201132301 六、發明說明： 【發明所屬之技術領域】 本發明係有關一種附有濾嘴之香菸的濾嘴之包捲作 為最外層的外層紙(tip paper)，以及具有該外層紙的附有濾 嘴之香於。 【先前技術】 附有濾嘴之香菸係使菸條與濾嘴緊密對齊，以外層紙 將濾嘴之外周面全部以及緊密對齊部附近的菸條之外周面 部包捲並使之一體化者。 在抽吸附有濾嘴之香菸時，如唾液附著在外層紙、或 牙齒與嘴唇對外層紙造成摩擦時，位於濾嘴端部之外層紙 表面部分在受捻狀態下剝離，發生所謂的紙層剝離。 一直以來，為了避免上述外層紙之問題，一般係施行 賦予耐水性之技術。而此技術係在含紙衆之底織物表面以 印刷塗佈而形成疏水性塗劑（含有作為疏水性物質之确化 纖維)層之方法。如此技術可因應疏水性塗劑層之基重而發 揮一定的耐水效果。然而，僅形成有以硝化纖維之基重 (basis weight)計為0.8gsm左右之疏水性塗劑層的外層紙之 而才水效果並不足。事實上，會因财水性不足而發生外層紙 的紙層剝離。 因此，僅形成以往之一般技術的簡易之疏水性塗劑 層，作為外層紙所需耐水性之機能並不足，由耐水性之觀 點而言，進而尋求高品質之外層紙。 基於上述情況，在日本特開平7-316996號公報中揭 3 321929 201132301 示一種菸條捲紙，係在原紙製造時，添加如烷基烯酮二聚 物（AKD)之上衆劑（sizing agent)，再於添加有上漿劑之底織 物表面塗佈上述上漿劑而經更提高表面上漿度（sizing degree)並賦予耐水性。然而，上漿劑之效果僅為延緩水對 底織物的滲透，而非為本質上強化底織物之紙漿纖維間的 結合強度者，僅不過與以往一般技術之疏水性物質層的形 成之機能相同。因此，即使將如此捲紙適用於外層紙，耐 水性效果依然不足。而且，上述捲紙對外層紙之適用係， 外層紙之極端的上漿度之增加會明顯地損及在附有濾嘴之 香菸之製造時的上漿適性。 在曰本特開2000-64192號公報中揭示一種多孔性塞 包裝紙，係將濾嘴直接包覆之多孔性濾嘴包裝紙，其中， 加入實質上含有烷基烯酮二聚物之濕潤強度強化劑，且塗 佈含有聚乙烯醇之上漿組成物而增大濕潤抗張強度。惟多 孔性濾嘴包裝紙與菸條和濾嘴經一體化之外層紙不同，如 將上述上漿組成物之塗佈適用於外層紙表面，在附有濾嘴 之香菸之製造時，將明顯地損及上漿適性。 【發明内容】 本發明之目的係提供一種外層紙以及具有該外層紙 之高品質的附有濾嘴之香菸，上述外層紙係在使用於附有 濾嘴之香菸時呈現優異的耐水性，可有效地抑制甚至防止 吸菸時之唾液的附著、或因牙齒與嘴唇之摩擦所引起的紙 層剝離，且印墨之固定性優異者。 本發明之第1態樣提供一種外層紙，係含有紙漿與作 4 321929 201132301 為填料之碳酸鈣，相對於上述紙漿以及上述碳酸鈣之總基 重，上述碳酸鈣量至少有ίο重量％，並且進一步在含有濕 潤紙力增強劑（strengthening agent for wet paper)之底織物 表面形成疏水性塗劑層者。 本發明之第2態樣提供一種附有濾嘴之香菸，係具有 上述外層紙者。 【實施方式】 [用以實施發明之型態] 以下，詳細說明本發明之實施形態的外層紙及附有濾 嘴之香菸。 實施形態之外層紙係含有紙漿與作為填料之碳酸 鈣，相對於上述紙漿以及上述碳酸鈣之總基重，上述碳酸 鈣量至少有10重量％，並且進一步在含有濕潤紙力增強劑 之底織物表面形成疏水性塗劑層者。此處之π底織物表面” 係指在適用於附有濾嘴之香菸時，為與在包捲菸條之一部 分以及整個濾嘴時鄰接該等之面相反側之面的全部。 本發明者等依據下述知識與見解而發現上述之外層 紙。 (1)外層紙之耐水化 由含有基重37gsm之紙漿及濕潤紙力增強劑（聚醯胺-表氯醇：PAE)的底織物所構成，且變更PAE相對於紙漿之 添加量（最大值：1.5重量％)，得到外層紙。依下述方法測 定在將所得各外層紙在濕潤時之抗張強度。將其結果示於 第1圖。 5 321929 201132301 (濕潤時之抗張強度） 將外層紙裁切成15mm寬度之試驗片，取其長^# 之中央部12mm範圍浸潰於水槽中。水充分滲透後1〇八向 後，將試驗片從水槽中取出。然後，將多餘的水分擦 測定抗張強度。抗張強度之測定係使用定速伸長型彳1 &並 驗機（Tensilon抗張試驗機）。將上述試驗片之未沾、違張4 方向之兩端固定在測定器的可動式把手（kn〇b)後，勺長度 部位移動，於固定速度下電性檢測試驗片將要斷

表面形成以硝化纖維(NC)基重計為0.4gSrn之含硝化纖維 (NC)的疏水性塗劑層之外層紙。 由第2圖可明暸，隨著濕潤紙力增強劑(PAE)量之增 加，使對捻狀之紙層剝離的濕潤耐摩擦次數增加。然而， 對紙層剝離之外層紙的耐水性係與習知技術之僅形成NC 層的外層紙之程度相同。 (3)濕潤紙力增強劑的添加與疏水性塗劑層的形成之組合 效果 如上述(2)所述，對含有濕潤紙力增強劑之外層紙的紙 7 321929 201132301 層剝離之效果’與藉由單純地印刷塗佈而形成疏水性塗劑 層幾乎相等，未必為超出習知技術。 由如此之情況’本發明者對於經由組合濕潤紙力增強 劑（PA E)的添加與疏水性塗劑層的形成而提高機能者進行 檢討。 亦即，分別準備：相對於紙漿量含有1.0重量％之濕 潤紙力增強劑（PAE)的尺寸20mmx250mm之外層紙（比較 樣品1)、表面以基重0.5gsm(硝化纖維之基重：0.4 gsm) 形成含硝化纖維之疏水性塗劑層的相同尺寸（2〇tnmx 250mm)之外層紙（比較樣品2)、以及相對於紙漿量含有i.o 重量％之濕潤紙力增強劑（PAE)且表面以基重0.5gSm(硝化 纖維之基重：0.4 gsm)形成含硝化纖維之疏水性塗劑層的 相同尺寸（20mmx250mm)之外層紙(試驗樣品丨）。相對於該 等樣品’進行與上述(2)相同之濕潤耐摩擦試驗並進行耐水 評估。將其結果示於第3圖。同時，第3圖之加成效果（預 測）係举純地將比較樣品1、2之濕潤耐摩擦次數合計而得 的結果。 分別準備：相對於紙聚量含有L0重量％之濕潤紙力 增強劑（PAE)的尺寸20mmx250mm之外層紙（比較樣品 3)、表面以基重l.Ogsm(硝化纖維之基重：〇 8gsm)形成含 硝化纖維之疏水性塗劑層的外層紙（比較樣品4 )、以及相對 於紙漿量含有1.0重量％之濕潤紙力增強劑（PAE)且表面以 基重l.Ogsm(硝化纖維之基重：〇.8 gSm)形成含硝化纖維之 疏水性塗劑層的外層紙（试驗樣σσ 2)。相對於該等樣σ，進 321929 8 201132301 行與上述(2)相同之濕潤耐摩擦試驗並進行耐水評估。將其 結果示於第4圖。同時，第4圖之加成效果（預測）係單純 地將比較樣品3、4之濕潤耐摩擦次數合計而得的結果。 由第3圖可明瞭，在濕潤時加上摩擦之評估模型中， 組合濕潤紙力増強劑（PAE)的添加與疏水性塗劑層的形成 之5式驗樣品1 ’其濕潤耐摩擦次數遠超出僅有濕潤紙力增 強劑（PAE)的添加之比較例1與僅有疏水性塗劑層的形成 之比較例2的濕潤耐摩擦次數之合計（預測），確認對外層 紙之紙層剝離的财水效果加乘地增幅。 由第4圖可明瞭，即使疏水性塗劑層之硝化纖維基重 成為5式驗樣品1的2倍之試驗樣品2，其濕潤耐摩擦次數 遠超出僅濕潤紙力增強劑的含有之比較例3與僅有疏水性 塗劑層的形成（硝化纖維基重：2倍）之比較例4的濕潤耐摩 擦次數之總和（預測），確認對外層紙之紙層剝離的耐水效 果同樣地為加乘地增幅。 (4)由濕潤紙力增強劑的添加與疏水性塗劑層的塗佈之組 合而得之加乘效應的理論性考察 為了理論性考察加乘效應而分別準備：相對於紙漿量 含有1.0重量％之濕潤紙力增強劑（PAE)的尺寸15mmx 2G〇mm之外層紙（比較樣品1)、形成以硝化纖維基重計為 的疏水性塗劑層的相同尺寸（i5mmx200mm)之外層 乾（比較樣品2)、以及相對於紙漿量含有1.〇重量％之濕潤 纟氏力增強劑（PAE)且形成以硝化纖維基重計為〇.4gsm的疏 水性塗劑層的相同尺寸之外層紙(試驗樣品1)後，施行更高 9 321929 201132301 精度Μ水試驗。μ ’使各樣品保持在固定加重 (10N/15mm)之張力的狀態，在表面側將iGQ#L之水在寬 度方向散佈成條狀後，測定張力的經時變化。將其結果示 於第5圖。另外，笛ς㈤丄 、 圖中’將抗張強度低於4.0N/15mm :之區域作為紙層制離發生之區域。第$圖中，a係僅 塗μ ^^樣⑽1的添加之評估曲線、b係僅有疏水性 荠^、曰艿/、之比較樣品2之評估曲線、c係組合PA£的

