Description of the Invention: [Technical Field of the Invention] The present invention relates to a low-sintering cigarette paper for cigarettes, particularly for cigarettes having a low burn-in property and a low C/T ratio (carbon monoxide/tar ratio) Roll paper. ^ [Prior Art] In order to make the cigarettes fall on the bed or the like due to the negligence of the smoker, etc., it is difficult for the fire to prolong the burning of the bed and the like. It is recommended to set the strip of the flame retardant material on the original roll paper. A cigarette paper for cigarettes (refer to Japanese Laid-Open Patent Publication No. Hei 7-300795). This technique is based on the observation that when a high-flammability zone and a low-flammability zone are provided on a tobacco roll paper, even if smoking is generally performed in a high-flammability zone, when a substance is in contact with a cigarette in a low-flammability zone, the cigarette itself is made. Extinguish the knowledge gained. However, when a cigarette is manufactured using the above-described conventional low-calorie roll paper, the carbon monoxide/tar ratio (C/T ratio) per cigarette is not sufficiently low. SUMMARY OF THE INVENTION Accordingly, the present invention has been made in an effort to provide a roll paper for cigarettes which exhibits low burntability while having a low C/T ratio. One aspect of the invention provides a low-sintering cigarette paper roll having a filler basis weight (grammage, also referred to as a basis weight) of from 16 to 22 W in a ratio of from 2 to 6 W, and a dispersion on the surface of the side of the pair. A flame-retardant zone coated with a flame retardant, the total coating amount of the flame retardant being 〇·2 to 18 丨 per 丨m 2 . [Embodiment] Hereinafter, the present invention will be described in more detail. 317990 5 1302090 ' The cigarette paper of the present invention is a flame-retardant region in which a resist-and-burning agent is applied to a roll paper. Although the original roll paper is a base material made of pulp such as ordinary linen paper used for cigarette paper for cigarettes, it contains a filler in a ratio of 2 to 6 g/m 2 and has a basis weight of 16 to 22 g/m2. As the filler, a carbonate such as calcium carbonate or potassium carbonate, or a hydroxide such as potassium hydroxide or magnesium hydroxide can be used. In the cigarette paper, a combustion regulator such as citric acid or a salt thereof (sodium salt, potassium salt) may be added. In general, in the case of blending the combustion modifier, a ratio of up to 2% by weight is used in the original roll paper. A flame-retardant region is formed by coating a flame retardant on the surface of one side of the original roll paper. When the tobacco strip is used to roll the tobacco rod, the flame-retardant region may extend in the longitudinal direction of the tobacco rod, and may be disposed in a plurality of stripe shapes separated from each other in the circumferential direction of the tobacco rod, or may extend in the circumferential direction of the tobacco rod. In the longitudinal direction of the tobacco rod, a plurality of annular shapes are separated from each other. 2至1. 8 g。 The total amount of the coating agent (dry weight calculation) is 2 to 1.8 g per 1 m2. As the flame retardant, proteins such as gelatin, casein, albumin, gluten, etc.; starch, xanthan gum (ec gum), locust bean gum, guar pack (guar pack) can be preferably used. , Xihuang gum, thorn cloud glue, tamarind seed polysaccharide (glyloid) karaya gum, gum arabic, poly = glucose ^ dextrin ~ cyclodextrin ^ ^ "(10) ... (3) ^ Gedi gum, etc. / :: Acting polysaccharides; carrageenan, carterin, agar, gelatin, spirulina, pectin, gellan gum, kelcogel, etc. have gelation dual use: 317990 6 1302090 degrees. 11 usually has a circumference of 17 mm to 26 mm and a length of 49 to 90 mm. At the base end of the tobacco rod u (ie, the downstream end of the suction direction) lib, it can be installed by using a cigarette paper 17 by a usual method. A general filter 18. A ring-shaped region 14 coated with a flame retardant is formed on the original roll paper 12 to set a flame-retardant region. These annular flame-retardant regions 14 are provided in plural as shown in the figure. Next, they are formed at intervals in the longitudinal direction of the tobacco rod. ^ ❿ In the adjacent annular shape Between the combustion zones 14, a general combustion zone 15 to which a combustion modifier is not applied is defined. Since this zone 15 is composed of a part of the original roll paper 12, it can be burned under the general smoking state as the original roll paper 12 itself. Therefore, the function of the region 15 serves as a general combustion region. For example, one to three annular flame-retardant regions 14 may be provided. Further, the annular flame-retardant region 14 may have a longitudinal width of 4 mm to 7 mm. The thickness system can be from 0. 1 to 5 // m. Further, in the case where a plurality of flame-retardant regions are provided, the interval between adjacent flame-retardant regions 14 is preferably 18 mm to 25 mm. In the cigarette shown in Fig. 1, no flame retardant is applied to the region 16 spaced apart from the front end by a distance of 4. The portion where the flame retardant is not applied to the tip end portion can also constitute a general combustion region 16, which can be equivalent to a general cigarette pumping. In the case where a plurality of flame-retardant regions 14 are provided, the general combustion region 16 may not be provided (d = 0). However, in the case where i flame-retardant regions 14 are provided, , so that the distance d is 10 mm to 25 mm from the front end of the tobacco rod 11a In the inner surface of the roll corresponding to the portion of the roll paper 12 covered by the mouthpiece paper π, the formation of the flame-retardant region 14 is not particularly necessary for 317990 8 1302090. Next, the front end 11 of the tobacco rod 11 for igniting