Description
本発明は、トイレットペーパー及びキッチンタオル等のロール状ペーパー、ロール状ペーパーに塗布されるロール状ペーパー用接着剤、特にロール状ペーパーの巻き始めに塗布される接着剤（いわゆるピックアップ剤）に関する。 The present invention relates to roll paper such as toilet paper and kitchen towel, an adhesive for roll paper applied to the roll paper, particularly an adhesive (so-called pickup agent) applied to the beginning of winding of the roll paper.
ロール状ペーパーとは、例えば、キッチンペーパー、ペーパーウェス、ラッピングペーパー、トイレットペーパー及びペーパータオル等の紙がロール状に巻かれた紙製品をいい、有芯型と無芯型がある。有芯型のロール状ペーパーは、筒芯（紙管）に紙を緩く巻き付け、紙を所望の長さと外径を有するように巻き取ることにより製造されている。無芯型のロール状ペーパーは、細い巻芯（巻軸）に紙を緩く巻付け、次いで固く巻き付けて所望の長さと外径を有する製品とし、その後巻芯を抜いて製造されるか、有芯型の筒芯と同径の巻芯に紙を固く巻き付けて所望の長さと外径を有する製品とし、その後、巻芯を抜いて製造されている。 The roll paper refers to, for example, a paper product in which paper such as kitchen paper, paper waste, wrapping paper, toilet paper, and paper towel is wound into a roll shape, and includes a core type and a coreless type. The cored roll paper is manufactured by loosely winding paper around a cylindrical core (paper tube) and winding the paper to have a desired length and outer diameter. Uncore type roll paper is manufactured by winding the paper loosely around a thin core (winding shaft) and then winding it tightly to make a product with the desired length and outer diameter, and then removing the core or It is manufactured by winding paper tightly around a core having the same diameter as that of the core cylinder, to obtain a product having a desired length and outer diameter, and then removing the core.
ロール状ペーパーを製造する際、有芯型、無芯型を問わず、紙を巻き始める部分に、特殊な接着剤、いわゆるピックアップ剤が塗布され、芯（例えば、筒芯及び巻芯等であり、特に、紙管）とペーパーが接着される。 When manufacturing roll paper, regardless of whether it is a cored type or a coreless type, a special adhesive, so-called pickup agent, is applied to the part where the paper starts to be rolled, and a core (for example, a cylindrical core and a core) In particular, the paper tube) and the paper are bonded.
ピックアップ剤には、下記の性能が要求される：１）ピックアップ剤は芯に塗布された後、乾燥前の湿った状態で、芯と、ロール状に巻かれるペーパーを迅速に接着できること；及び、２）ピックアップ剤の乾燥後、接着されたペーパーを芯から簡単に剥離できること。従って、ピックアップ剤には、湿った状態での接着性（以下、「初期接着性」ともいう）及び乾燥後の剥離性（以下、単に「剥離性」ともいう）の双方に優れることが要求される。 The following performance is required for the pickup agent: 1) The pickup agent can be quickly bonded to the core and the paper wound in a roll shape in a wet state before drying after being applied to the core; and 2) After the pickup agent is dried, the adhered paper can be easily peeled off from the core. Accordingly, the pickup agent is required to be excellent in both adhesiveness in a wet state (hereinafter also referred to as “initial adhesiveness”) and peelability after drying (hereinafter also simply referred to as “peelability”). The
水、ポリビニルアルコール、エチルセルロース、ポリ酢酸ビニル、アクリル樹脂等を主成分とするピックアップ剤が公知である。しかし、これらのピックアップ剤は、初期接着性が高すぎるため、剥離性が不十分であるという問題がある。そこで、ピックアップ剤の剥離性を向上させることを目的として、ピックアップ剤に剥離調整剤を添加する方法が知られている（例えば、特許文献１及び特許文献２参照）。 A pickup agent mainly composed of water, polyvinyl alcohol, ethyl cellulose, polyvinyl acetate, acrylic resin or the like is known. However, these pick-up agents have a problem that the initial adhesiveness is too high and the peelability is insufficient. Therefore, a method of adding a release adjusting agent to the pickup agent is known for the purpose of improving the peelability of the pickup agent (see, for example, Patent Document 1 and Patent Document 2).
例えば、特許文献１は、でんぷん等の糖類を主成分とする糊に、剥離調整剤として脂肪酸エステルや脂肪酸アミドが添加されたピックアップ剤を開示する（特許文献１請求項１及び２、及び実施例等参照）。また、特許文献２は、剥離調整剤としてポリアルキレングリコールを用いることを開示する（特許文献２請求項１及び２、及び実施例参照）。 For example, Patent Document 1 discloses a pick-up agent in which a fatty acid ester or a fatty acid amide is added as a release adjusting agent to a paste such as starch as a main component (Patent Document 1, Claims 1 and 2 and Examples). Etc.). Moreover, patent document 2 discloses using polyalkylene glycol as a peeling regulator (refer patent document 2 claim 1 and 2 and an Example).
これらの特許文献１及び２に開示されたピックアップ剤は、剥離調整剤を含むので、剥離性に優れるため、芯からペーパーを容易に剥がすことができるが、初期接着性が不十分である。初期接着性に乏しいピックアップ剤をロール状ペーパーの巻き始めの箇所に塗布しても、湿った状態での接着力が低いため、芯とペーパーとを接着（即ち、ピックアップ）させることができないという問題がある。
ピックアップ剤の初期接着性と剥離性とのバランスをとるため、剥離調整剤の添加量を制御すると、ロール状ペーパーの塗工面がべたつき、剥離性が低下することがあった。
Since the pick-up agents disclosed in these Patent Documents 1 and 2 contain a release adjusting agent, they are excellent in releasability, so that the paper can be easily peeled off from the core, but the initial adhesiveness is insufficient. Even if a pickup agent with poor initial adhesiveness is applied to the beginning of the roll paper roll, the adhesive strength in the wet state is low, so the core and paper cannot be bonded (ie, picked up). There is.
