Description
本発明はラベルに関するものである。具体的には、簡素な構成からなり、ラベルを被着体に貼着した後、該ラベルを被着体から剥がす際に易破壊層が意図した模様状に破壊して被着体上にその形状が残り、該残留物によりラベルが剥離されたことを肉眼で容易に判別することが可能であるラベルに関するものである。 The present invention relates to labels. Specifically, it consists of a simple structure, after sticking the label to the adherend, the easy-breaking layer breaks into the intended pattern when the label is peeled off the adherend, and the label is placed on the adherend. The present invention relates to a label that can be easily determined with the naked eye that the shape remains and the label is peeled off by the residue.
従来、貼替防止を目的として、剥離した際に自身が破壊するラベルが複数提案されている。例えば特許文献１には、粉末フィラーと合成樹脂バインダーからなり剥離時に凝集破壊する凝集破壊層に粘着剤層を積層した貼替防止ラベルが提案されている。このラベルは、ラベル剥離時の凝集破壊層の破壊を主な目的としており、貼着後に剥離した際に凝集破壊層と粘着層とが被着体面方向に全面的に残るようになっている。そのため破壊されたことが分かりづらいという問題がある。
一方、特許文献２に記載の再貼付不正使用防止ラベルは、使用時に除去されるラベル基材と、前記ラベル基材の下側にパターン状に形成される剥離層と、前記剥離層の下側に形成される印刷層と、前記印刷層の下側に形成される粘着層とを含んでいる様態であり、貼着後に剥離した際に被着体にラベルの一部が残るようになっており、この残留物に印刷された情報を持たせることができる。しかしこれは非常に複雑な層構成を必要としており、且つパターン状の剥離層を形成することは容易ではないことから製造工程数が多くなりコスト高となるという問題がある。
また、引用文献３に記載の脆質ラベルは、基材、破壊層および粘着層からなるものであり、粘着層が凹凸を成し、該ラベルを被着体に貼着後に剥離すると、粘着層の少なくとも凸部に対応した部分の破壊層が被着体に残留することで、粘着層の凹凸に対応して破壊層が破壊されるものである。この場合でも破壊を肉眼で容易に判別するために破壊層が有色層或いは金属光沢層等を更に有する必要があり、製造工程数が多くなりコスト高となる問題がある。また粘着剤が連続した層の中で凹凸を形成している場合には、破壊の際に粘着剤層の破断も必要になることから、剥離に要する応力ならびに被着体に残存する部分の形状が安定しないという問題がある。
2. Description of the Related Art Conventionally, for the purpose of preventing replacement, a plurality of labels that can be destroyed when peeled have been proposed. For example, Patent Document 1 proposes an anti-replacement label in which a pressure-sensitive adhesive layer is laminated on a cohesive failure layer that is made of a powder filler and a synthetic resin binder and cohesively breaks at the time of peeling. The main purpose of this label is to destroy the cohesive failure layer when the label is peeled off, and the cohesive failure layer and the adhesive layer remain entirely in the direction of the adherend when peeled off after sticking. For this reason, there is a problem that it is difficult to understand that it has been destroyed.
On the other hand, the reattachment illegal use prevention label described in Patent Document 2 includes a label base material to be removed at the time of use, a release layer formed in a pattern on the lower side of the label base material, and a lower side of the release layer And a pressure-sensitive adhesive layer formed on the lower side of the print layer, and a part of the label remains on the adherend when peeled off after sticking. The printed information can be given to the residue. However, this requires a very complicated layer structure, and it is not easy to form a patterned release layer, so that there is a problem that the number of manufacturing steps increases and the cost increases.
Moreover, the brittle label described in the cited document 3 is composed of a base material, a fracture layer and an adhesive layer, and the adhesive layer is uneven, and when the label is peeled off after being attached to an adherend, the adhesive layer The destruction layer of at least the part corresponding to the convex part remains on the adherend, so that the destruction layer is destroyed corresponding to the unevenness of the adhesive layer. Even in this case, it is necessary that the destruction layer further has a colored layer or a metallic luster layer in order to easily discriminate the destruction with the naked eye, resulting in a problem that the number of manufacturing steps increases and the cost increases. Also, if the adhesive forms irregularities in a continuous layer, the adhesive layer must be broken at the time of breaking, so the stress required for peeling and the shape of the part remaining on the adherend There is a problem that is not stable.
本発明は、成形が容易な簡素な構成からなり、ラベルを被着体に貼着した後にラベルを被着体から剥がす際に易破壊層が意図した模様状に破壊して被着体上にその形状が残り、該残留物によりラベルが剥離されたことを肉眼で容易に判別することができるラベルを提供することを課題とする。 The present invention has a simple configuration that is easy to mold, and when the label is peeled off from the adherend after the label has been attached to the adherend, the easily breakable layer breaks into the intended pattern on the adherend. It is an object of the present invention to provide a label that can be easily identified with the naked eye that the shape remains and the label is peeled off by the residue.
本発明は、以下の手段により課題を解決するものである。
即ち本発明は、基材層（Ａ）、易破壊層（Ｂ）、および有色接着剤層（Ｃ）をこの順で含み、それぞれの層の中で易破壊層（Ｂ）の凝集力が最も小さく、有色接着剤層（Ｃ）が易破壊層（Ｂ）上に３０〜９５％の面積割合でパターン状に設けられており、且つそのパ
ターンの最小単位が０．１〜３０５ｍｍのピッチを有していることを特徴とするラベルに関するものである。
The present invention solves the problem by the following means.
