[0007]
[Action]
An alkali-soluble, water-resistant coating layer is provided on the back side of the separable area of the paper label , so that the paper label does not soften due to water droplets adhering to the surface of the bottle, making the separable area easy. Can be separated. This makes it easy to separate the separable area by not applying the starch paste only to the back surface of the separable area. When starch paste is applied to the entire back surface of the paper label , a release agent layer is further provided on the coating layer provided on the back surface of the separable area, so that the starch paste is applied only to the back surface of the separable area. The separation is not performed, and the separable area can be separated.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a plan view showing an example of the paper label of the present invention, and FIG. 2 is a cross-sectional view showing a cross section taken along AA in FIG. Cutouts 2 and 2 are provided at two places on the upper side of the paper label 1, a separation line 3 connecting the cutouts 2 and 2 in a U-shape is provided, and a separable area 4 is formed. It is as follows. A clay coat layer 11 is provided on a base paper 10, and on the clay coat layer 11,
Precoat layer 12, an aluminum deposited layer 13, primer layer 14, sequentially provided a constituting the printing layer 15 and the overcoat layer 16, and the rear surface of the base paper 10 in the isolation region 4, the coating of the pre-coat layer 12 and the same type A coating layer 17 made of an agent is formed.
[0009]
Here, the base paper 10 needs to have an elongation in water of 2.5% or less, especially 1.5% or less when immersed in water. When cracks adhere, cracks or the like are generated in the deposited layer, the printed layer, and the overcoat layer, and the appearance is deteriorated. The pre-coat layer 12 is a pre-coating agent mainly containing any one of an amino alkyd resin, an amino alkyd modified phenol resin, a nitrocellulose resin and an acrylic resin. Specifically, in the case of a nitrocellulose resin, phthalic acid is used. Fatty acid esters such as esters, adipates and sebacates are mixed in the range of 20 to 50% by weight. In the case of an amino alkyd resin, maleic acid is mixed in a range of 5 to 10% by weight.
[0010]
The aluminum vapor-deposited layer 13 is formed in the range of 400 to 1000 °, and the primer layer 14 for providing the print layer 15 is an alkali-soluble resin, specifically, a material using a shellac resin or a nitrocellulose resin. The printing layer 15 is made of an ink using a nitrocellulose-based resin, a polyamide-based resin, or a mixed resin thereof as a vehicle. Further, for the overcoat layer 16, a coating agent made of a resin used as a vehicle for the printing layer 15 is used. The coating layer 17 is provided by applying the same coating agent as that of the precoat layer 12.
[0011]
