Description

Roll paper for non-combustion heating type smoking article, non-combustion heating type smoking article and electric heating type smoking system

The invention relates to a roll paper for non-combustion heating type smoking articles, non-combustion heating type smoking articles and electric heating type smoking system.

A non-combustion heating type smoking article that is heated from around a tobacco rod containing shredded tobacco to deliver volatile components to the user is known. The non-combustion heating type smoking article heats the tobacco wrapped in paper, but unlike the conventional cigarettes, the tobacco rod does not burn after use (after heating).

In the past, paper cigarettes used to wrap shredded tobacco. Although trademarks are attached, white (colorless) paper is usually used.

For non-combustion heating type smoking articles, it is known that if the paper used for conventional cigarettes is used as the paper for rolling shredded tobacco, it will cause discoloration which is uncomfortable for the user due to heating during use.

Therefore, the subject of the present invention is to provide a non-combustion heating type smoking article roll paper, which does not cause discomfort in appearance due to heating.

In order to solve the above-mentioned problems, the inventors of the present invention focused on making the unpleasant discoloration inconspicuous by using the roll paper of the colored part having a specific range of discoloration area after heating.

Paper made of pulp as the main material, if heated at a temperature higher than a certain temperature, it will be scorched and become brown. The reason is that the physical changes caused by the thermal decomposition of the pulp or paper components, so such discoloration cannot be easily prevention. However, even if discoloration occurs due to scorching, as long as the color of the original paper and the degree of discoloration are reduced to a certain range, it is difficult to visually recognize the uncomfortable brown.

That is, if paper with a small color difference range before and after heating is used, the above-mentioned uncomfortable discoloration problem can be solved. The inventors found that the visually allowable color change range of the degree of discoloration can be expressed by a mathematical formula, by using the mathematical formula to be substituted for each value of L ^* , a ^* , and b ^* to display specific values The colored part of the paper is used as a roll paper to solve the problem of discomfort and discoloration unique to non-combustion heating smoking articles.

The subject of the present invention is unique to non-combustion heating smoking articles heated by electric heating elements, and is a problem that has not occurred in conventional smoking articles (paper cigarettes, etc.).

In this specification, the "roll paper for non-combustion heating type smoking articles" refers to the roll paper used for non-combustion heating type smoking articles described later. Hereinafter, it is also only referred to as roll paper related to the embodiment of the present invention. Regarding the use of the roll paper related to the embodiment of the present invention, the so-called "non-combustion heating type smoking article" refers to the use of tobacco rods that are used to make fillers containing shredded tobacco, or used in packaging such The outer circumference is used to connect members adjacent to the tobacco rod.

The roll paper related to the embodiment of the present invention has a colored portion, and the colored portion is: L ^* , a ^* , b ^* measured before and after heating at 230°C for 3 minutes (also called just before and after heating), respectively △L ^* , △a ^* , △b ^{* are} used to express the difference between the values before and after heating (the value obtained by subtracting the value before heating from the value after heating), and the equivalent value is substituted into the following formula (1). The y (discrimination score) has a value smaller than 0.62.

Discriminant score (y) y=-0.18×△L ^* +0.08×△a ^* +0.13×△b ^* -2.36 (1)

The roll paper related to the embodiment of the present invention only needs to have a colored part where the values of △L ^* , △a ^* , and △b ^* are substituted into the above formula (1) and the discriminant score obtained shows a value smaller than 0.62. The previous values of L ^* , a ^* , and b ^* are not particularly limited.

In addition, the above-mentioned colored part may exist on the entire surface of the roll paper according to the embodiment of the present invention, or may exist at least on the heated portion (heated by the electric heating element described later).

The L ^* value of the colored part before heating is low (the one with heavy dark color feeling), but the appearance after heating tends to be good. The value of L ^* before heating in one form of roll paper as the colored part can be, for example, 90 or less.

The following examples show that if the y (discrimination score) obtained by the above formula (1) is less than 0.62, there will be no discomfort in appearance due to heating. Moreover, if the y (discrimination score) obtained by the above formula (1) is less than 0, it can more reliably include those that do not impair the appearance before and after heating.

In addition, in the roll paper related to the embodiment of the present invention, the values of L ^* , a ^* , and b ^* before and after heating are measured at 5 points of the colored part of the sample paper, and the simple average value is adopted. Although the measurement target is an arbitrary point on the colored part of the paper, when the paper has characters or drawings such as a trademark, the colored part where there is no such text or trademark is the target. The values of L ^* , a ^* , and b ^* can be measured with a spectrophotometer.