In order to balance the initial adhesiveness and peelability of the pickup agent, when the amount of the release modifier added is controlled, the coated surface of the roll paper may become sticky and the peelability may be reduced.
本発明は、このような事情を鑑みなされたものであり、初期接着性が高く、塗工面をべたつかせることなく紙を容易に剥離させるロール状ペーパー用接着剤（特に、ピックアップ剤）、及びそのロール状ペーパー用接着剤が塗布されたロール状ペーパーを提供することを目的とする。 The present invention has been made in view of such circumstances, and has a high initial adhesiveness, and an adhesive for roll paper (especially a pick-up agent) that easily peels the paper without sticking the coated surface, and its It aims at providing the roll-shaped paper with which the adhesive agent for roll-shaped paper was apply | coated.
そこで、本研究者らは、鋭意研究を続けた結果、グルコースを含有する糖類に、特定の水性高分子及び特定の化合物を添加した接着剤は、「べたつき」を生じず、かつ初期接着性及び剥離性に優れ、特に、ピックアップ剤として有用であることを見出し、本発明を完成させるに至った。 Therefore, as a result of intensive research, the present researchers have found that an adhesive obtained by adding a specific aqueous polymer and a specific compound to a saccharide containing glucose does not cause “stickiness” and has an initial adhesive property and The present inventors have found that it is excellent in releasability and is particularly useful as a pickup agent, and has completed the present invention.

After leaving at room temperature (23 ° C.) for 24 hours, the paper tube and the 2-ply-toilet roll paper were peeled off, and then the tack level of the surface coated with the adhesive was evaluated by a finger-corrosion test.
(Evaluation criteria)
◎: No stickiness ◯: Little stickiness △: Some stickiness ×: Stickiness
実施例１〜１７及び比較例１〜９のロール状ペーパー用接着剤の剥離性試験、初期接着性試験、べたつき試験の評価結果を、下記表３及び４にまとめた。 Tables 3 and 4 below show the evaluation results of the peelability test, the initial adhesion test, and the stickiness test of the adhesives for roll paper of Examples 1 to 17 and Comparative Examples 1 to 9.
表１及び３に示されるように、実施例１〜１７の接着剤は、剥離性及び初期接着性に優れ、べたつきも生じなかった。これらの性能をバランス良く維持する接着剤は、ロール状ペーパー用接着剤、特にピックアップ剤として有効である。
比較例１〜９の接着剤は、表２及び４に示されるように、剥離性、初期接着性、べたつきのいずれかに問題がある。
As shown in Tables 1 and 3, the adhesives of Examples 1 to 17 were excellent in peelability and initial adhesiveness, and did not cause stickiness. An adhesive that maintains these performances in a well-balanced manner is effective as an adhesive for rolled paper, particularly as a pickup agent.
As shown in Tables 2 and 4, the adhesives of Comparative Examples 1 to 9 have problems in any of peelability, initial adhesiveness, and stickiness.
比較例１〜３の接着剤は、成分（Ｂ）を含まないので、初期接着性が低下している。比較例４〜８の接着剤は、グルコース成分である（Ａ−１）又は（Ａ−２）を含まないので、実施例の接着剤と比較すると、剥離性に劣る。比較例４及び５は、糖類として（Ａ’−３）デキストリンを含むが、グルコースを含まないので、剥離性が低下している。比較例６〜７は、糖類として（Ａ’−４）カルボキシメチルセルロースや（Ａ’−５）メチルセルロースを含むが、グルコースを含まず、更に剥離性や初期接着性が低下している。比較例８は、ポリビニルアルコールを含むが、糖類を全く含まず、剥離性や初期接着性に乏しい。比較例９は、成分（Ｃ）を含まないので、べたつきを生じる。 Since the adhesives of Comparative Examples 1 to 3 do not contain the component (B), the initial adhesiveness is lowered. Since the adhesives of Comparative Examples 4 to 8 do not contain (A-1) or (A-2) which is a glucose component, they are inferior in peelability as compared with the adhesives of Examples. Comparative Examples 4 and 5 contain (A′-3) dextrin as a saccharide, but do not contain glucose, so that the peelability is reduced. Comparative Examples 6 to 7 contain (A′-4) carboxymethyl cellulose and (A′-5) methyl cellulose as saccharides, but do not contain glucose, and the peelability and initial adhesiveness are further reduced. Although the comparative example 8 contains polyvinyl alcohol, it does not contain saccharides at all and has poor peelability and initial adhesiveness. Since Comparative Example 9 does not contain the component (C), stickiness is generated.
これらの結果から、ロール状ペーパー用接着剤として優れた性能を持つために、３成分（（Ａ）〜（Ｃ））を必須成分とすることが明らかとなった。 From these results, it became clear that the three components ((A) to (C)) are essential components in order to have excellent performance as an adhesive for rolled paper.
本発明は、ロール状ペーパー用接着剤、及びそのロール状ペーパーが塗布されたロール状ペーパーを提供できる。本発明に係るロール状ペーパーは、特にピックアップ剤として有用である。 The present invention can provide an adhesive for roll-shaped paper and a roll-shaped paper coated with the roll-shaped paper. The roll paper according to the present invention is particularly useful as a pickup agent.
