[Industrial Application Field] The present invention relates to an excellent label that can be attached to bottles to be collected and used, and is suitable for washing bottles. [Prior Art and its Problems] Conventional labels attached to beer bottles and the like have used materials consisting of paper alone or aluminum foil/paper. Among these, labels using aluminum foil are expensive, so labels with an aluminum vapor-deposited layer have come to be used as an alternative. However, labels made of paper or a material provided with an aluminum vapor-deposited layer have to use thicker paper as a base material than paper made of aluminum foil. This is because if thick paper is not used, the label will lack rigidity and will not be suitable for labeling.On the other hand, if thick paper is used, alkali such as caustic soda may be exposed to the back side of the paper during bottle washing. This method has the drawback that it takes a long time for the bottle washing liquid consisting of a solution to reach the bottle washing solution, which reduces the suitability for washing bottles. [Problem to be solved] A label made of paper or a base material having an aluminum vapor-deposited layer other than a label made of a material using aluminum foil, which is suitable for attaching tags and has excellent suitability for bottle washing. It's about getting a label. [Means for solving the problem] A gas-generating layer that generates gas by reacting with an alkaline solution on the back side of a base material made of paper with a predetermined treatment such as printing on the surface or paper with an aluminum vapor deposition layer. The suitability for bottle washing has been improved by providing this. [Function] When the bottle washing liquid made of an alkaline solution such as caustic soda solution heated during bottle washing reaches the gas generation layer through the base material, hydrogen gas from the gas generation layer reacts with the bottle washing liquid made of the alkaline solution. Occurs due to
This generated hydrogen gas promotes peeling between the label base material and the adhesive layer. [Example] An example of the present invention will be described according to the drawings. First, as shown in FIG. 1, a printing layer 4 and an overcoat layer 5 are provided on a base material 3 in which a clay coat layer 2 is provided on a base paper 1, and a bottle washing solution consisting of an alkaline solution such as a caustic soda solution is provided on the back side. This label is provided with a gas generating layer 6 made of a resin layer containing metal powder that reacts with hydrogen gas to generate hydrogen gas. In another embodiment, as shown in FIG. 2, on a base material 3 in which a clay coat layer 2 is provided on a base paper 1, a precoat layer 7, an aluminum vapor deposition layer 8, a primer layer 9,
A printing layer 4 and an overcoat layer 5 are sequentially provided,
This label is provided with a gas generating layer 6 on the back surface, which is made of a resin layer containing metal powder that reacts with a bottle washing liquid made of an alkaline solution such as caustic soda solution to generate hydrogen gas. Here, the printing layer 4 is composed of an ink using a nitrocellulose resin, a polyamide resin, or a mixed resin thereof as a vehicle and further adding maleic acid in an amount of 6% or less, and the overcoat layer 5 is This is a resin that is the vehicle for the ink used in layer 4. Moreover, the gas generation layer 6 provided on the back surface of the base material 3 is
Acrylic resin dispersion contains 1 to 50% by weight of metal powders such as aluminum, magnesium, and zinc that react with caustic soda to generate hydrogen gas.
It consists of a resin layer formed by coating and drying a mixture of the following. Furthermore, the precoat layer 7 is made of a nitrocellulose resin containing a fatty acid ester such as a phthalate ester, an adipate ester, or a sebacate ester.
~60% by weight, preferably 20~50% by weight of a mixed resin, or a copolymer resin containing methacrylic ester as a main component and further containing acrylic ester and acrylic acid, in which the acrylic acid is
The primer layer 9 is made of any one of a resin containing 15%, and the primer layer 9 is made of one of a Sierra resin, a nitrocellulose resin, a mixed resin in which a fatty acid ester is added to a nitrocellulose resin, and a resin in which an alkyd resin is further added to the mixed resin. Consisting of <Test Example 1> Methyl methacrylate/ethyl acrylate/butyl acrylate/acrylic acid was applied 50/20/on the back side of a base material with a clay coat layer on one side with a thickness of 65 g/ m2 .
0 aluminum powder in a dispersion containing 30% by weight of acrylic resin polymerized in a 20/10 ratio.
3.5 g/m 2 of each solution was applied by mixing 1 wt%, 1 wt%, 5 wt%, 10 wt%, and 20 wt%, and after drying to form a resin layer, each was cut into a size of 5 x 10 cm and tested. Pieces (A), (B), (C), (D), and (E) were created. 27 g of starch glue was applied on the resin layer of these test pieces.
m 2 coated, stuck on a beer bottle and dried in an oven at 40 °C. This beer bottle was immersed in a 45°C caustic soda solution at 80°C, and the time required for the test piece to peel off was measured. At this time, a test piece (F) consisting only of a base material without a resin layer
were also measured at the same time. The results are shown in Table 1.

The label of the present invention has the above structure, so
The so-called bottle washing time required to peel off the label from the bottle is approximately two-thirds or less of that of a conventional label without a gas-generating layer, and the time required for bottle washing is greatly shortened. It has also become possible to reduce the amount of bottle washing equipment. Additionally, in the case of labels with an aluminum vapor-deposited layer, the thickness of the aluminum vapor-deposited layer is approximately 1/20 of that of labels using conventional aluminum foil.
As a result, the amount of caustic soda consumed by aluminum during bottle washing is reduced to approximately 1/20.
Therefore, the amount of hydrogen gas generated has been reduced to approximately 1/20, improving the safety of the working environment and making it possible to reduce the capacity of the exhaust equipment.
