ABSTRACT:
This invention relates to a label continuum comprising a long label substrate, an adhesive layer formed on the back thereof, a heat-sensitive developing layer formed on the surface of the label substrate and a release layer formed on the surface of the label substrate opposite to the adhesive layer when the label substrate is rolled up.
The invention also relates to a producing method of the label continuum which comprises a step 1 of preparing a process sheet with at least either surface thereof having a releasability and forming an adhesive layer on the release surface of the process sheet, a step 2 of preparing a long label substrate with the back to which the adhesive layer is transferred and stuck and of mating together the back of the label substrate and the adhesive layer of the process sheet, 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 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 adhesive layer are false-stuck to each other.