Specifically, a spectrophotometer (manufactured by X-Rite Corporation, product name SpectroEye) was used. The measurement is performed with a light source D65, no light source filter, and a viewing angle of 2°. A piece of sample is placed on an ISO whiteness 92% paper, and the measurement part of the spectrophotometer is pressed on it.

There are no particular limitations on the means for preparing paper (also referred to as paper with the above-mentioned characteristics) having a colored portion whose discriminant score obtained by the above formula (1) shows a value less than 0.62, and well-known methods can be used.

For example, printing can be performed on the roll paper that has been used in the past or an appropriate paper to obtain a roll paper having a colored portion showing a desired hue. That is, the colored portion existing in the roll paper related to the embodiment of the present invention may also be provided by printing. When the roll paper has a colored portion by printing, the roll paper having the above characteristics can be easily provided.

The printing method is not particularly limited, and examples include gravure printing and offset printing. The L ^* value of the colored part can be changed to be 90 or less by printing, for example.

For example, the printing may be performed on the entire surface of the base paper, or at least the heated part of the electric heating element described later is used as a colored part. In addition, the printed surface of the colored portion can be used as the target of the discriminant analysis by the above-mentioned formula (1). On the other hand, when a trademark or partial pattern is provided as a colored portion on the base paper by printing, the printed surface (printed portion) is not the color measurement object of the spectrophotometer.

On the surface of the roll paper, it is preferable that at least the heated part (the part heated by the electric heating element) is a colored part whose discriminant score obtained by the above formula (1) is less than 0.62. In the surface of the roll paper, by making the portion heated by the electric heating element have the above characteristics, it is possible to prevent deterioration of the impression of the appearance after heating.

In addition, the composition of the roll paper material described later can be changed to have a colored portion with a discriminant score obtained by the above formula (1) that is smaller than 0.62. Specifically, for example, adjusting the content of the filler described later, adding shredded tobacco to the pulp, and increasing the content of unbleached pulp by adding it.

The basis weight of the roll paper according to the embodiment of the present invention is, for example, usually 20 g/m ² or more, preferably 35 g/m ² or more, and more preferably 40 g/m ² or more. On the other hand, the basis weight is usually 65 g/m ² or less, preferably 50 g/m ² or less.

When used as a roll paper for rolling shredded tobacco (for making tobacco rods), the length of one side can be about 15 to 70 mm, the length of the other side can be, for example, 15 to 26.5 mm, and the preferred length of the other side can be Take, for example, 24mm.

In the case of a cigarette holder paper that connects the cigarette rod with other members adjacent to the cigarette rod, for example, the length of one side is 20 to 60 mm, and the length of the other side is 15 to 26.5 mm.

Examples of the roll paper having the above-mentioned characteristics include pulp as the main component. In addition to using wood pulp such as conifer pulp or hardwood pulp as paper pulp, it can also be mixed with non-wood pulp used in the roll paper used for general smoking articles such as flax pulp, hemp pulp, hemp pulp, and reed pulp. Gainer.

The types of pulp can be chemical pulp, groundwood pulp, chemical groundwood pulp, thermal grinding machinery obtained by kraft pulp (kraft) steaming method, acidic, neutral, alkaline sulfite steaming method, sodium salt steaming method, etc. Pulp etc.

In addition, the pulp may be composed of, for example, a mixed pulp of bleached pulp and unbleached pulp.

Even when it is composed only of bleached pulp, paper that is colored by printing can also be used.

Prepare spruce and broadleaf poplar as bleached pulp, and prepare pine as unbleached pulp. Put the desired ratio of bleached pulp and unbleached pulp into a pulping machine to dissociate the pulp, and move the dissociated pulp to a refiner for beating. In addition, calcium carbonate as a filler and a flocculant as a manufacturing aid are prepared, and these are mixed with the beaten pulp. In addition, a plurality of pulping machines can be used to separate the bleached pulp and unbleached pulp separately, and the refiner is used for beating, and the bleached pulp and unbleached pulp, fillers, and manufacturing aids after beating separately are mixed in the mixing chamber.

