ABSTRACT:
This invention relates to a label continuum comprising a long label substrate, a pressure-sensitive adhesive layer formed by transferring to the back of the label substrate and a release layer formed on the surface of the label substrate, and in the invention the label substrate is rolled up such that the release layer and the pressure-sensitive adhesive layer are false-stuck to each other.
The invention also relates to a producing method for the label continuum which comprises a step 1 of preparing a process sheet having a release layer at least on either surface and forming a pressure-sensitive adhesive layer on the release surface of the process sheet, a step 2 of preparing a long label substrate with the back the pressure-sensitive adhesive layer is transferred and stuck to and of mating together the back of the label substrate and the pressure-sensitive adhesive layer of the process sheet, a step 3 of forming a release layer on the surface of the label substrate, a step 3 of forming a release layer on the surface of the label substrate, a step 4 of releasing only the process sheet from the surface of the pressure-sensitive adhesive layer transferred to the back of the label substrate, and a step 5 of rolling up the label substrate so that the release layer and the pressure-sensitive adhesive layer are false-stuck to each other.