與疏水性塗劑層的形成之组合時，成為至剝離發生的 侧5咖以下之時間遠超出㈣之時間。由此事實而可理 解，至剝離發生之時間的延長化效果為切之加乘效應。 此雖為推淪，然濕潤紙力增強劑的含有與疏水性塗劑 層的形成之組合，在理論上:,濕濁紙力增強劑(pA幻之附著 並不充分’應可認為是耐水化微弱之紙衆纖維的結合部位 絰疏水性塗劑保護而使疏水性塗劑之潛在的耐水性 強之故。 曰 另外，在上述之試驗結果中出現比濕潤耐摩擦試驗結 321929 ：(1 201132301 果更顯著的加乘效應。可認為因濕潤耐摩擦試驗施加荷量 而強力摩擦，而與保持固定加重之張力的上述試驗相比， 係由負荷極高的試驗而成者。 另外，外層紙中所含濕潤紙力增強劑多少會阻礙印墨 的固定性。例如：在外層紙上施行軟木印刷時，印墨顏料 易於脫落且在印刷品質上容易引起墨蠕動（ink mottling)。 由此，本發明者等藉由使作為填料之碳酸鈣，相對於 紙漿以及碳酸鈣之總基重至少含有10重量％者，即可改善 印墨之固定性。 因此，如依實施形態，因藉由組合上述之濕潤紙力增 強劑的含有與疏水性塗劑層的形成而得之加乘效應以及藉 由含有作為填料之碳酸鈣，而在使用在附有濾嘴之香菸時 顯示優異之耐水性，可有效地抑制甚至防止吸菸時之唾液 的附著、或因牙齒與嘴唇之摩擦所引起的紙層剝離，更且 能以含有上述碳酸鈣而補償因濕潤紙力增強劑的添加所引 起的印墨固定性之低下，而得到改善印墨固定性之外層紙。 另外，實施形態之外層紙係依上述優異之耐水性而使 用在附有濾嘴之香菸時，可確認位於濾嘴前端之處的破 損；在開孔部位的破損、斷裂；在菸條與濾嘴交界之黑線 的破損、斷裂；防止外層紙附著於嘴唇（提高離唇機能）。 底織物中所含的紙漿只要為一般外層紙所使用者而 可為任意之物，其例可列舉如：分類為L材（闊葉樹）、N 材（針葉樹）之木材紙漿；蔗渣、亞麻、麻等非木材紙漿； 單純地將木材碾磨而得之機械紙漿；經化學處理抽出而得 12 321929 201132301 之化學紙漿。 作為底織物中所含的填料之碳酸鈣，相對於紙漿以及 碳酸:i弓之總基重，至少含有10重量％。碳酸4弓之含量未達 • 10重量％時，難以謀求外層紙之印墨固定性改善。較佳者 係相對於紙漿以及碳酸鈣之總基重，碳酸鈣之含量在10 重量％以上30重量％以下，以20重量％以上30重量％以 下為佳。另外，作為底織物中之填料的氧化鈦，相對於紙 漿、碳酸鈣以及氧化鈦之總基重，以含有20重量％以下者 為容許範圍。 1 底織物中所含的濕潤紙力增強劑，只要為具有濕潤紙 力機能者而可為任意之物，.其例可列舉如：聚醯胺-表氯醇 (PAE)、聚乙亞胺、環氧化聚驢胺、聚丙烯醯胺。特另以聚 醯胺-表氯醇為佳。 相對於底織物中所含的紙漿，期望濕潤紙力增強劑之 含量為2.0重量％以下，以0.5重量％以上2.0重量％以下 為佳，更以0.8重量％以上1.2重量％以下為最佳。 疏水性塗劑係以含有作為疏水性物質的硝化纖維(NC) 者為佳。尤其是，疏水性塗劑除了 NC之外，宜含有塑化 劑以及樹脂成分。例如：疏水性塗劑宜為含有NC以及適 於凹版印刷之顏料的有色之疏水性印墨。 含有硝化纖維之疏水性塗劑層係在底織物表面以硝 化纖維基重計為O.lgsm以上l.Ogsm以下所形成者，宜為 以硝化纖維基重計為0.2gsm以上0.8gsm以下所形成者。 接著，說明實施形態之附有濾嘴之香菸。 13 321929 201132301 實施形態之附有濾嘴之香菸係具有上述含優異耐水 性之外層紙者。 參照第6圖詳加說明具體的附有濾嘴之香菸。附有濾

Description of the Invention: [Technical Field] The present invention relates to a tip paper of a filter of a filter-attached cigarette as an outermost layer, and a filter having the outer layer of paper The fragrance of the mouth. [Prior Art] A cigarette with a filter is used to closely align the tobacco rod with the filter, and the outer layer paper wraps and integrates the outer peripheral surface of the filter and the outer peripheral portion of the tobacco rod in the vicinity of the closely aligned portion. When smoking a cigarette with a filter, such as saliva attached to the outer layer of paper, or when the teeth and the lips rub against the outer paper, the surface portion of the paper outside the end of the filter is peeled off in a state of being subjected to a so-called paper layer. Stripped. In order to avoid the problem of the above outer paper, a technique for imparting water resistance has been generally practiced. This technique is a method of forming a hydrophobic coating agent (containing a confirmed fiber as a hydrophobic substance) by printing coating on the surface of a paper-containing bottom fabric. Such a technique can exert a certain water resistance effect in accordance with the basis weight of the hydrophobic coating layer. However, only the outer layer paper having a hydrophobic coating layer of about 0.8 gsm based on the basis weight of the nitrocellulose is formed, and the water effect is insufficient. In fact, the paper layer of the outer paper will be peeled off due to insufficient water supply. Therefore, only the simple hydrophobic coating layer of the conventional general art is formed, and the function of water resistance required for the outer layer paper is insufficient, and from the viewpoint of water resistance, a high-quality outer layer paper is sought. Based on the above, it is disclosed in Japanese Laid-Open Patent Publication No. Hei 7-316996. No. 3,321,929, 2011, the entire disclosure of which is incorporated herein by reference. The sizing agent is further coated on the surface of the woven fabric to which the sizing agent is added to further increase the surface sizing degree and impart water resistance. However, the effect of the sizing agent is only to delay the penetration of the water into the bottom fabric, rather than to substantially strengthen the bonding strength between the pulp fibers of the base fabric, but only the function of forming the hydrophobic material layer of the prior art. . Therefore, even if such a roll paper is applied to the outer paper, the water resistance effect is still insufficient. Moreover, the above-mentioned application of the roll paper to the outer paper, the extreme sizing of the outer paper significantly impairs the sizing suitability of the cigarette with the filter attached. A porous plug