Description

  The present invention relates to a degreased paper. More specifically, the present invention relates to a degreased paper used for wiping off sebum and sweat that has been raised on the surface of the skin (skin).

  The human face, especially the nose, forehead, and eyebrows, has a strong sebum secretion. When sebum is secreted, the face becomes sticky or irritated. If sebum adheres to the face, makeup rides worsen, causing makeup to collapse. Sebum can be removed by washing the face. However, it is practically difficult to wash the face as needed when away from home. Therefore, a degreased paper that can easily remove the raised sebum has been widely used. In particular, in recent years, awareness of keeping skin clean regardless of gender has increased, and degreased paper has been widely used in general.

  As the degreased paper as described above, a paper obtained by cutting a foil-foiled paper used to stretch a gold foil into small pieces has been used in the past. The foil punched paper is soft to the touch because it is struck to such an extent that its fibers are crushed, thereby providing flexibility and smoothness. Furthermore, since the foil punched paper becomes transparent by absorbing a small amount of sebum that has floated on the skin, it has a feature (visibility) that the effect of removing the sebum can be visually confirmed.

  As can be understood from the characteristics of the foil-foiled paper, the quality generally required for the degreased paper is to have the visibility that makes the user recognize that the sebum has been absorbed, as well as the flexibility and the touch. is there. Furthermore, as described above, user needs are diversified with the recent increase in demand for degreasing paper. Thus, for example, a degreased paper with improved visibility has been proposed.

  For example, Patent Document 1 discloses a degreased paper obtained by laminating a white or colored colored layer and a fat absorbing layer (oil absorbing layer) that has a hue different from that of the colored layer and is made transparent by oil absorbing (oil absorbing). (Oil and grease wiping paper-like body) is disclosed. When this oil-absorbing paper absorbs oil, the surface of the oil-absorbing layer becomes transparent and the color of the colored layer placed underneath appears. Therefore, even if a small amount of sebum is wiped off, it is visually confirmed. can do.

Japanese Utility Model Publication No. 50-44712

  However, the degreased paper disclosed in Patent Document 1 has been proposed with the intention that the user can visually confirm even when a small amount of sebum has adhered. Therefore, the amount of sebum absorbed is not taken into consideration, and even when a small amount of sebum adheres, the oil-absorbing layer becomes transparent and the color of the colored layer located below is developed. However, the amount of sebum on the skin varies depending on the user. Even the same user may have different amounts of sebum depending on the season and environment. Therefore, if the oil-absorbing layer is made transparent with a small amount of sebum so that it can be reliably detected that the oil has been absorbed like the degreased paper of Patent Document 1, the total amount of oil absorption ( The fat absorption capacity) is inferior. Therefore, even if the oil-absorbing layer is transparent and the colored layer appears on the entire surface, the sebum cannot be wiped off when used by a user having a large amount of sebum. For this reason, it is necessary to wipe off the sebum that has come out on the skin many times, and the number of sheets used for the oil removing paper increases, which is uneconomical.

  Therefore, the object of the present invention is to make it possible for the user to sufficiently visually confirm even when the amount of sebum to be wiped is small, and to reliably wipe it off even when the amount of sebum being wiped off is large. It is to provide a paper.

The above-mentioned object is a sheet-like base material, and a colored first oil-absorbing layer provided by applying a coating liquid containing a colorant, a fat-absorbing filler and a binder on at least one surface of the sheet-like base material, Including a second oil-absorbing layer that is provided by applying a coating liquid containing a fat-absorbing filler and a binder on the first oil-absorbing layer and changes from an opaque state to a transparent state when the oil is absorbed. It can be achieved by a degreased paper characterized by

  According to the present invention, when the second absorbent layer absorbs oil, it changes from an opaque state to a transparent state, so that the color of the lower first absorbent layer is developed. Therefore, the user can visually confirm if the second oil-absorbing layer is adjusted so as to be transparent when a small amount of sebum is absorbed by adjusting the oil-absorbing ability. On the other hand, since the 1st oil absorption layer located in the lower side of the 2nd oil absorption layer is equipped with oil absorption capability, it can cope also when there is much sebum to wipe off.