That is, the present invention includes a base material layer (A), an easily breakable layer (B), and a colored adhesive layer (C) in this order, and the cohesive force of the easily breakable layer (B) is the most among these layers. A small colored adhesive layer (C) is provided in a pattern with an area ratio of 30 to 95% on the easily breakable layer (B), and the minimum unit of the pattern has a pitch of 0.1 to 305 mm. It is related with the label characterized by doing.
該ラベルの易破壊層（Ｂ）は熱可塑性樹脂、ならびに無機微細粉末および有機フィラーの少なくとも一方を２０〜７５重量％含み、少なくとも一軸方向に延伸された多孔質の樹脂フィルム層であり、その凝集力が５〜１５０ｇ／ｃｍ幅であることが好ましく、易破壊層（Ｂ）に用いる該熱可塑性樹脂はポリオレフィン系樹脂を含むことが好ましい。
該有色接着剤層（Ｃ）は着色剤と、感圧接着剤、ディレード型接着剤、ホットメルト型接着剤、再湿型接着剤のいずれか一つからなり、その凝集力が２０〜１０００ｇ／ｃｍ幅であることが好ましく、有色接着剤層（Ｃ）に用いる該着色剤は無機顔料、有機顔料、および染料の少なくとも一つを含むことが好ましい。
該基材層（Ａ）は熱可塑性樹脂、ならびに無機微細粉末および有機フィラーの少なくとも一方を０．１〜５０重量％含み、その含有量が易破壊層（Ｂ）における無機微細粉末および有機フィラーの含有量よりも８重量％以上少ない樹脂フィルム層であり、その凝集力が５０〜１５０００ｇ／ｃｍ幅であることが好ましい。
本発明のラベルは該易破壊層（Ｂ）と該有色接着剤層（Ｃ）との間に更に印刷層（Ｄ）を積層しても良く、該有色接着剤層（Ｃ）側の表面に更に剥離紙（Ｅ）を積層しても良い。
The easily breakable layer (B) of the label is a porous resin film layer containing 20 to 75% by weight of at least one of a thermoplastic resin, an inorganic fine powder and an organic filler, and stretched in at least a uniaxial direction. The force is preferably 5 to 150 g / cm width, and the thermoplastic resin used for the easily breakable layer (B) preferably contains a polyolefin resin.
The colored adhesive layer (C) comprises any one of a colorant, a pressure sensitive adhesive, a delayed adhesive, a hot melt adhesive, and a rewet adhesive, and the cohesive strength thereof is 20 to 1000 g / The width is preferably cm, and the colorant used in the colored adhesive layer (C) preferably contains at least one of an inorganic pigment, an organic pigment, and a dye.
The base material layer (A) contains 0.1 to 50% by weight of a thermoplastic resin and at least one of inorganic fine powder and organic filler, and the content of the inorganic fine powder and organic filler in the easily breakable layer (B). The resin film layer is preferably 8% by weight or less less than the content, and the cohesive strength is preferably 50 to 15000 g / cm width.
In the label of the present invention, a printing layer (D) may be further laminated between the easily breakable layer (B) and the colored adhesive layer (C), and on the surface of the colored adhesive layer (C) side. Further, release paper (E) may be laminated.
本発明のラベルによれば、ラベルを被着体に貼着した後にラベルを被着体から剥がす際に、ラベルの有色接着剤層（Ｃ）が積層されている部分は易破壊層（Ｂ）の層内破壊により剥離が進行するが、有色接着剤層（Ｃ）が積層されていない部分は易破壊層（Ｂ）が破壊することなく剥離が進行する。結果として、ラベルの剥離により有色接着剤層（Ｃ）が積層されている部分は有色接着剤層（Ｃ）が易破壊層（Ｂ）とともに被着体側に残り、有色接着剤層（Ｃ）が積層されていない部分は被着体側には何も残存しない。易破壊層（Ｂ）が意図した模様状に破壊して被着体上にその形状が残り、且つ同残留物が被着体外観やラベル外観と比べて着色して見えることから、ラベルが剥離されたことを肉眼で容易に判別することが可能である。
また本発明のラベルは成形が容易な簡素な構成からなり、従来のラベルに比べて安価に製造することが可能である。
According to the label of the present invention, when the label is peeled off from the adherend after the label is adhered to the adherend, the portion where the colored adhesive layer (C) of the label is laminated is the easily breakable layer (B). Peeling proceeds due to the in-layer destruction of the layer, but peeling proceeds without breaking the easily breakable layer (B) in the portion where the colored adhesive layer (C) is not laminated. As a result, the colored adhesive layer (C) remains on the adherend side together with the easily breakable layer (B) in the portion where the colored adhesive layer (C) is laminated by peeling off the label, and the colored adhesive layer (C) No part of the non-stacked portion remains on the adherend side. The easy-breaking layer (B) breaks into the intended pattern and the shape remains on the adherend, and the residue appears colored compared to the adherend appearance and label appearance. It is possible to easily discern what has been done with the naked eye.
Further, the label of the present invention has a simple structure that can be easily molded, and can be manufactured at a lower cost than conventional labels.

