Abstract
An improved linerless pressure-sensitive label construction wherein label sheets carrying pertinent messages are pasted together with pressure-sensitive adhesive without using a release liner, and by separating the pasted-together label sheets, each separated section can be used as a label. Strips of release agent are provided at a given interval on the top and the bottom label sheets on their respective facing faces, the strips being arranged in a positionally staggered manner, so that the strips of release agent on one of the label sheets will come in contact with the strips of adhesive on the other. The strips of adhesive on either one of the label sheets are separated from one another by a narrow gap, so that the strips of adhesive which hold the top and the bottom label sheets together are separated from each other at the narrow gap and also from the strips of release agent on the other label sheet when the top and the bottom label sheets are peeled off from each other, whereby the label sheets can be easily separated.