wrapper is disclosed in Japanese Laid-Open Patent Publication No. 2000-64192, which is a porous filter wrapper in which a filter is directly coated, wherein a wet strength substantially containing an alkyl ketene dimer is added. A strengthening agent, and coating with a polyvinyl alcohol slurry composition to increase the wet tensile strength. However, the porous filter wrapper is different from the tobacco strip and the filter through the integrated outer layer paper. For example, the coating of the above sizing composition is applied to the outer surface of the paper, and it is obvious when the cigarette with the filter is manufactured. Ground damage and sizing suitability. SUMMARY OF THE INVENTION An object of the present invention is to provide an outer layer paper and a high quality filter-attached cigarette having the outer layer paper, which is excellent in water resistance when used in a cigarette with a filter. It is effective in suppressing or even preventing the adhesion of saliva during smoking or the peeling of the paper layer caused by the friction between the teeth and the lips, and the ink is excellent in fixation. The first aspect of the present invention provides an outer layer paper comprising pulp and calcium carbonate as a filler of 4,321,929, 2011,32,301, the amount of the calcium carbonate being at least 5% by weight relative to the total basis weight of the pulp and the calcium carbonate, and Further, a hydrophobic coating layer is formed on the surface of the base fabric containing a strengthening agent for wet paper. According to a second aspect of the present invention, there is provided a cigarette with a filter attached to the outer paper. [Embodiment] [Model for carrying out the invention] Hereinafter, an outer layer paper and a cigarette with a filter according to an embodiment of the present invention will be described in detail. The outer layer paper of the embodiment comprises pulp and calcium carbonate as a filler, the amount of the calcium carbonate being at least 10% by weight relative to the total basis weight of the pulp and the calcium carbonate, and further comprising a bottom fabric containing a moist paper strength enhancer The surface forms a hydrophobic coating layer. The π bottom fabric surface herein refers to all of the faces on the side opposite to the side adjacent to the surface of one of the wrapped tobacco rods and the entire filter when applied to the cigarette with the filter. The above-mentioned outer layer paper was found based on the following knowledge and insights. (1) The water resistance of the outer layer paper was composed of a base fabric containing a pulp having a basis weight of 37 gsm and a moist paper strength enhancer (polyamine-epichlorohydrin: PAE). The amount of PAE added to the pulp (maximum: 1.5% by weight) was changed to obtain an outer layer paper. The tensile strength of each of the obtained outer paper sheets was measured by the following method. The results are shown in Fig. 1. 5 321929 201132301 (tensile strength when wet) Cut the outer paper into a test piece of 15mm width, and immerse it in the water tank in the 12mm center of the length ^#. After the water is fully infiltrated, it will be backwards. The test piece was taken out from the water tank. Then, the excess moisture was rubbed to measure the tensile strength. The tensile strength was measured by using a constant-speed elongation type &1 & and a test machine (Tensilon tensile test machine). Untouched, violated the four ends of the direction After the movable handle (kn〇b) of the measuring device, the length of the spoon moves, and at the fixed speed, the test piece will be broken and the load will be broken and recorded in Newtons (N) (according to jIS 8135). As can be seen from Fig. 1, the tensile strength of the outer layer of the outer paper which is not added with the strength of the wet paper is 〇, and ρΑΕ β) is added to impart water