基材層（Ａ）はラベルにおいてそれ自体の強度が高く、（Ａ）層を持って引き剥がしたときに、それ自体は破壊しないものである。
また基材層（Ａ）は、ラベルを被着体に貼付している際に最外層となるものである。
基材層（Ａ）は印刷適性、強度、耐水性、耐久性を有する紙材、樹脂フィルム等を採用し得るが、熱可塑性樹脂からなる層であることが好ましい。
[Base material layer (A)]
The base material layer (A) has high strength in the label, and when the base material layer (A) is peeled off with the (A) layer, the base material layer (A) does not break itself.
The base material layer (A) is the outermost layer when the label is attached to the adherend.
As the base material layer (A), paper materials, resin films, and the like having printability, strength, water resistance, and durability can be adopted, but a layer made of a thermoplastic resin is preferable.
熱可塑性樹脂としては、高密度ポリエチレン、中密度ポリエチレン、低密度ポリエチレン等のエチレン系樹脂、あるいはプロピレン系樹脂、ポリメチル−１−ペンテン、エチレン−環状オレフィン共重合体等のポリオレフィン系樹脂、ナイロン−６、ナイロン−６，６、ナイロン−６，１０、ナイロン−６，１２等のポリアミド系樹脂、ポリエチレンテレフタレート、ポリエチレンナフタレート、ポリブチレンサクシネート、ポリ乳酸、およびこれらのモノマーに共重合可能な他のモノマーと共重合した脂肪族ポリエステル等の熱可塑性ポリエステル系樹脂、ポリカーボネート、アタクティックポリスチレン、シンジオタクティックポリスチレン、ポリフェニレンスルフィド等の熱可塑性樹脂が挙げられる。これらは２種以上混合して用いることもできる。これらの中でも、ポリオレフィン系樹脂を用いることが好ましい。更にポリオレフィン系樹脂の中でも、コスト面、耐水性、耐薬品性の面からプロピレン系樹脂、高密度ポリエチレンがより好ましい。 Examples of the thermoplastic resin include ethylene resins such as high density polyethylene, medium density polyethylene, and low density polyethylene, or polyolefin resins such as propylene resin, polymethyl-1-pentene, and ethylene-cyclic olefin copolymer, and nylon-6. Polyamide resins such as nylon-6,6, nylon-6,10, nylon-6,12, polyethylene terephthalate, polyethylene naphthalate, polybutylene succinate, polylactic acid, and other copolymerizable with these monomers Examples thereof include thermoplastic polyester resins such as aliphatic polyester copolymerized with monomers, and thermoplastic resins such as polycarbonate, atactic polystyrene, syndiotactic polystyrene, and polyphenylene sulfide. These may be used in combination of two or more. Among these, it is preferable to use polyolefin resin. Further, among polyolefin resins, propylene resins and high density polyethylene are more preferable from the viewpoints of cost, water resistance, and chemical resistance.
かかるプロピレン系樹脂としては、プロピレン単独重合体でありアイソタクティックないしはシンジオタクティックおよび種々の程度の立体規則性を示すポリプロピレン、プロピレンを主成分とし、これと、エチレン、ブテン−１、ヘキセン−１、ヘプテン−１，４−メチルペンテン−１等のα−オレフィンとの共重合体が使用される。この共重合体は、２元系でも３元系でも４元系でもよく、またランダム共重合体でもブロック共重合体であってもよい。 Such propylene-based resins are propylene homopolymers, mainly composed of polypropylene and propylene which are isotactic or syndiotactic and have various degrees of stereoregularity, and ethylene, butene-1, hexene-1 Copolymers with α-olefins such as heptene-1,4-methylpentene-1 are used. This copolymer may be a binary system, a ternary system, or a quaternary system, and may be a random copolymer or a block copolymer.
これら熱可塑性樹脂から得られる基材層（Ａ）は、一軸延伸あるいは二軸延伸されていても良い。基材層（Ａ）の肉厚は通常１０〜５００μｍ、好ましくは２０〜３００μｍの範囲である。１０μｍ未満では基材層（Ａ）の破断強度が低く、基材層（Ａ）を持って易破壊層（Ｂ）から引き剥がす際に、途中でラベルが破断してしまい本発明の所期の性能を発揮しづらい。又、５００μｍを越えてしまうと該層の腰が高くなり、剥がし易さや印刷適性が低下する。 The base material layer (A) obtained from these thermoplastic resins may be uniaxially stretched or biaxially stretched. The thickness of the base material layer (A) is usually in the range of 10 to 500 μm, preferably 20 to 300 μm. If it is less than 10 μm, the base layer (A) has a low breaking strength, and when the base layer (A) is held and peeled off from the easily breakable layer (B), the label breaks in the middle, and the intended effect of the present invention is reached. Difficult to demonstrate performance. On the other hand, if it exceeds 500 μm, the stiffness of the layer increases, and the ease of peeling and the printability deteriorate.