Then, during the papermaking step using the mixed pulp by a Fourdrinier paper machine, a cylinder paper machine, a cylinder short-wire composite paper machine, etc., the paper quality is adjusted to make it uniform to produce roll paper. Furthermore, if necessary, the above-mentioned wet paper strength enhancer may be added to impart water resistance to the roll paper, and a sizing agent may be added to adjust the printing conditions of the roll paper. In addition, aluminum sulfate, various anionic, cationic, nonionic or amphoteric product yield enhancers, drainage enhancers, paper strength enhancers and other internal additives for papermaking, dyes, and pH adjustments can also be added. Additives for paper making, such as additives, defoamers, resin control agents and slimeicides.

When bleached pulp and unbleached pulp are used in combination, the proportion of unbleached pulp in the roll paper is, for example, preferably 1% by weight to 9% by weight, more preferably 5% by weight to less than 86% by weight, and more It is preferably not less than 5 wt% and not more than 60 wt%.

In addition to the above-mentioned pulp, the roll paper related to the embodiment of the present invention may not contain fillers. The content of the filler relative to the total weight of the roll paper related to the embodiment of the present invention can be, for example, 30% by weight or more but less than 60% by weight.

As the filler, calcium carbonate, titanium dioxide, kaolin, etc. can be used, and it is better to use calcium carbonate in consideration of smoke smell.

The roll paper containing such a filler is usually a bright white color, but in order to make the discrimination score obtained by the above formula (1) less than 0.62, it may also contain dyes that reduce the brightness, such as black and brown. Dyes and/or dyes such as cyan, dark red, dark green, dark blue, etc. It is better to use pigments with less discoloration due to heating.

In addition, roll paper composed of mixed pulp usually has a color derived from unbleached pulp. It is also possible to perform printing as exemplified above on a roll paper composed of mixed pulp to further impart color.

The tobacco sheet made of reconstituted tobacco can also be used as the roll paper related to the embodiment of the present invention.

The tobacco sheet includes, for example, a paper-making tobacco sheet obtained by a papermaking method, and a slurry tobacco sheet obtained by drying the slurry.

The general manufacturing method of paper-making tobacco flakes includes the following steps: extracting natural tobacco materials (leaf, shredded tobacco, middle ribs, stems, roots, etc.) with an extraction solvent such as water, and combining the extract The step of separating the residue, the step of papermaking the residue to make a regenerated tobacco board, and the step of pouring the extraction liquid, which is subjected to the separation treatment as needed, back to the regenerated board. Such a manufacturing method is described as a wet papermaking method in, for example, International Publication No. 2004/098323.

The slurry tobacco sheet can be produced, for example, by the method described in JP 11-266851 A. The raw material slurry contains wood pulp, tobacco powder, and a binder that are mixed and defibrated in water. The raw material slurry is extruded by the slurry supply machine between the conveyor belt and the roller, and stretched into a sheet on the conveyor belt. After that, the sheet-like raw material slurry on the conveyor belt is conveyed to the drying furnace, and dried while passing through the drying furnace to form tobacco flakes.

When the tobacco sheet is used as the roll paper related to the embodiment of the present invention, its basis weight can be, for example, in the range of 30 to 80 g/m ² , and the air permeability can be, for example, 0 to 60.0 CU (Coresta Unit). ).

Other methods of manufacturing tobacco sheets include, for example, the dry papermaking method described in JP 61-52269 A. The tobacco sheets obtained by this method are composed of wood pulp fibers, adhesives, and tobacco stems.

Tobacco flakes usually have a color derived from tobacco materials, and dyes, pigments, or further printing to impart color can also be used.

The roll paper related to the embodiment of the present invention may also contain the combustion aid contained in the conventional cigarette stick roll paper, or may not contain it. The roll paper according to the embodiment of the present invention can be used as the first roll paper used in the non-combustion heating type smoking article described later, or as the second roll paper.

<Non-combustion heating type smoking article>

Examples of the non-combustion heating type smoking article of the embodiment of the present invention include those having the configuration shown in Fig. 1.

The non-combustion heating type smoking article 10 of Fig. 1 has: a cigarette rod portion composed of a filler 11 and a first roll of paper 12 of the roll filler, and a mouthpiece portion constituting the opposite end of the tobacco rod portion 16. The aforementioned stem portion and the mouthpiece portion are connected by using a second roll paper 13 (the mouthpiece paper in the first figure) that is the same as or different from the roll paper used to wrap the filler.

At least one of the first roll paper and the second roll paper is the roll paper related to the embodiment of the present invention described above. Preferably, at least the first roll of paper is the roll of paper related to the embodiment of the present invention. Moreover, it is also preferable that both the first roll paper 12 and the second roll paper are the roll papers related to the embodiment of the present invention described above.