resistance. The crepe paper (2) the water resistance of the outer paper It is confirmed that the outer layer of paper containing the wet paper strength contained in the base fabric and the conventional technique are changed in the bottom fabric table β() to form a layer of the hydrophobic coating layer, and the printing problem is pure. The functional effect of the paper layer peeling off and the practical effects accompanying the action. In the assessment, it was difficult to confirm the amount of outer paper, so the water resistance assessment was carried out with the actual model of the following model. Moulding inspection (10) Run-grid friction test) (wet and anti-friction test) Wear resistance is based on the vibration mode of the semi-cylindrical friction body (size and test machine. Friction benefit system 20 faces, radius of curvature 45mm , the length of the 15^ part of the length of the mx width &, and the 100g round jaw-shaped hammer (diameter - height 24inm) mounted on the upper surface of the friction body of the model 321929 6 201132301 body ° ° in the friction n of the friction body The bottom surface portion is provided with a self-coloring test paper for the size of the bottom surface portion (four). Further, a surface of the test paper is attached with a glass tape, and the test paper itself is not broken by moisture. A printed test piece (printed test piece) is fixed on a rectangular flat surface of a semi-cylindrical non-mineral steel disk having a radius of curvature of 2 GGmm. The frictional phase test is to apply the above-mentioned friction device to the above-mentioned white test paper and the test piece. Placed on the printed test piece of the above stainless steel disk in abutting manner. After the 20/zl water is dropped into the syringe between the friction device and the printed test piece, the test machine is started immediately, and the friction machine is printed. The test piece began to rub back and forth between the test pieces. The evaluation recorded the number of times of single-pass rubbing at the point when the paper layer was peeled off on the test piece by the naked eye. In this evaluation, the higher the number of wet rub resistance is meant to be The higher the resistance (effect) of the paper layer peeling during the containment, the result is shown in Fig. 2. In addition, the broken line of the second drawing is formed on the surface of the bottom fabric to which the wet paper strength enhancer (pae) is not added to form nitrification. The fiber (NC) basis weight is 0.4 g Srn of nitrocellulose (NC)-containing hydrophobic coating layer outer layer paper. As can be seen from Fig. 2, as the amount of wet paper strength enhancer (PAE) increases, The wet rubbing resistance of the peeling of the paper-like paper layer is increased. However, the water resistance of the paper layer exfoliated to the paper layer is the same as that of the outer layer paper of the prior art which forms only the NC layer. (3) Wet paper strength enhancer The effect of the combination of the addition and the formation of the hydrophobic coating layer is as described in the above (2), and the effect of peeling off the paper of the paper 7 321929 201132301 containing the outer layer of the wet paper strength enhancer is as follows by simply printing and coating. Forming a hydrophobic coating layer is almost equal, not necessarily From the above, the inventors of the present invention have reviewed the improvement of the function by the addition of the combined wet paper strength enhancer (PA E) and the formation of the hydrophobic coating layer. That is, separately prepared: The pulp amount contains 1.0% by weight of wet paper strength enhancer (PAE) size 20mm x 250mm outer layer paper (Comparative Sample 1), and the surface has a basis weight of 0.5gsm (nitrocellulose basis weight: 0.4 gsm) to form nitrocellulose-containing hydrophobicity. The same size (2〇tnmx 