基材層（Ａ）は無機微細粉末または有機フィラーの少なくとも一方を含有していても良く、含有していなくても良い。
基材層（Ａ）が無機微細粉末および有機フィラーの少なくとも一方を含有していれば、基材層（Ａ）が不透明となり、ラベルの隠蔽性を高めることができる。逆に含有していなければ、基材層（Ａ）を通して有色接着剤層（Ｃ）が被着体からの剥離前でも視認できる。また、基材層（Ａ）への印刷や印刷層（Ｄ）の印刷絵柄を工夫して剥離前と剥離後の視認できる絵柄が変化するように工夫することもできる。
含有させる場合には、無機微細粉末として、平均粒径が通常０．０１〜１５μｍ、好ましくは０．０２〜８μｍ、更に好ましくは０．０３〜４μｍのものを使用することができる。具体的には、炭酸カルシウム、焼成クレイ、シリカ、けいそう土、タルク、酸化チタン、硫酸バリウム、アルミナなどの微細粉末を使用することができる。
The base material layer (A) may or may not contain at least one of inorganic fine powder and organic filler.
If the base material layer (A) contains at least one of the inorganic fine powder and the organic filler, the base material layer (A) becomes opaque and the concealability of the label can be improved. If not contained, the colored adhesive layer (C) can be visually recognized through the base material layer (A) even before peeling from the adherend. In addition, the printing on the base material layer (A) and the printing pattern on the printing layer (D) can be devised so that the visible pattern before peeling and after peeling can be changed.
When it is contained, an inorganic fine powder having an average particle size of usually 0.01 to 15 μm, preferably 0.02 to 8 μm, more preferably 0.03 to 4 μm can be used. Specifically, fine powders such as calcium carbonate, calcined clay, silica, diatomaceous earth, talc, titanium oxide, barium sulfate, and alumina can be used.
有機フィラーとしては、主成分である熱可塑性樹脂とは異なる種類の樹脂を選択することが好ましい。例えば、熱可塑性樹脂がポリオレフィン系樹脂である場合には、有機フィラーとしては、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリカーボネート、ナイロン−６，ナイロン−６，６、環状オレフィンの単独重合体や環状オレフィンとエチレンとの共重合体等で融点が１２０℃〜３００℃、ないしはガラス転移温度が１２０℃〜２８０℃を有するものを使用することができる。 As the organic filler, it is preferable to select a different type of resin from the thermoplastic resin that is the main component. For example, when the thermoplastic resin is a polyolefin-based resin, examples of the organic filler include polyethylene terephthalate, polybutylene terephthalate, polycarbonate, nylon-6, nylon-6,6, cyclic olefin homopolymer, and cyclic olefin and ethylene. And the like having a melting point of 120 ° C. to 300 ° C. or a glass transition temperature of 120 ° C. to 280 ° C. can be used.

More preferably, the content is less than%.
If it is in the said range, it is possible to hold | maintain the intensity | strength of a base material layer (A) high compared with the easily breakable layer (B) and colored adhesive layer (C) which are mentioned later.
As a result, the base material layer (A) preferably has a cohesive force of 50 to 15000 g / cm width, more preferably 100 to 12000 g / cm width, and particularly preferably 155 to 11000 g / cm width. preferable.

The multilayering of the base material layer (A) makes it possible to add various functions such as writability, printability, thermal transfer suitability, scratch resistance, and secondary processing suitability.
However, when the layer on the side in contact with the easily breakable layer (B) of the base material layer (A) is the layer (A1), the content of at least the inorganic fine powder and the organic filler in the same layer (A1) is as easy as above. It is preferably 8% by weight or more and more preferably 10% by weight or more less than the destructive layer (B).
［易破壊層（Ｂ）］
易破壊層（Ｂ）は、本発明のラベルを構成する層の中でそれ自体の凝集力が最も弱く、ラベルの基材層（Ａ）を持って引き剥がしたときに、易破壊層（Ｂ）が容易に凝集破壊する。ラベルを剥離する際に易破壊層（Ｂ）の凝集破壊が同層内部で起こり、引き剥がした基材層（Ａ）側と有色接着剤層（Ｃ）側にそれぞれ易破壊層（Ｂ）の分離したものが追従する。そのため本発明のラベルは剥離後に再貼付することができない。
易破壊層（Ｂ）の形成方法には様々な方法があるが、易破壊層（Ｂ）に熱可塑性樹脂ならびに無機微細粉末および有機フィラーの少なくとも一方を含有させることにより、同層（Ｂ）の凝集力を低下させてより安定した剥離性を得ることが可能であり、本発明ではこの方法に従う。

Moreover, the inorganic fine powder and organic filler quoted by the base material layer (A) can be used for the inorganic fine powder and organic filler in an easily breakable layer (B). The inorganic fine powder and the organic filler of the base material layer (A) and the easily breakable layer (B) may be the same or different.
易破壊層（Ｂ）においてその凝集力を小さくする主な要件は、無機微細粉末および有機フィラーの含有量である。易破壊層（Ｂ）における無機微細粉末および有機フィラーの少なくとも一方の含有量は、２０〜７５重量％であることが好ましく、２５〜７０重量％であることがより好ましい。易破壊層（Ｂ）の無機微細粉末および有機フィラーの少なくとも一方の含有量が２０重量％未満では十分な剥離性が得られず、７５重量％を越えては同層（Ｂ）の成形安定性が損なわれる。 The main requirement for reducing the cohesive force in the easily breakable layer (B) is the content of inorganic fine powder and organic filler. The content of at least one of the inorganic fine powder and the organic filler in the easily breakable layer (B) is preferably 20 to 75% by weight, and more preferably 25 to 70% by weight. If the content of at least one of the inorganic fine powder and the organic filler in the easily breakable layer (B) is less than 20% by weight, sufficient peelability cannot be obtained, and if it exceeds 75% by weight, the molding stability of the same layer (B) Is damaged.