In the aspect shown in FIG. 1, the mouthpiece portion includes a paper tube portion 14 and a filter portion 15. In addition, there is also a cigarette tip paper 13 for connecting these second rolls of paper. In addition, in Figure 1, the mouthpiece portion 16 is composed of two segments, but the mouthpiece portion 16 may be composed of a single segment, or may be composed of three or more segments. In addition, the segment constituting the mouthpiece portion may be constituted to include both the paper tube portion and the filter portion, or may be constituted by only any of them.

The vapor containing the aerosol-generating substrate and tobacco flavor components generated by the heating of the aforementioned tobacco rod is cooled by contact with the air in the paper house through the paper tube portion 14 so that it is liquefied to produce aerosol.

In addition, the non-combustion heating type smoking article 10 may have a part of the second roll paper 13 (cigarette tip paper) around the paper tube portion 14 and the coated paper tube portion 14, and may have tiny holes for obtaining air from the outside ( Not shown). Due to the presence of such tiny holes, air flows into the inside of the paper tube portion 14 from the outside during use, and the aerosol-generating base material and the vapor containing the tobacco flavor components generated by the heating of the tobacco rod comes into contact with the outside air to make the temperature Lowering and liquefaction can produce aerosol more reliably.

The paper tube portion 14 may be, for example, a thick paper processed into a cylindrical shape.

For the filter unit 15, for example, a user who uses Acetate Tow as a material. The monofilament fineness and total fineness of the acetate tow are not particularly limited.

In Figure 1, the filter unit 15 is composed of only a single segment, but it may also be composed of a plurality of segments. When it is composed of a plurality of segments, for example, a hollow segment is arranged on the upstream side, and the segment on the downstream side (the end of the user's mouth) is filled with acetate tow in the mouth section. In this way, unnecessary loss of the generated aerosol can be prevented, and the appearance of the non-combustion heating smoking article can be improved.

In addition, in the manufacture of the filter, it can be appropriately designed to adjust the air permeability resistance or add additives (known adsorbents or fragrances, fragrance holding materials, etc.).

The material of the second roll paper 13 (cigarette tip paper) is not particularly limited, and the roll paper according to the embodiment of the present invention may be used in part or all. The second roll paper 13 may be, for example, the following form: an acetyl acetate-based paste is used to wrap the above-mentioned tobacco rod, paper tube portion 14, and filter portion 15 and then fix it.

The tobacco rod contains shredded tobacco as the filler 11, and the material of the shredded tobacco is not particularly limited, and known ones such as blades or middle ribs can be used. The content range of the filler in the tobacco rod, when it is a tobacco rod with a circumference of 22 mm and a length of 20 mm, can be, for example, 200 to 400 mg/bar, preferably 250 to 320 mg/bar. The moisture content of the filler can be, for example, 10 to 15% by weight, preferably 11 to 13% by weight. With such a moisture content, the occurrence of curling can be suppressed, and the winding suitability during the manufacture of the tobacco rod is good.

There are no particular restrictions on the size of the shredded tobacco used as the filler or its adjustment method. For example, the tobacco leaf after drying can be shredded to a width of 0.8 to 1.2 mm.

In addition, it is also possible to use dried tobacco leaves to pulverize and homogenize them so that their average particle size is about 20 to 200 μm, process them into flakes, and then shred them to a width of 0.8 to 1.2 mm.

Furthermore, it is also possible to use the one that has not been shredded but has been selected and processed as a filler among the above-mentioned sheet processors.

The filler contains an aerosol generating substrate that generates aerosol smoke. The type of the aerosol-generating substrate is not particularly limited, and extracts from various natural substances and/or these constituent components can be selected depending on the application. The aerosol-forming substrate can include, for example, glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures of these.

In the manufacture of non-combustion heating smoking articles, by using the roll paper related to the embodiment of the present invention as the roll paper of the cigarette rod and/or the cigarette tip paper, it can be provided after use (after heating) without damaging the appearance Impression of non-combustion heating type smoking article.