250mm) outer layer of the coating layer (Comparative Sample 2), and io% by weight of the wet paper strength enhancer (PAE) relative to the amount of pulp and a surface basis weight of 0.5 gSm (nitrocellulose Basis weight: 0.4 gsm) The same size (20 mm x 250 mm) outer layer paper (test sample 丨) forming a hydrophobic coating layer containing nitrocellulose. The same wet rub resistance test as in the above (2) was carried out with respect to the samples, and water resistance evaluation was performed. The results are shown in Fig. 3. At the same time, the addition effect (predicted) of Fig. 3 is a result obtained by summing the wet friction resistance times of the comparative samples 1 and 2 purely. Prepared separately: a moisture-containing paper strength enhancer (PAE) having a volume of L0% by weight relative to the paper amount of 20 mm x 250 mm outer layer paper (Comparative Sample 3), and a surface basis weight of 1.0 gsm (basis weight of nitrocellulose: 〇 8 gsm) An outer layer paper (Comparative Sample 4) forming a hydrophobic coating layer containing nitrocellulose, and 1.0% by weight of a wet paper strength enhancer (PAE) relative to the amount of pulp and having a basis weight of 1.0 gsm (basis of nitrocellulose) Weight: 8.8 gSm) An outer layer paper (test sample σσ 2) forming a hydrophobic coating layer containing nitrocellulose. With respect to the same σ, the same wet abrasion resistance test as in (2) above was carried out in 321929 8 201132301 and water resistance evaluation was performed. The results are shown in Fig. 4. At the same time, the additive effect (prediction) in Fig. 4 is a result obtained by simply comparing the wet rubbing resistance times of the comparative samples 3 and 4. It can be seen from Fig. 3 that in the evaluation model of adding friction in the wet state, the combination of the addition of the wet paper strength agent (PAE) and the formation of the hydrophobic paint layer 1 is a sample of the sample 1 The total of the wet rub resistance times of Comparative Example 1 in which only the wet paper strength enhancer (PAE) was added and Comparative Example 2 in which only the hydrophobic paint layer was formed (predicted), and the peeling of the paper layer on the outer paper was confirmed. The financial effect is increased by the land. As can be seen from Fig. 4, even if the basis weight of the nitrocellulose of the hydrophobic coating layer is twice that of the test sample 1 of the sample 1, the wet and rub resistance times are far more than the comparative example of the wet paper strength enhancer alone. 3, the sum (predicted) of the number of times of wetting and rubbing of Comparative Example 4 in which only the hydrophobic coating layer was formed (nitrocellulose basis weight: 2 times), and it was confirmed that the water resistance effect on the paper layer peeling of the outer layer paper was similarly Multiply the increase. (4) The theoretical investigation of the multiplication effect obtained by the combination of the addition of the wet paper strength enhancer and the application of the hydrophobic paint layer is prepared separately for theoretical consideration of the multiplication effect: 1.0 weight relative to the pulp amount % wet paper strength enhancer (PAE) size 15mm x 2G〇mm outer layer paper (comparative sample 1), forming the same size (i5mmx200mm) outer layer of hydrophobic paint layer based on nitrocellulose basis weight (comparison Sample 2), and a wetting force enhancer (PAE) containing 1.% by weight relative to the amount of pulp and forming an outer layer of the same size as a hydrophobic coating layer having a nitrocellulose basis weight of 4 gsm ( After test sample 1), a higher precision test of 9 321929 201132301 was carried out. Each of the samples was held in a state of a fixed weight (10 N/15 mm), and water of iGQ#L was spread into a strip shape in the width direction on the surface side, and the change in tension with time was measured. The results are shown in Fig. 5. In addition, in the flute (5) 、 , the area where the tensile strength is lower than 4.0 N/15 mm is used as the area where the paper layer is separated. In Fig. $, a is only the evaluation curve of the addition of μ^^ (10)1, the evaluation curve of the sample 2 of the hydrophobicity 荠^, 曰艿/, and the comparison of the sample C of the c-series. 