また易破壊層（Ｂ）は、二軸延伸されていることが好ましい。無機微細粉末または有機フィラーの少なくとも一方を含有させて延伸成形された易破壊層（Ｂ）の内部には、無機微細粉末または有機フィラーを核とした多数の空孔が形成され、脆性な易破壊層（Ｂ）を得ることができる。また延伸成形により均一な厚みを有する易破壊層（Ｂ）を得る事が可能となる。その結果、易破壊層（Ｂ）は、その凝集力が５〜１５０ｇ／ｃｍ幅であること
が好ましく、１０〜１４０ｇ／ｃｍ幅であることがより好ましい。
易破壊層（Ｂ）の肉厚は、通常０．１〜１０μｍ、好ましくは０．２〜５μｍの範囲である。０．１μｍ未満では均一な膜圧の易破壊層（Ｂ）を形成することが困難となり、その弱い凝集力を発揮できずに安定した剥離性が得にくい傾向となる。逆に１０μｍを越えては剥離性に問題はないが、同層厚み方向の略同位置に剥離応力を集中させづらくなり、剥離力に振れが生じやすくなる。
The easily breakable layer (B) is preferably biaxially stretched. In the easily breakable layer (B) stretched and formed containing at least one of inorganic fine powder or organic filler, a number of pores with inorganic fine powder or organic filler as the core are formed, and brittle easy breakage A layer (B) can be obtained. Further, it becomes possible to obtain an easily breakable layer (B) having a uniform thickness by stretch molding. As a result, the easily breakable layer (B) preferably has a cohesive force of 5 to 150 g / cm width, and more preferably 10 to 140 g / cm width.
The thickness of the easily breakable layer (B) is usually 0.1 to 10 μm, preferably 0.2 to 5 μm. If the thickness is less than 0.1 μm, it becomes difficult to form the easily breakable layer (B) having a uniform film pressure, and the weak cohesive force cannot be exhibited, and stable peelability tends to be hardly obtained. On the contrary, if it exceeds 10 μm, there is no problem in peelability, but it becomes difficult to concentrate the peel stress at substantially the same position in the thickness direction of the same layer, and the peel force tends to be shaken.
［有色接着剤層（Ｃ）］
有色接着剤層（Ｃ）は、本発明のラベルを被着体に接着可能とするものであり、着色剤により着色されており、本発明のラベルにおいて、易破壊層（Ｂ）よりもその凝集力が強く、接着力が強いことを特徴とする。従ってラベルを被着体に貼付した後に、被着体より基材層（Ａ）を引き剥がそうとしたとき、有色接着剤層（Ｃ）内で凝集破壊することなく、また接着面で界面剥離することなく、易破壊層（Ｂ）を効果的に破壊することができる。有色接着剤層（Ｃ）の凝集力、又は接着力が易破壊層（Ｂ）のそれよりも小さい場合は、剥離（凝集破壊）は有色接着剤層（Ｃ）内、又は接着面で進行し、所期の目的は達成できない。
[Colored adhesive layer (C)]
The colored adhesive layer (C) is capable of adhering the label of the present invention to the adherend, and is colored with a colorant. In the label of the present invention, the agglomerated layer is more aggregated than the easily breakable layer (B). It is characterized by strong strength and strong adhesive strength. Therefore, when the substrate layer (A) is peeled off from the adherend after the label has been applied to the adherend, it does not cause cohesive failure in the colored adhesive layer (C), and the interface peels off at the adhesive surface. The easily breakable layer (B) can be effectively destroyed without doing so. When the cohesive strength of the colored adhesive layer (C) or the adhesive strength is smaller than that of the easily breakable layer (B), peeling (cohesive failure) proceeds in the colored adhesive layer (C) or on the adhesive surface. The intended purpose cannot be achieved.
また有色接着剤層（Ｃ）は、易破壊層（Ｂ）上に３０〜９５％の面積割合でパターン状に設けられており、且つそのパターンの最小単位が０．１〜３０５ｍｍのピッチを有していることを特徴としている。面方向にパターン状に設けることで、ラベルが剥離されたことを肉眼で容易に判別することができる。
有色接着剤層（Ｃ）は、所期の目的を達成するために用いる接着剤の凝集力が２０〜１０００ｇ／ｃｍ幅であることが好ましく、２５〜８００ｇ／ｃｍ幅であることがより好ましく、２００〜５００ｇ／ｃｍ幅であることが特に好ましい。有色接着剤層（Ｃ）の凝集力が２０ｇ／ｃｍ幅未満では、強度が不十分で易破壊層（Ｂ）を充分に破壊できずに所期の目的を達成しづらい傾向がある。逆に有色接着剤層（Ｃ）の凝集力が１０００ｇ／ｃｍ幅を超えては、接着力が低下したり、微細なパターンを有する有色接着剤層（Ｃ）を形成することが困難になる傾向がある。
The colored adhesive layer (C) is provided in a pattern with an area ratio of 30 to 95% on the easily breakable layer (B), and the minimum unit of the pattern has a pitch of 0.1 to 305 mm. It is characterized by that. By providing a pattern in the surface direction, it is possible to easily determine with the naked eye that the label has been peeled off.