The non-combustion heating type smoking article 10 according to one embodiment of the present invention is provided with a tobacco rod composed of filler 11 and roll paper 12 (roll paper related to the embodiment of the present invention), a paper tube portion 14 and a filter portion 15, and Used to connect the second roll paper 13. In addition, in the non-combustion heating smoking article 10, a part of the second roll paper 13 around the paper tube portion 14 and the coated paper tube portion 14 may have tiny holes (not shown) for obtaining air from the outside. Due to the presence of such tiny holes, air flows into the inside of the paper tube portion 14 from the outside during use, and the aerosol-generating base material and the vapor containing the tobacco flavor components generated by the heating of the tobacco rod comes into contact with the outside air to make the temperature Reduced and liquefied can more reliably produce angry glue.

<Electric heating type smoking system>

The same state diagram of the electrically heated smoking system is shown in Figure 2. The electric heating type smoking system 30 is arranged inside the electric heating type element 20 and is used by being embedded in such a manner that the non-combustion heating type smoking article 10 described above is in contact with the heat conducting member 25 connected to the heater 24.

The electric heating element 20 has a battery unit 21 and a control unit 22 inside, for example, a resin body 23.

The non-combustion heating type smoking article described above has: a cigarette rod portion composed of a filler 11 and a first roll of paper 12 of the roll filler, and a mouthpiece portion 16 that constitutes the opposite end of the tobacco rod portion , The cigarette stem part and the mouthpiece part are connected by using a second roll paper that is the same as or different from the roll paper used to wrap the filler. If the non-combustion heating type smoking article is embedded in the electric heating element, the outer circumferential surface of the cigarette rod and the outer circumferential surface formed by the second roll of paper (the mouthpiece paper 13) connecting the cigarette rod and the paper tube portion 14 A part of it will be in contact with the heat conducting member 25 inside the electric heating element 20.

The heater 24 inside the electric heating element 20 is controlled by the control unit 22 to generate heat. The heat is conducted to the rod of the non-combustion heating smoking article through the heat conducting member 25, whereby the aerosol generating substrate contained in the filler 11 of the tobacco rod and the flavor component volatilize together.

By the heating of the heater 24, the aforementioned tobacco rod is heated to approximately 150 to 250°C.

[Example]

The following examples illustrate the present invention more specifically, but as long as it does not exceed the gist of the present invention, the present invention is not limited to the description of the following examples.

<Preparation of paper samples before and after heating>

Prepare papers with the values of lightness L ^* , chromaticity a ^* , and chromaticity b ^* in various CIELab color system. Colored paper, for example, can be prepared for intaglio printing, white general pulp mixed with unbleached pulp, and tobacco flakes mixed with fine tobacco leaves. As a completely uncolored paper sample, prepare to use 100% virgin pulp (virgin pulp) general cigarette tip paper base paper and roll paper as a control. Prepare all 26 types of paper.

Its content is shown in Table 1 below.

<Heating conditions>

Adjust the high temperature furnace (product name: Muffle Furnace F0410, manufactured by Yamato Scientific) to 230°C in advance. Open the door and load the paper sample on household aluminum foil (material: aluminum foil thickness: 11 μm), put it in the high-temperature furnace, and close the door. The aforementioned actions must be carried out as quickly as possible (within 3 seconds) to minimize the temperature drop in the high-temperature furnace. In the heating conditions of this embodiment (the temperature of the high-temperature furnace is set to 230°C, and the heating time of the paper sample is 3 minutes), the actual paper temperature is about 230°C which is the same as the set temperature of the high-temperature furnace at the latest 1 minute after closing the door. It was confirmed using a color change temperature test paper (Temperature labe 5E-170/Temperature labe 5E-210 (manufactured by NOF Corporation)).

<Color difference measurement>

The hue of each sample before and after heating was measured using a spectrophotometer (manufactured by X-Rite Corporation, product name SpectroEye). The measurement is performed with a light source D65, no light source filter, and a viewing angle of 2°. A piece of the sample is placed on an ISO whiteness 92% paper, and the measurement part of the spectrophotometer is pressed on it.

The measurement was repeated at 5 locations, and the average value was used for analysis. L ^* , a ^* , b ^* are directly measured values, and △L ^* , △a ^* , △b ^* are calculated by subtracting the value after heating to change the color.

There are various evaluation and classification systems for hue evaluation, but the CIELab color system is the color system established by CIE (International Commission on Illumination), based on JIS Z 8781-4 and ISO 116464-4. Because it is similar to human perception, it is generally used. It is a convenient classification system that can digitize tones in three dimensions. In addition, L ^* represents lightness, a ^* represents blue to yellow, and b ^* represents the axis of blue-green to red-violet. The higher the value of L ^* , the brighter it is, and the closer a ^* and b ^{* are} to 0, the lower the saturation. For example, L ^* , a ^* , b ^* =100,0,0 is white, and 0,0,0 is black.