  Furthermore, it is good also as a structure where the said sheet-like base material is provided with oil absorption. Thus, if the sheet-like base material also has a fat-absorbing property, it can be made a degreased paper that can absorb a large amount of sebum more reliably. In addition, the sheet-like base material itself may be provided with an oil-absorbing property, or by adding an oil-absorbing filler, the sheet-like base material is given an oil-absorbing property or increases the oil-absorbing property. It may be.

  Moreover, it is preferable that a said 1st oil absorption layer contains a dark colorant. Such a dark colorant is preferably selected from, for example, black, blue, red, and green. If the first oil-absorbing layer is a dark color, the user can be surely visually recognized when the second oil-absorbing layer is transparent.

  Moreover, the said 2nd fat absorption layer shall contain the filler which is a low refractive index with respect to light. As such fillers, for example, inorganic fillers such as clay, talc, kaolin, calcium carbonate, and amorphous silica, and fine particles of organic pigments such as plastic pigments can be employed. These fillers can be used alone or in appropriate combination.

  Moreover, it is preferable that the hues of the first and second absorbent layers are different. If the hue of the second oil-absorbing layer is different from the hue of the dark-colored first oil-absorbing layer, the user can more reliably visually recognize the second oil-absorbing layer when it is transparent.

  And the said 1st oil absorption layer may set the oil absorption capability larger than the said 2nd oil absorption layer. If comprised in this way, when the amount of sebum to wipe off is large, sebum can be reliably absorbed with a 1st oil absorption layer.

  According to the present invention, there is provided a degreased paper that can be visually confirmed by the user even when the amount of sebum to be wiped off is small, and can be wiped off even when the amount of sebum is wiped off. Can be provided.

  Hereinafter, a degreasing paper according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an enlarged view showing a configuration of a degreasing paper 1 according to the first embodiment. The degreased paper 1 includes a sheet-like base material 10, a first oil-absorbing layer 11 provided on the sheet-like base material 10, and a second oil-absorbing layer 12 further provided on the first oil-absorbing layer 11. Is included.

The sheet-like base material 10 is a thin and flexible sheet-like material, and more preferably has an oil-absorbing property. Such a sheet-like base material 10 can be formed by using, for example, wood pulp and non-wood pulp such as manila hemp and flax alone or by using a pulp raw material appropriately combining them. More specifically, round net pulp material, and paper making by using a Fourdrinier paper machine, forms a suitable sheet-like substrate 10 if the basis weight 12g ^/ m ² ~25g / m 2 of sheet can do. The sheet-like substrate 10 formed in this way has good processing suitability when the first absorbent layer 11 and the second absorbent layer 12 are provided. Moreover, after forming the absorbent layers 11 and 12 on the sheet-like base material 10 to obtain a degreased paper, it does not cause tearing or damage, and has moderate flexibility. Therefore, it can be set as the degreased paper excellent in the usability.

In addition, since the intensity | strength is too low if the basic weight of the said sheet-like base material 10 is less than 12 g / m < ² >, the workability at the time of forming the fat absorption layers 11 and 12 will be inferior. The manufactured degreased paper is easily broken or damaged when used. On the other hand, when the basis weight of the sheet-like substrate 10 exceeds 25 g / m ² , the suppleness of the sheet is lost, so that the feeling of use is lowered. You may add inorganic fillers, such as a talc, a kaolin, a calcium carbonate, a titanium oxide, to the said sheet-like base material 10 as needed. By adding such a filler, the oil-absorbing ability of the sheet-like substrate 10 can be enhanced.

  On the said sheet-like base material 10, the 1st oil absorption layer 11 and the 2nd oil absorption layer are laminated | stacked in order. For example, preparing the coating paper for forming the 1st oil absorption layer 11 and the 2nd oil absorption layer 12 previously, and manufacturing the grease removing paper 1 by apply | coating this on the sheet-like base material 10 in order. Can do. The first oil-absorbing layer 11 is a colored oil-absorbing layer. On the first oil-absorbing layer 11, a second oil-absorbing layer 12 that is opaque and transparent when absorbed is formed.