4 Evaluation curve of test sample for formation of aqueous coating layer. ' From the 5th figure, Ke Ming Lu, only the wet paper strength enhancer (PAE) contains (^, the outer paper is after the spread of water, the tensile strength is suddenly under the sudden '咏1' is still maintained The strength of the tensile strength == reflects the result of the abrasion resistance test when the outer layer paper is only wet/forced, which has a lower effect on the peeling of the paper layer. It occurs below the intensity level near the inflection point of the tensile strength. Only the comparison of the formation of the hydrophobic coating of the 3 nitrocellulose is shown in Fig. 5, which shows the tensile resistance after the dispersion of water. The reduction of the strength of the 2 匕 3 has a comparison of the wet paper force PAE)! The person is more slowly moving in. However, after the paper has peeled off after a certain period of time, it is broken. The decrease in the tensile strength of the secret is caused by the penetration of the hydrophobic coating agent on the surface toward the inside of the outer paper, and the knot between the pulp fibers is slowly dissociated. Since the hydrophobic coating layer on the surface is not a strong bond between the two pulps, it is understood that the peeling through the paper layer will eventually reach the point of breaking. From these facts, it is understood that even if the outer layer paper is formed only by the 321929 10 201132301 water coating agent layer, it is impossible to exert a sufficient effect. The combination of the wet paper strength enhancer and the hydrophobic paint layer forming the outer layer of the sample 1 as shown in Fig. 5, the high tensile strength retention property after water dispersion is a wet rub resistance test The result obtained is full of knives reflecting the 'can be _, tolerate the multiplication effect. At the beginning of the water dispersion, the effect of the hydrophobic coating layer becomes dominant and the tensile strength is reduced. Thereafter, δ has an effect of increasing the strength of the wet paper, maintaining a high tensile strength and gradually decreasing. I. It is understood that the additive effect obtained by the formation of the combined wet paper strength enhancer and the formation of the hydrophobic coating layer is derived from the following operation. If the person is 'as shown in Fig. 5', the estimated time for peeling off the outer layer paper containing only the wet paper strength enhancer is a, and only the hydrophobic coating is formed. In this case, the simple addition effect should be ab. However, in the result of the test, when the combination of the content of the wet paper strength enhancer and the formation of the hydrophobic coating layer is formed, the side to the side where the peeling occurs is 5 or less. The time is far beyond the time of (4). From this fact, it can be understood that the effect of the extension to the time when the peeling occurs is a multiplication effect. Although this is a push, the combination of the content of the moist paper strength enhancer and the formation of the hydrophobic paint layer is theoretically: the wet turbid paper strength enhancer (pY illusion is not sufficiently attached) should be considered water resistant The bonding site of the weak paper fibers is protected by the hydrophobic coating agent to make the hydrophobic coating agent have strong potential water resistance. 