<Sensory Evaluation>

Twenty reviewers were asked to look at the paper samples before and after heating to investigate the appearance of the stains felt by the color tone. When the 20 reviewers answered that there were more than 11 people who saw the stain and were uncomfortable, the sample’s The appearance impression was judged to be ×, and when there were less than 11 people, the appearance impression of the sample was judged to be ○, and these results were used for analysis.

<Analysis>

No relationship can be found between the △L ^* , △a ^* , and △b ^* values before and after heating, and the quality of the appearance impression (Figures 3A to 3C).

It is impossible to estimate the quality of the paper hue after heating from a simple graph composed of the difference of hue monomer values. Therefore, the review uses the color difference value for discriminant analysis, and performs discriminant analysis for the relevance of complex factors. As a result, as follows, the ΔL ^* a ^* b ^* value, which can determine the appearance impression with a high probability of 96.2%, can be obtained as a function of the parameter. The P value of the discriminant is less than 0.001, which is very statistically significant. Generally speaking, the discriminant rate can be used for estimation as long as the discriminant rate exceeds 75%, so the discriminant rate is 96.2%, which means that it is almost completely inferred.

Discriminant score (y) y=-0.18×△L ^* +0.08×△a ^* +0.13×△b ^* -2.36 (1)

Discriminant score above 0.62: × (poor)

Discriminant score less than 0.62: ○ (good)

Equation (1) indicates that the appearance impression after heating is roughly determined by the color difference △L ^* a ^* b ^* between the paper sample before heating and the paper sample after heating. For example, the lower △L ^* , △a ^* , △ The higher the b ^* value, the higher the discrimination score. That is, the impression of the paper after heating is in a bad direction.

The summary results are shown in Figure 4.

In addition, the discriminant analysis system uses the discriminant analysis of the multivariate analysis of EXCEL Statistics Ver.2.15 manufactured by Bell Curve Co., Ltd., and analyzes under the following conditions.

(1) P value of increase and decrease method: 0.2 to remove 0.2

(2) Remove the linear combination of variables for analysis

Figure 5 shows the relationship between △a ^* and △b ^* of the paper samples of this survey for more detailed explanation.

Since it cannot be displayed clearly in three dimensions, the value of △L ^* is binarized with -10 for convenience, and the value lower than -10 (becomes darker) is indicated by a black circle or a bold ×.

In the evaluation, those with poor appearance impression are indicated by "×", and the values of △a ^* and △b ^{* are} all located in higher positions. It means that the color changes in the direction of red-purple or yellow, or the fusion of the two brown colors by heating. In addition, △L ^{* is} relatively more common in lower ones. That is, these samples are visually close to the so-called light brown to dark brown sample group, and can be understood as a group with a poor appearance impression intuitively.

The L ^* value of these sample groups before heating is higher, and the a ^* value and b ^* value are also low, that is, they are mostly bright and low chroma. Such a low-brightness hue sample can easily change the brown color caused by heating and obtain a poor appearance impression.

On the contrary, the samples with good appearance impression "○" have low values of △a ^* and △b ^* . It means that the color changes in the direction of blue or green, or the blue-green fusion of the two by heating. Among them, the value of △L ^* is relatively low, that is, even though the brightness is small and dark, ○ can be seen. In these sample groups, contrary to the case of ×, the L ^* value before heating is low, and the a ^* value and b ^* value are also high, that is, most of the dark colors have high chroma. For such a sample with a darker hue, it is estimated that the change caused by heating is not obvious, so a good appearance impression is obtained.

If you look at the dot diagram as a whole, since Δa ^{* is} in a wide range of ±20 and Δb ^* is distributed in a wide range of ±30, it can be seen that the experiment is not only part, but includes samples with various hue changes.

The present invention focuses on the degree of color change before and after heating of the paper, and grasps this area as a numerical value to determine the effective range.

The parameterization as originally imagined can be easily understood as simply setting the range of hue before heating, but in this statistical method, the L ^* , a ^* , and b ^* values of the paper before heating cannot be obtained without color difference. Useful mathematical formula. It is because the colored components such as pigments or dyes contained in the colors have different thermal decomposition behaviors, so the degree of discoloration of each color component after heating is also different. Therefore, not only the color of the original paper, but also the degree of discoloration can accurately estimate the appearance impression of the present invention is reasonable.
