermosensitive coating having a higher heat activation temperature than the first heat activation temperature. The image-producing coating may comprise a self-contained coating. The first label may be offset from the second label to provide an exposed portion of the second label image-producing portion which is separated from the rest of the construction by a perforation line, and having pre-printed non-variable indicia.
