れる場所での使用に適さず、苛酷な条件下で使用
されるラベルとしては、適さず、その用途も限定
され、実用化の大きな障害となつている。 Conventional heat-sensitive color-forming labels use water-soluble materials that have a color-forming function, so they do not have weather resistance against moisture, etc. Moreover, they develop color when heated, so they do not have a color-forming function at the time of manufacture. After applying the material, it is dried without much heating, which takes time to dry and also reduces weather resistance.
In order to ensure water resistance, etc., a solvent-based material may be used as a material having a color-forming function, but in that case, the solvent has the property of degrading the color-forming agent itself and cannot be used. Therefore, it has poor chemical resistance and solvent resistance, and is not suitable for use in places where chemical or solvent resistance is required, and is not suitable as a label to be used under harsh conditions. This is a major obstacle to practical application.
本考案は、かかる事情に鑑みてなされたもの

色性のラベルを提供せんとするものである。 The present invention was developed in view of the above circumstances, and eliminates the various drawbacks of conventional labels.Drying of the heat-sensitive coloring material is easy during production, increasing label production efficiency, and making it easy to use in frozen cases, etc. It can also be used as a label that is used under harsh conditions such as heat-sensitive coloring materials, reducing the chances of moisture or humidity coming into contact with the heat-sensitive coloring materials, and reducing the chances of chemicals, etc. coming into contact with the heat-sensitive coloring materials, thereby preventing deterioration of the heat-sensitive coloring materials. The object of the present invention is to provide a heat-sensitive color-developing label that prevents this.
以下、本考案を図面に基づき具体的に説明す

A heat-sensitive element 4 made of an acidic substance or the like that causes the dye 3 to develop color is used as a core material, and the core material is encapsulated with a film-forming material 5 such as a heat-softening resin to form microcapsules, and the core material is encapsulated in a binder. The labels are dispersed and isolated and applied to the surface of the label base material 1. When heat is applied, the wall material surrounding the microencapsulated core material is dissolved, and the dye 3 and the heat-sensitive element 4 come into contact to cause a chemical reaction, resulting in color development.

でよい。 6 is a protective layer formed by curing an electron beam curing material laminated on the surface of the thermosensitive coloring layer 2 by electron beam irradiation. Examples of electron beam curable materials include polyester resins, acrylates, and
The protective layer is made of a prepolymer having ethylenically unsaturated bonds such as methacrylates and a reactive diluent, and is coated with the electron beam curable material using a printing method such as gravure printing, offset printing, or screen printing. Ru. The electron beam curable material coated on the surface of the thermosensitive coloring layer 2 may be cured using a commercially available low energy electron accelerator. The amount of electron beam irradiation at this time may be an absorbed dose sufficient to harden the electron beam curable material.
７は、ラベル基材１の裏面に形成された粘着剤

It may be formed by punching out the release sheet 8 to the extent that it reaches the surface but does not damage it, and then peeling off unnecessary parts from the release sheet 8.

くなる。 The present invention is configured as described above, and the protective layer made of an electron beam curing material cured by electron beam irradiation is provided on the surface of the thermosensitive coloring layer, so that the thermosensitive coloring layer is protected by the protective layer. If electron beam curable resin is used as a protective layer, it will be chemically stable and will not affect the coloring agent, making it water resistant and
It is possible to obtain labels with excellent weather resistance, chemical resistance, and solvent resistance, which can improve productivity. It can be used as a label that is exposed to harsh conditions, and its range of use is extremely wide as barcode labels and the like.