the cigarette 10 is ignited. a. The cigarettes that are being sucked are burned, and in the general combustion area 15, they can be burned in the same manner as a general cigarette, and the taste of the cigarette can be tasted. However, the cigarettes in the ignited state are placed on the carpet, tatami, In the case of flammable materials such as wooden products, cloth, clothes, etc., since the flame-retardant region 14 present in the burning direction and the heat absorbing of the combustibles complement the expanded tobacco contained in the tobacco filler, the cigarette 10 is extinguished to suppress Extended burning of combustibles. Furthermore, the C/T ratio in the mainstream smoke of cigarettes wrapped in the cigarette paper of the present invention is low. Hereinafter, the embodiments of the present invention will be described, but the present invention is not limited to the embodiments. Examples 1 to 13, and Comparative Examples 1 to 12 In the raw rolls of the specifications shown in Table 1 (width 27 mm, length 1500 m), various concentrations (0.5 to 20% by weight) of aqueous sodium alginate solution were used. The φ direction was applied (printed) in a stripe shape by a direct gravure at a constant interval of 7 mm at a constant width of 7 mm, and a total of 56 flame retardant application regions were provided. The total amount of sodium alginate applied was measured for the obtained roll paper by the following method. The results are recorded together in the form. As shown in Table ,, the examples i to 13 were coated with a flame retardant (a sodium alginate) per 1 m 2 in an area of 〇 2 to 1.8 g of a flame retardant. When the coating amount of the flame retardant is converted to the area per roll, it is 〇. 〇5 to 〇· 47 W because it is multiplied by 7/27. Further, sodium alginate used, in Examples 5, 8 and u, was I-S manufactured by kimika (registered trademark) (degree of polymerization: 650 to 670; 3 wt% of water-soluble 317990 9 1302090 liquid at 25 ° C) The viscosity is 29976·9 cP), and in other examples, it is il-2 manufactured by KIMIKA (registered trademark) (degree of polymerization: 30 to 180; 3 wt% aqueous solution, viscosity at 25 ° C is 907. 2 cP). Using the obtained roll paper package, the tobacco rod consisting of American mixed cut tobacco (the amount of tar in the case of no additional nozzle: 19 to 20 mg) is arranged with a width of 5 mm from the burning front end of the cigarette. The area is cut off in such a way. Each cigarette has a length of 59 mm and a flame retardant coating area of two. • The obtained cigarette was subjected to a burn-in test according to ASTM E-2187-04, and the value of PFLB (percent ful length burn) was measured. Further, the amount of CO, the number of extractions, and the amount of tar in the mainstream smoke of each cigarette sample were measured for these cigarette samples by the following method. The results are shown in Table 2. <Measurement of total coating amount of sodium alginate> According to "Food Hygiene", Vol. 5, pp. 297 to 3, page 2 (1988), "Quantitative Analysis Method of Sodium Alginate in Food", The degreasing, dilute sulfuric acid treatment and deproteinization treatment were not carried out, and the measurement was carried out by the following procedure. A roll paper of 5 〇〇 m, width 27 咖 (about 1.0 g) coated with the above flame retardant was cut into a square of 5 mm, and a 4 wt% aqueous solution of sodium hydrogencarbonate was added. After heating in a hot water bath of 6 (TC) for 5 minutes, the mixture was thoroughly mixed and stirred, and the supernatant liquid (extract solution) was obtained by centrifugation (3500 rpm, 1 minute; the same applies hereinafter.) The extraction residue was again subjected to the same The extraction is carried out to obtain the supernatant (extract). At the same time, 2% by weight of the aqueous solution of sodium carbonate is added to the extraction residue (4), and the mixture is thoroughly mixed and scrambled to obtain the supernatant (extract). Add the extract together, add 1% by weight of sodium hydrogencarbonate 317990 10 1302090 solution to 100 mL as the test solution. In the sodium alginate standard solution (1 weight of sodium alginate containing 〇 to 2 mg / mL concentration) % aqueous solution of sodium bicarbonate) and 2 mL of the above test solution were added with 2 mL of copper-hydrochloric acid solution (8·5 Μ hydrochloric acid containing 5 wt% of copper sulphate) and 1 mL of naphthalene The dip solution (〇·4 wt% aqueous solution of 1,3-dihydroxynaphthalene) was heated in a boiling water bath for 65 minutes and then cooled in ice water. 'Add 4 mL of butyl acetate to be shaken off and centrifuged. After centrifugation, take 1 mL of the supernatant and add 3 mL of butyl acetate was diluted and quantified at 566 nm to calculate the total coating amount. <Measurement of C0 amount and number of extractions> In the measurement of C0 amount, 8 samples of FILTR0NA were used for extraction. The linear smoker (SM342) collects tobacco smoke. The burning of cigarettes is based on ISO standard '35 mL/2 seconds at 60 second intervals, and the smoke is collected in a gas bag through a fiberglass filter. The cigarette samples reach the standard. Burning length (at a point of time 51 mm from the ignition end of the cigarette (8 mm from the uranium end of the roll paper and the mouthpiece paper boundary)). Record the number of extractions up to this point. In order to collect the residual gas in the burned cigarette, After the fire is removed, three evacuations are performed. If so, the gas of the cigarette sample is collected in an air bag to collect the total flow material (TPM) in the glass fiber filter. The collected air bag is used by FILTR0NA. The C0 measuring device manufactured by the company measures the amount of C0 per cigarette sample. <Measurement of tar amount> When the amount of C0 is measured, the particles collected from the glass fiber filter are placed into a coarse tar after the knife is placed.