  The first absorbent layer 11 is formed including a colorant and a absorbent material. The colorant employed here is a dark color such as black, blue, red, or green so that the user can visually confirm the color when the second absorbent layer 12 becomes transparent. It is desirable. These dark colorants can be the same as those conventionally added to paper. The method for coloring the first absorbent layer 11 is not particularly limited, and a commercially available coloring dye or coloring pigment may be contained in the coating liquid. Moreover, the 1st oil absorption layer 11 is added with the filler excellent in the capability (absorbency) to absorb sebum. As such a fat-absorbing filler, for example, inorganic fillers such as clay, talc, kaolin, calcium carbonate, titanium dioxide, and amorphous silica, and fine particles of organic pigments such as plastic pigments can be suitably used. By providing these fillers on the surface of the sheet-like substrate 10, the amount of sebum absorbed and the absorption rate of the oil removing paper 1 can be increased.

  The coating liquid for forming the first absorbent layer 11 is formed by the above-described colorant, filler, and binder that fixes these to the sheet-like substrate 10. Any binder may be used as long as it can fix the colorant and the absorbent filler to the sheet-like substrate 10. As the binder having this function, for example, a latex such as NBR or SBR, an emulsion such as vinyl acetate, EVA, acrylic or urethane, or a water-soluble polymer such as carboxymethyl cellulose can be employed. The amount of the binder component contained in the first absorbent layer 11 is preferably in the range of 5 to 40% in terms of solid content with respect to the filler. If the amount of the binder component is less than 5%, the filler may fall off from the sheet-like substrate 10, while if it exceeds 40%, the effect of increasing the amount of sebum absorbed and the absorption rate by the filler will be hindered. Therefore, there exists a possibility that sufficient oil absorption as a degreasing paper cannot be obtained. In addition, you may apply | coat the coating liquid containing an above-described coloring agent, a filler, and a binder on the sheet-like base material 10, and print the 1st fat absorbing layer 11 on the sheet-like base material 10 using a printing technique. May be.

The coating amount of the first oil-absorbing layer 11 on the sheet-like substrate 10 is desirably in the range of 3 to ²⁰ g / m ² from the viewpoint of sebum absorbability and proper processing. When the application amount of the first oil absorbing layer 11 is less than 3 g / m ² , the oil absorbency of sebum is reduced. In addition, when the coating amount exceeds 20 g / m ² , it becomes difficult to stably coat the sheet-like substrate 10.

  Furthermore, the 2nd oil absorption layer 12 formed on the 1st oil absorption layer 11 is demonstrated. The 2nd oil absorption layer 12 has the opaqueness of the grade which can conceal the color which the 1st oil absorption layer 11 has at least. In addition, it is desirable that the hue is different from that of the first absorbent layer 11. For example, the second absorbent layer 12 is preferably white (uncolored) or a light color with a hue different from that of the first absorbent layer 11. This 2nd oil absorption layer 12 is comprised so that the color of the 1st oil absorption layer 11 currently transparentized by absorbing sebum, and being colored by it may express. Furthermore, by setting the first oil absorbing layer 11 and the second oil absorbing layer 12 to different hues, the contrast can be further increased and a visual effect can be given to the user.

  The 2nd fat absorption layer 12 is opaque before fat absorption, and is comprised so that it may become transparent by fat absorption. Therefore, the second absorbent layer 12 includes, for example, inorganic fillers such as clay, talc, kaolin, calcium carbonate, and amorphous silica, and fine particles of organic pigments such as plastic pigments. These fillers are oil-absorbing. Further, these fillers have a low refractive index of 1.4 to 1.7 with respect to light. For example, kaolin has a refractive index of 1.55 to 1.6, calcium carbonate has a refractive index of 1.48 to 1.66, and amorphous silica has a refractive index of about 1.45. When sebum permeates between the particle surfaces of these fillers and between the particles, scattered light is reduced on the particle surfaces and the like, and the filler becomes transparent. That is, the second oil absorbing layer 12 becomes transparent when the oil is absorbed. Thereby, since the dark color of the 1st oil absorption layer 11 will express, a high visual effect will be exhibited about the part which absorbed oil.

  Furthermore, fillers such as clay, talc, kaolin and calcium carbonate are generally white or grayish white. Accordingly, since the second absorbent layer 12 can be made opaque white by including a certain amount of such filler, the first absorbent layer colored in dark black, blue, red, green, etc. A hue different from 11 can be easily set. The second absorbent layer 12 may be set to be white as described above, but may be lightly colored using a small amount of a colorant having a hue different from the color adopted in the first absorbent layer 11. The clay, talc, kaolin, calcium carbonate, etc. are fillers that are also added to cosmetics, etc., and by providing these on the surface of the degreased paper, not only the amount of sebum absorbed and the absorption rate are increased, but also the surface It is also possible to obtain the effect of smoothing and improving the touch.