In the colored adhesive layer (C), the cohesive force of the adhesive used for achieving the intended purpose is preferably 20 to 1000 g / cm width, more preferably 25 to 800 g / cm width, A width of 200 to 500 g / cm is particularly preferable. If the cohesive force of the colored adhesive layer (C) is less than 20 g / cm width, the strength is insufficient and the easily breakable layer (B) cannot be sufficiently broken, and the intended purpose tends to be difficult to achieve. Conversely, if the cohesive force of the colored adhesive layer (C) exceeds 1000 g / cm width, the adhesive force tends to decrease or it becomes difficult to form the colored adhesive layer (C) having a fine pattern. There is.
有色接着剤層（Ｃ）の易破壊層（Ｂ）上における面積割合は、易破壊層（Ｂ）の面積を１００％とした場合、３０〜９５％であり、４０〜９０％が好ましい。
３０％未満では被着体との接着力が不十分であり、また易破壊層（Ｂ）を充分に破壊できずに所期の目的を達成しづらい。逆に９５％を越えては易破壊層（Ｂ）を意図した模様状に剥離できずに面方向全体に破壊してしまう恐れがあり、所期の目的を達成しづらい。
また有色接着剤層（Ｃ）は、易破壊層（Ｂ）上にパターン状に設けられており、且つそのパターンの最小単位が０．１〜３０５ｍｍのピッチを有していることを特徴としている。同ピッチは１〜１５０ｍｍであることが好ましく、１．５〜１００ｍｍであることがより好ましく、２〜３５ｍｍであることが特に好ましい。
ピッチが０．１ｍｍ未満では形成できるパターンが微細になりすぎ、ラベルを剥離した際のパターン剥離の再現性が不十分となり、またパターン形成自体が困難となる傾向がある。逆にピッチが３０５ｍｍを超えては、パターン間の間隔が開きすぎて上記面積割合を満たしづらくなる傾向がある。
The area ratio of the colored adhesive layer (C) on the easily breakable layer (B) is 30 to 95%, preferably 40 to 90% when the area of the easily breakable layer (B) is 100%.
If it is less than 30%, the adhesive force with the adherend is insufficient, and the easily breakable layer (B) cannot be sufficiently broken, and it is difficult to achieve the intended purpose. On the other hand, if it exceeds 95%, the easily breakable layer (B) may not be peeled into the intended pattern and may be destroyed in the entire surface direction, making it difficult to achieve the intended purpose.
The colored adhesive layer (C) is provided in a pattern on the easily breakable layer (B), and the minimum unit of the pattern has a pitch of 0.1 to 305 mm. . The pitch is preferably 1 to 150 mm, more preferably 1.5 to 100 mm, and particularly preferably 2 to 35 mm.
If the pitch is less than 0.1 mm, the pattern that can be formed becomes too fine, the reproducibility of the pattern peeling when the label is peeled off, and the pattern formation itself tends to be difficult. On the contrary, if the pitch exceeds 305 mm, there is a tendency that an interval between patterns is too wide to satisfy the above-mentioned area ratio.

本発明のラベルは易破壊層（Ｂ）が少なくとも一軸方向に延伸されていることが好ましい。これを達成するためには基材層（Ａ）および易破壊層（Ｂ）は、積層して積層フィルムとした後に、これを少なくとも１軸方向に延伸して各層を延伸することが好ましい。本発明の易破壊層（Ｂ）は脆弱で強度が低く、通常肉厚も薄い為、易破壊層（Ｂ）単層での延伸成形は極めて困難である。基材層（Ａ）は支持体として易破壊層（Ｂ）を積層した後にこれを延伸することにより、易破壊層（Ｂ）の延伸成形が容易となる。
[Stretching]
In the label of the present invention, the easily breakable layer (B) is preferably stretched at least in a uniaxial direction. In order to achieve this, the base material layer (A) and the easily breakable layer (B) are preferably laminated to form a laminated film, and then stretched in at least a uniaxial direction to stretch each layer. Since the easily breakable layer (B) of the present invention is fragile and low in strength, and usually has a small thickness, it is extremely difficult to stretch-mold the easily breakable layer (B) as a single layer. The base layer (A) is easily stretched and formed by laminating the easily breakable layer (B) as a support and then stretching the easily breakable layer (B).
本発明の易破壊層（Ｂ）は、延伸を行うことにより内部への空孔形成、薄膜化や厚みの均一化が容易となる。延伸方法としては、キャスト成形フィルムを延伸する場合は、ロール群の周速差を利用した縦延伸、テンターオーブンを使用した横延伸、圧延、テンターオーブンとリニアモーターの組み合わせによる同時二軸延伸、テンターオーブンとパンタグラフの組み合わせによる同時二軸延伸、インフレーション成形法による同時二軸延伸などを挙げることができる。
延伸倍率は特に限定されず、用いる熱可塑性樹脂の特性等を考慮して適宜決定する。例えば、熱可塑性樹脂としてプロピレン単独重合体ないしはその共重合体を使用する時には一方向に延伸する場合は約１．２〜１２倍、好ましくは２〜１０倍であり、二軸延伸の場合には面積倍率で１．５〜６０倍、好ましくは４〜５０倍である。その他の熱可塑性樹脂を使用する時には一方向に延伸する場合は１．２〜１０倍、好ましくは２〜５倍であり、二軸延伸の場合には面積倍率で１．５〜２０倍、好ましくは４〜１２倍である。
The easily breakable layer (B) of the present invention can be easily stretched to form pores, thin film and uniform thickness. As the stretching method, in the case of stretching a cast film, longitudinal stretching using the peripheral speed difference of the roll group, lateral stretching using a tenter oven, rolling, simultaneous biaxial stretching using a combination of a tenter oven and a linear motor, tenter Examples thereof include simultaneous biaxial stretching by a combination of an oven and a pantograph, and simultaneous biaxial stretching by an inflation molding method.
