[0003]

In the case of such a so-called heat-activatable pressure-sensitive adhesive layer formed, it can be wound and used without using a release paper. That is, before the adhesive is heated and melted to give pressure sensitivity, it does not have adhesiveness, so that it does not adhere even when wound in a roll shape. However, in this conventional non-separable label, the manufacturing equipment is inevitably large, the capital investment is large, and the label must be heated to activate the heat-adhesive adhesive. As a base material, there is no choice but to select a material having excellent heat resistance such as paper.

[0020]

According to the invention of claim 1, since the adhesive layer is formed on the back surface of the label substrate, the adhesive layer can be formed on the surface of the label substrate at room temperature. Therefore, when selecting a label base material, even an extremely thin tape with relatively low heat resistance can be used, and the solvent of the adhesive in the dissolved state before the adhesive layer is originally formed is transferred. Since it is removed before being applied, the range of selection of the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer can be expanded regardless of the property of the label substrate. Further, in particular, as the label base material, a material such as thermal paper that develops heat can be selected, and it can be applied to any printer such as a printer that prints on a transfer foil that is relatively heated.

According to the second aspect of the present invention, the print layer is formed on the surface of the label substrate, and the release agent is printed on the surface of the print layer.
Since the release layer is formed by coating, the label base material is rolled up so that the adhesive layer formed on the back surface of the label base material and the release layer formed on the front surface face each other and are temporarily attached. However, the label can be rewound and the label can be cut and used one by one from the label continuum.

According to the third aspect of the present invention, the printing layer is formed on the surface of the label substrate, and the film or sheet having excellent releasability is laminated on the surface of the label substrate to form the releasing layer. Therefore, even if the label base material is rolled up so that the release layer formed on the front surface side of the label base material and the adhesive layer formed on the back surface side face each other and temporarily adhere, it is possible to rewind, The label continuum can be cut into individual labels for use.

According to the invention of claim 4, the surface of the long-sized label base material, which comprises an adhesive layer formed on the releasable surface of the process sheet and a surface to which the adhesive layer is transferred and adhered. Are overlapped with each other, and the adhesive layer is transferred from the surface of the process sheet to the back surface of the long label base material at room temperature,
The pressure-sensitive adhesive layer can be formed even with an extremely thin label substrate having relatively low heat resistance. In addition, since the solvent contained when the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer is in the emulsion state is removed and transferred from the surface of the process sheet to form the pressure-sensitive adhesive layer, the solvent affects the label substrate. Will not be affected. Therefore, the range of selection of the pressure-sensitive adhesive for forming the label base material and the pressure-sensitive adhesive layer becomes extremely wide, and it is suitable for the production of a wide variety of products in small quantities. Moreover, since the process sheet can be used many times, it is possible to reuse resources without becoming waste.

If the adhesive layer is formed as a label base material having a plurality of desired widths from the beginning, useless portions are generated on both side edges of each label base material. According to this, a label substrate and a process sheet which are wider and longer than the intended label substrate width are first prepared, and they are laminated with an adhesive layer, and they are arranged in an appropriate width. By slitting to form the desired label substrate, the pressure-sensitive adhesive layer formed on the releasable surface of the process sheet can be formed leaving the left and right ends of the process sheet slightly. It is extremely useful because it can produce a label base material having a desired width in the initial stage with a small amount of wasteful edges.

According to the sixth aspect of the present invention, a wide and long label base material and a process sheet are prepared, they are laminated with an adhesive layer, and the label base material is die-cut into an appropriate width. If the appropriate label width is formed by the above, the initial target label can be appropriately formed,
Extremely useful.

According to the invention of claim 7, if the pressure-sensitive adhesive layer is formed on the releasable surface of the process sheet and the pressure-sensitive adhesive layer is transferred and superposed on the back surface of the long label substrate to which the pressure-sensitive adhesive layer is bonded. The pressure-sensitive adhesive layer can be transferred from the process sheet to the back surface of the long label substrate by the action of the process sheet having excellent releasability.

According to the invention of claim 8, if a pressure-sensitive adhesive layer is formed on the releasable surface of the process sheet and the pressure-sensitive adhesive layer is transferred and adhered to the back surface of the long label substrate to be adhered. The pressure-sensitive adhesive layer can be transferred from the process sheet to the back surface of the long label substrate by the action of the process sheet having excellent releasability.