As for the coating liquid for forming the second absorbent layer 12, a latex such as NBR or SBR, an emulsion such as vinyl acetate, EVA, acrylic or urethane, or a water-soluble polymer such as carboxymethyl cellulose is used as a binder. Can do. The binder is preferably in the range of 5 to 40% in solid content with respect to the filler. This is the same as the coating liquid for the first absorbent layer 11. The coating amount of the second oil-absorbing layer is preferably in the range of 5 to 15 g / m ² from the viewpoint of ensuring sebum absorbability and visibility during oil absorption. When the coating amount of the second absorbent layer is less than 5 g / m ² , the concealing property of the first absorbent layer 11 is lowered and the visibility is deteriorated. Moreover, when the coating amount of the second oil absorbing layer 12 exceeds 15 g / m ² , when the oil absorbing amount is small, the inorganic filler or the like is not sufficiently transparent, and the contrast with the hue of the first oil absorbing layer 11 or the like. The visual effect due to is attenuated. The more preferable coating amount of the second oil absorbing layer is 8 to 12 g / m ² .

  In the degreased paper 1 having the above configuration shown in FIG. 1, the light LT is irregularly reflected on the surface by the second absorbent layer 12 located on the surface before the oil absorption, and the reflected light RE-1 It becomes. Therefore, the color of the colored first absorbent layer 11 is concealed by the second absorbent layer 12. At this time, the user is in a state of looking at the white color of the second absorbent layer 12 or the like. On the other hand, since the second absorbent layer 12 becomes transparent when the absorbent paper 1 absorbs oil, the light LT becomes reflected light RE-2 reflected from the surface of the colored first absorbent layer 11. At this time, the user changes to a state of viewing the dark black, blue, red, green, etc. of the first absorbent layer 11. In this way, the user can visually confirm that the sebum of the skin has been wiped off by the color change of the grease removing paper 1.

  Here, the filler content and the coating amount of the second oil-absorbing layer 12 can be adjusted as appropriate within the above-described ranges, and can be made transparent from an opaque state with a relatively small amount of sebum. Therefore, the grease removing paper 1 can obtain a sufficient visual effect even when the amount of sebum to be wiped off is small. Further, in the degreased paper 1, the first absorbent layer 11 and the sheet-like base material 10 located under the second absorbent layer 12 have a grease absorbing capability. That is, as illustrated in FIG. 1, the oil absorbing region 20 is expanded to the first oil absorbing layer 11 and the sheet-like base material 10. Since the absorbent paper 1 has a multi-layered absorbent layer as described above, when the amount of sebum is large, it can be reliably absorbed by the absorbent layer located under the second absorbent layer 12. Therefore, even when the oil removing paper 1 has a large amount of sebum, the oil can be sufficiently wiped off by one wiping.

  For example, you may employ | adopt the structure which set the oil absorption capability of the 1st oil absorption layer 11 larger than the oil absorption capability of the 2nd oil absorption layer 12. FIG. In this case, the opaqueness of the 2nd fat absorption layer 12 is ensured, and filler content and a coating amount are suppressed. On the other hand, the filler content and the coating amount of the first oil-absorbing layer 11 located on the lower side are increased to improve the oil-absorbing ability. If it does in this way, the 2nd oil absorption layer 12 can be clarified rapidly with a small amount of sebum. And the degreased paper which can absorb sebum reliably by the 1st oil absorption layer 11 can be formed.

  As is clear from the above description, since the second absorbent layer 12 becomes transparent even when the wiped paper 1 has a small amount of sebum wiped off, the user is absorbed by the change in color. I can confirm that. Moreover, since this oil-absorbing paper 1 can set a fat absorbing capacity large, even when there are many amounts of sebum, it can absorb reliably. Therefore, it is economical because it is possible to suppress an increase in the number of used sheets as in the prior art. Therefore, the degreased paper 1 of the present embodiment is excellent in visibility and oil-absorbing ability, and can be provided as an economical degreased paper.