曰 In addition, in the above test results, the specific wet friction test knot 321929 appears: (1 201132301 is a more significant additive effect. It can be considered that the friction is strongly rubbed by the application of the wetting and friction test, and it is a test with a very high load compared with the above test for maintaining the tension of the fixed weight. The amount of the moist paper strength enhancer contained in the paper may hinder the fixing of the ink. For example, when the cork printing is performed on the outer paper, the ink pigment is liable to fall off and the ink mottling is easily caused in the printing quality. The inventors of the present invention can improve the fixability of the ink by making the calcium carbonate as a filler at least 10% by weight based on the total basis weight of the pulp and the calcium carbonate. In the state, by combining the above-mentioned wet paper strength enhancer with the formation of a hydrophobic coating layer, and by using a calcium carbonate as a filler, when used in a cigarette with a filter It exhibits excellent water resistance, can effectively inhibit or even prevent the adhesion of saliva during smoking, or the peeling of the paper layer caused by the friction between the teeth and the lips, and can compensate the moistening paper strength enhancer with the above calcium carbonate. In addition, the outer layer paper of the embodiment is used in the case of the above-mentioned excellent water resistance, and it can be confirmed when the cigarette with the filter is used. Damage at the front end of the filter; breakage and breakage at the opening; breakage and breakage of the black line at the junction of the rod and the filter; prevent the outer paper from adhering to the lip (improving the lip function). The pulp to be contained may be any one as long as it is a user of a general outer layer paper, and examples thereof include wood pulp classified into L material (broad-leaved tree) and N material (coniferous tree); bagasse, flax, Non-wood pulp such as hemp; mechanical pulp obtained by simply grinding the wood; chemically treated to obtain chemical pulp of 12 321929 201132301. Calcium carbonate as a filler contained in the base fabric, relative to pulp and carbonic acid: i The total basis weight of the bow is at least 10% by weight. When the content of the carbonic acid 4 is less than 10% by weight, it is difficult to improve the ink fixing property of the outer paper. Preferably, it is based on the total basis weight of the pulp and calcium carbonate. The content of calcium carbonate is 10% by weight or more and 30% by weight or less, preferably 20% by weight or more and 30% by weight or less. Further, the total amount of titanium oxide as a filler in the base fabric relative to pulp, calcium carbonate and titanium oxide. The basis weight is not more than 20% by weight. 1 The wet paper strength enhancer contained in the base fabric may be any one as long as it has a wet paper strength function. Examples thereof include: Indoleamine-epichlorohydrin (PAE), polyethyleneimine, epoxidized polyamine, polypropylene decylamine. In particular, polyamine-epichlorohydrin is preferred. The content of the wet paper strength enhancer is preferably 2.0% by weight or less, more preferably 0.5% by weight or more and 2.0% by weight or less, and more preferably 0.8% by weight or more and 1.2% by weight or less based on the pulp contained in the base fabric. The hydrophobic coating agent is preferably one containing nitrocellulose (NC) as a hydrophobic substance. In particular, the hydrophobic coating agent preferably contains a plasticizer and a resin component in addition to NC. For example, the hydrophobic coating agent is preferably a colored hydrophobic ink containing NC and a pigment suitable for gravure printing. The hydrophobic coating layer containing nitrocellulose is formed on the surface of the bottom fabric by the weight of the nitrifying fiber, which is O.lgsm or more and less than 1.0 gsm, and is preferably formed to be 0.2 gs or more and 0.8 gsm or less based on the basis weight of the nitrocellulose. By. Next, a cigarette with a filter attached to the embodiment will be described. 