The draw ratio is not particularly limited, and is appropriately determined in consideration of the characteristics of the thermoplastic resin used. For example, when a propylene homopolymer or a copolymer thereof is used as a thermoplastic resin, it is about 1.2 to 12 times, preferably 2 to 10 times when stretched in one direction. The area magnification is 1.5 to 60 times, preferably 4 to 50 times. When using other thermoplastic resins, it is 1.2 to 10 times, preferably 2 to 5 times when stretched in one direction, and preferably 1.5 to 20 times by area magnification in the case of biaxial stretching. Is 4 to 12 times.
延伸時の温度は、用いる熱可塑性樹脂のガラス転移点温度以上から結晶部の融点以下の熱可塑性樹脂に好適な公知の温度範囲内で行うことができる。具体的には、熱可塑性樹脂がプロピレン単独重合体（融点１５５〜１６７℃）の場合は１００〜１６４℃、高密度ポリエチレン（融点１２１〜１３４℃）の場合は７０〜１３３℃であり融点より１〜７０℃低い温度である。また、ポリエチレンテレフタレート（融点２４６〜２５２℃）では結晶化が急激に進まない温度を選択する。また、延伸時のライン速度は２０〜３５０ｍ／分であるのが好ましい。 The temperature at the time of stretching can be performed within a known temperature range suitable for a thermoplastic resin having a temperature not lower than the glass transition temperature of the thermoplastic resin used and not higher than the melting point of the crystal part. Specifically, when the thermoplastic resin is a propylene homopolymer (melting point 155 to 167 ° C.), it is 100 to 164 ° C., and when it is a high density polyethylene (melting point 121 to 134 ° C.), it is 70 to 133 ° C. ˜70 ° C. lower temperature. For polyethylene terephthalate (melting point: 246 to 252 ° C.), a temperature at which crystallization does not advance rapidly is selected. The line speed during stretching is preferably 20 to 350 m / min.

[Evaluation technique]
[Cohesive strength]
In the present invention, the strength against peeling of each of the base material layer (A), the easily breakable layer (B), and the colored adhesive layer (C) constituting the label is organized by cohesive force. The cohesive strength was defined as the peel strength obtained from the peel strength test. Specifically, the peel strength of the base material layer (A) and the easily breakable layer (B) is obtained by the method described later, and the peel strength of the colored adhesive layer (C) is JIS-K-6854-2: 1999. The peel strength was determined according to the peel adhesion strength test method by 180 degree peeling. The peel strength (cohesive force) of the colored adhesive layer (C) is preferably 20 to 1000 g / cm width, and more preferably 25 to 800 g / cm width.
［基材層（Ａ）の剥離強度］
厚み１ｍｍのアルミ板に接着剤（東洋モートン社製、商品名「ＴＭ５９５」および「ＣＡＴ５６」の標準混合物）を２５ｇ／ｍ2となるように、且つ端部の約３０ｍｍ幅は未塗工とし把持部（つかみしろ）を形成するように塗工し、これと積層フィルムの基材層（Ａ）面を接するように重ね合わせ、圧着し、これを恒温室（温度２０℃、相対湿度６５％）に１週間保管した後、これを幅１０ｍｍ、長さ３００ｍｍに切り取り、引張試験機（（株）島津製作所製、商品名：オートグラフＡＧＳ−５ＫＮＤ）を使用し、引張速度３００ｍｍ／分にて、アルミ板側と積層フィルム側それぞれの把持部を１８０゜の角度で剥離させ、基材層（Ａ）の剥離が安定している時の応力を、または基材層（Ａ）の凝集力が非常に強く安定して剥離せずに破断してしまう場合には破断直前の最大応力を、ロードセルにより測定する。
[Peel strength of base material layer (A)]
Glue adhesive (standard mixture of trade name “TM595” and “CAT56”, manufactured by Toyo Morton Co., Ltd.), 25 mm / m 2, to an aluminum plate with a thickness of 1 mm, and the end of about 30 mm width is uncoated Is applied so as to form a part (grip margin), and this is laminated so that the surface of the base film layer (A) of the laminated film is in contact with each other, followed by pressure bonding, and this is temperature-controlled (temperature 20 ° C., relative humidity 65%) After being stored for 1 week, this was cut into a width of 10 mm and a length of 300 mm, and a tensile tester (manufactured by Shimadzu Corporation, trade name: Autograph AGS-5KND) was used at a tensile speed of 300 mm / min. The gripping part on the aluminum plate side and the laminated film side is peeled at an angle of 180 °, and the stress when the peeling of the base material layer (A) is stable, or the cohesive force of the base material layer (A) is very It is strong and stable and breaks without peeling The maximum stress of just before break when put away, is measured by the load cell.
