Description

  The present invention relates to a heat-sensitive seal label, a heat-sensitive seal set, and a heat-sensitive seal roll used for a seal label or the like attached to a product.

  Conventionally, as a heat-sensitive seal label that is generally used for various purposes such as sticking to a product, it has an adhesive layer on the back side of the thermal paper for the label and is wound in a roll shape through a non-adhesive release paper. Those that are stored in a stacked state are known. Since such a heat-sensitive seal label requires a release paper, there is a problem that the release paper becomes dust when the label is attached, and the cost is increased by the amount of the release paper.

  Therefore, a heat-sensitive seal label is also known that does not require a release paper by forming a release layer on the thermosensitive coloring layer on the surface of the thermal paper for labels and forming an adhesive layer on the back surface (Patent Document 1). reference).

  However, in the case of the above-mentioned heat-sensitive seal label, there is a problem that when the silicone resin as the release material is directly formed on the heat-sensitive color forming material layer of the thermal paper for labels, the silicon resin is not cured by the reaction between the two. For this reason, it is necessary to form a sealing layer between the heat-sensitive color former layer and the silicon resin. However, in the case of thermal paper using high-quality paper that is currently widely used, the thickness of the sealing layer and the release layer is kept at 2 microns or less, which reduces the color of the thermal paper, because the surface is relatively rough. There is a problem that a certain color cannot be obtained when printing or the like on a seal label.

And a pressure-sensitive adhesive layer provided at a portion corresponding to the non-stick layer on the back side of the thermal paper.

  The non-adhesive layer is composed of, for example, a sealing layer coated on a portion other than the portion on which the surface of the thermal paper is to be colored, and a release material layer coated on the sealing layer.

  In such a configuration, the non-adhesive layer is provided so as to avoid the portion where the color of the thermal paper is to be developed. It is possible to provide a seal label.

  Further, the non-adhesive layer and the adhesive material layer may be applied on the thermal paper at a temperature lower than the color development temperature of the heat-sensitive color development layer.

  A heat-sensitive seal set according to an embodiment of the present invention is configured by stacking a plurality of heat-sensitive seal labels as described above.

  A heat-sensitive seal roll according to an embodiment of the present invention is a tape-shaped roll of the above-mentioned heat-sensitive seal label in which a non-adhesive layer and an adhesive material layer are formed on a portion other than a portion to be developed in the width direction. It is configured to turn.