13 321929 201132301 The filter-attached cigarette of the embodiment has the above-mentioned paper having excellent water resistance. Refer to Figure 6 for a detailed description of the specific cigarette with a filter. The cigarette with the filter is used to closely align the tobacco rod 1 with the filter 2, and the outer peripheral surface of the outer layer paper 3 wrapping the filter 2 and the outer peripheral surface portion of the tobacco rod around the closely aligned portion, so as to have a tobacco rod The structure in which the crucible and the filter 2 are integrated. The tobacco rod 1 is formed by winding a roll paper 5 into a cylindrical shape on the wire 4. The mouth 2 is bundled or folded by, for example, an acetate fiber or a (4) nonwoven fabric. The molded guillotine (not shown) is formed of a pulp paper 6 in which the nozzle material is wound into a cylindrical shape. The outer paper 3 contains paper aggregates and carbon as a filler with respect to the total weight of the pulp and the above-mentioned carbonated dance, the amount of the above calcium carbonate being at least 10% by weight, and further on the surface of the bottom fabric containing the paper-reinforcing strength enhancer The entire surface of the surface on the side where the surface is exposed is formed by, for example, forming a hydrophobic coating layer containing the confirmed fiber on the basis of the stone-based fiber base 4.

Moreover, for the fixing of the ink (printing black dislocation, paper, the printing method was determined by the following method. The results are shown in Table 1 below (fixation of ink). The fixability of the ink must be evaluated for both the stability of the ink, and the abrasion resistance and the peeling are half. When the material vibrating material is rubbed, the friction machine is 2? cylinder:; the friction body (dimension: the length of the bottom part is 1 axis, 1%), the material is installed in the friction machine, the surface is 200, and the weight is 45_height Μ—Guang and Qiu; I: Install the white test paper with the size of the outer surface of the friction body of the above friction 2.

The white test paper is placed adjacent to the test piece and placed on the printed test piece of the non-mineral steel plate, and the test piece of the transfer brush is rubbed back and forth by 5. After that, the test paper is observed. : De-stabilization is to observe the degree of discoloration when the adhesive tape of the city f is peeled off immediately after the (10) R load on the test piece. The ink-fixing system obtained by such a test has a significant ink transfer when the adhesive tape is observed or adhesive.

In the comparison of the formation 2 and 3, the number of times of wet friction resistance was significantly increased and the water resistance was excellent. Further, a comparative paper 4 outer layer paper containing a wet paper strength enhancer (PAE) related to the hindrance of ink fixing property and containing not less than 10% by weight (7% by weight) of calcium carbonate (CaC03) as a filler Ink retention is inferior. On the other hand, although the wet paper strength enhancer (PAE) related to the hindrance of the ink fixing property is contained, the amount of calcium carbonate (CaC03) as a filler is 10 weight 〇/〇 (10% by weight, 30% by weight). In the above test 1, 2 outer layer paper, these ink fixing properties are "good" and "excellent". It can be seen that the inks of the outer layers of the tests 1 and 2 are not inferior to the above-mentioned PAE which does not contain the hindrance to the fixation of the ink, and contain 10% by weight, 30% by weight of calcium carbonate (CaCO3) as a filler. Compare the 3, 2 outer layer paper.