基材層（Ａ）の剥離強度（凝集力）は５０〜１５０００ｇ／ｃｍ幅であることが好ましく、より好ましくは１００〜１２０００ｇ／ｃｍ幅である。剥離強度が５０ｇ／ｃｍ幅未満では、易破壊層（Ｂ）や有色接着剤層（Ｃ）の凝集力に負けてラベルの剥離がスムーズに進行しづらい。１５０００ｇ／ｃｍ幅を超えてはラベルとして機能上問題はないが、本発明の材料選定上、同様の基材層（Ａ）は得にくい。
基材層（Ａ）が多層構造である場合は、易破壊層（Ｂ）と接する層を層（Ａ１）とし、これの剥離強度を測定した。具体的には同様の樹脂組成物や成形条件を用いて層（Ａ１）と易破壊層（Ｂ）の２層構造からなる積層フィルムを別途成形して、上記手法により測定をした。
The peel strength (cohesive force) of the base material layer (A) is preferably 50 to 15000 g / cm width, more preferably 100 to 12000 g / cm width. When the peel strength is less than 50 g / cm width, it is difficult for the label to smoothly peel off due to the cohesive force of the easily breakable layer (B) and the colored adhesive layer (C). If the width exceeds 15000 g / cm, there is no problem in terms of function as a label, but it is difficult to obtain a similar base material layer (A) in selecting the material of the present invention.
When the base material layer (A) has a multilayer structure, the layer in contact with the easily breakable layer (B) was defined as the layer (A1), and the peel strength thereof was measured. Specifically, a laminated film having a two-layer structure of a layer (A1) and an easily breakable layer (B) was separately molded using the same resin composition and molding conditions, and measured by the above method.
［易破壊層（Ｂ）の剥離強度］
積層フィルムを恒温室（温度２０℃、相対湿度６５％）に１２時間保管した後、易破壊層（Ｂ）面に粘着テープ（ニチバン（株）製、商品名：セロテープ ＣＴ−１８）を貼着し、これを幅１０ｍｍ、長さ３００ｍｍに切り取り、その一端の粘着テープを手で約３０ｍｍ剥がして粘着テープ側と積層フィルム側の把持部を形成する。引張試験機（（株）島津製作所製、商品名：オートグラフＡＧＳ−５ＫＮＤ）を使用し、引張速度３００ｍｍ／分にて、それぞれの把持部を１８０゜の角度で剥離させ、易破壊層（Ｂ）の剥離が安定している時の応力をロードセルにより測定する。
易破壊層（Ｂ）の剥離強度（凝集力）は５〜１５０ｇ／ｃｍ幅であることが好ましく、より好ましくは１０〜１４０ｇ／ｃｍ幅である。剥離強度が５ｇ／ｃｍ幅未満では、印刷、印字、断裁等の二次加工時において簡単に剥離が生じる可能性があり、二次加工性に問題が生じる。１５０ｇ／ｃｍ幅を超えては、易破壊層（Ｂ）が剥離しないか、剥離に要する応力を高くする必要があり実用的でない。
[Peel strength of easily breakable layer (B)]
After the laminated film is stored in a temperature-controlled room (temperature 20 ° C., relative humidity 65%) for 12 hours, an adhesive tape (manufactured by Nichiban Co., Ltd., trade name: cello tape CT-18) is attached to the surface of the easily breakable layer (B). Then, this is cut into a width of 10 mm and a length of 300 mm, and the adhesive tape at one end thereof is peeled off by about 30 mm by hand to form a gripping portion on the adhesive tape side and the laminated film side. Using a tensile tester (manufactured by Shimadzu Corporation, trade name: Autograph AGS-5KND), each gripping part was peeled off at an angle of 180 ° at a pulling speed of 300 mm / min, and an easily breakable layer (B ) Is measured with a load cell when the peeling is stable.
The peel strength (cohesive force) of the easily breakable layer (B) is preferably 5 to 150 g / cm width, more preferably 10 to 140 g / cm width. If the peel strength is less than 5 g / cm width, peeling may occur easily during secondary processing such as printing, printing, cutting, etc., and a problem arises in secondary workability. If the width exceeds 150 g / cm, it is not practical because the easily breakable layer (B) does not peel or it is necessary to increase the stress required for peeling.
［有色接着剤層（Ｃ）の面積割合］
本発明のラベル上にパターン状に形成されている有色接着剤層（Ｃ）のラベル面積に対する面積割合およびパターン間のピッチは、その創作時に、所望の値で規定することができるが、以下の評価技法により確認することもできる。

Next, binarization processing of the observation image is performed by the image processing analysis apparatus, and the colored area with respect to the entire image area is analyzed as an area ratio with respect to the label area of the colored adhesive layer (C), and is obtained as a percentage. When the colorant to be used is a white pigment or the like and the color difference from the label is small, the surface of the obtained label on the side of the colored adhesive layer (C) is superimposed on a transparent glass plate with a flat surface. After the 2 kg roller is reciprocated twice and stuck on the top, the label is peeled off, and the easily breakable layer (B) and the colored adhesive layer (C) remaining on the glass plate are observed by the above technique.
