Therefore, for the same reason as the label 10 of Embodiment 1, it is possible to suppress deterioration of the design of the appearance of the label 10.
  • the label 10 of embodiment 2 is able to suppress the occurrence of blocking (a phenomenon in which, in a label roll on which the label 10 is wound, the aqueous ink on the first surface 1a side of the substrate 1 of the label 10 transfers to the substrate 1 of another label 10 located directly above or below the label 10, causing the labels 10 located above and below to stick to each other, making it difficult to unwind the label 10 from the label roll) compared to the label 10 of embodiment 1.
  • blocking a phenomenon in which, in a label roll on which the label 10 is wound, the aqueous ink on the first surface 1a side of the substrate 1 of the label 10 transfers to the substrate 1 of another label 10 located directly above or below the label 10, causing the labels 10 located above and below to stick to each other, making it difficult to unwind the label 10 from the label roll
  • the occurrence of blocking can be further suppressed by including a hardener in the aqueous ink used to form the second marking 5, thereby increasing the hardness of the second marking 5 after the aqueous ink has dried.
  • the second display 5 containing the lubricant may be formed by including a lubricant in the aqueous ink used to form the second display 5.
  • a lubricant it is possible to improve the ease of attaching the label 10 of the second embodiment to a container or the like.
  • the second display 5 does not contain a lubricant, from the viewpoint of improving the attachability of the label 10 of the second embodiment to a container or the like, it is preferable to use the base material 1 as shown in FIG. 2 or 3, for example.
  • the area of the second display 5 occupying the surface of the second printed base layer 4 is 50% of the area of the surface of the second printed base layer 4. % or less.
  • the label 10 of Embodiment 2 can be manufactured, for example, as follows. First, the first display 2 is formed on the first surface 1a of the base material 1. Next, a first printing base layer 3 is formed on the first display 2 . The steps up to this point are the same as the label manufacturing method of Embodiment 1.
  • a second printed base layer 4 is formed on the first printed base layer 3.
  • the second printed base layer 4 has an area larger than the area of the first printed base layer 3 in a plan view from the first surface 1a side or the second surface 1b side of the base material 1, and also has a larger area than the second printed base layer 3. It can be formed by printing the aqueous ink for forming No. 4 on the first printing base layer 3 by letterpress printing, preferably flexo printing so as to contact the first printing base layer 3, and then drying it.
  • the aqueous ink for forming the second printing base layer 4 contains a curing agent included in the above-mentioned second indication 5 together with the resin.
  • the resin contained in the aqueous ink for forming the second printing base layer 4 it is preferable to use, for example, a urethane thermoplastic resin or an acrylic thermoplastic resin having a hydroxyl group, a carboxy group, an amino group, or a carbonyl group.

  • an aziridine-based curing agent can be used as the curing agent that can be included in the aqueous ink.
  • water-based ink 5a used to form the second display 5 is printed on the second printing base layer 4 by letterpress printing, preferably flexography.