  FIG. 2 is an enlarged view showing the configuration of the degreasing paper 2 according to the second embodiment. Although the degreasing paper 1 of 1st Embodiment shown in FIG. 1 was the structure which provided the 1st oil absorption layer 11 and the 2nd oil absorption layer 12 only on the single side | surface of the sheet-like base material 10, The degreased paper 2 shown by 2 is provided with a first absorbent layer 11 and a second absorbent layer 12 on both surfaces of a sheet-like substrate 10. In addition, the 1st oil absorption layer 11-1 and the 2nd oil absorption layer 12-1 are provided in the surface side, and the 1st oil absorption layer 11-2 and the 2nd oil absorption layer 12-2 are provided in the back surface side. Yes.

  Since the degreasing paper 2 has a double-sided configuration, it is more economical than the degreasing paper 1. In addition, the 1st fat absorbing layer 11 and the 2nd fat absorbing layer 12 of the front and back may be formed with the same structure, and may be formed with a different structure. In the case of different configurations, for example, if the coloring of the first absorbent layer 11-1 on the front side is changed to red and the coloring of the first absorbent layer 11-2 on the rear side is changed to blue, the user's eyes Can be entertained. Further, for example, if the user is prompted to use the front surface first and then the back surface, the change in the amount of sebum wiped by the user can be confirmed.

  Further, FIGS. 3A and 3B are diagrams showing a modified example of the degreased paper 1. FIG. 3A shows a degreasing paper 3 as a first modification. As for this degreasing paper 3, the 1st oil absorption layer 11-2 colored on the back surface side is exposed. In this case, the back side is colored from the beginning, but since it can be used for wiping off sebum, it is more economical than the degreasing paper 1 of FIG. FIG. 3B shows a degreased paper 4 as a second modification. This degreasing paper 4 is provided with a second absorbent layer 12-2 that changes from an opaque state to a transparent state when it is absorbed on the back side. In this case, the color appears on the sheet-like base material 10 when the back side changes. If the hues of the second oil-absorbing layer 12-2 and the sheet-like substrate 10 are different, there is a color change as in the case of the surface side, so that the user can confirm the absorption of sebum. Since this degreased paper 4 can also be used for wiping off sebum on the back side, it is more economical than the degreased paper 1 in FIG.

  In the following, cosmetic degreased paper manufactured as an example according to the present invention will be described. In addition, about the raw material shown below, all compounding is shown by the weight part.

After 80 parts of papermaking NBKP and 20 parts of flax pulp were dispersed in water as the sheet-like substrate 10 and beaten, a base paper having a basis weight of 20 g / m ² was obtained using a long mesh multi-cylinder paper machine.

Application of the first absorbent layer 11 Next, 20 parts of kaolin, 10 parts of calcium carbonate, 4 parts of acrylic emulsion (Polysol M-19 manufactured by Showa Takabun Co., Ltd.), 2 parts of black pigment (TOA black AM1000 manufactured by Toa Kasei Co., Ltd.) Was dispersed in water to prepare a coating solution. This coating solution was applied to a base paper using a Meyer bar so that the solid content was 6 g / m ² and further dried.

Application of Second Absorbent Layer 12 Further, 20 parts of kaolin, 10 parts of calcium carbonate, and 4 parts of an acrylic emulsion (Polysol M-19 manufactured by Showa Polymer Co., Ltd.) were dispersed in water to prepare a coating solution. The coating liquid was coated and dried in the same manner as in the case of the first absorbent layer 11 by using a Meyer bar as the base paper so that the solid content coating amount was 11 g / m ^2. A degreased paper for cosmetics was obtained.

Except for changing the black pigment of the first absorbent layer 11 in Example 1 to a red pigment (TB720Red2B, manufactured by Dainichi Seika Kogyo Co., Ltd.) and changing the coating amount of the second absorbent layer 12 to 8 g / m ^2. The cosmetic degreased paper of Example 2 was obtained in the same manner as in Example 1.

A cosmetic degreased paper of Example 3 was obtained in the same manner as in Example 1 except that 1 part of red pigment was added to the second absorbent layer 12 and the coating amount was changed to 12 g / m ² .

The makeup of Example 4 is the same as Example 1 except that the coating amount of the first absorbent layer 11 is 3 g / m ² and the coating amount of the second absorbent layer 12 is changed to 5 g / m ^2. A degreased paper was obtained.

Furthermore, in order to confirm the visibility and the oil-absorbing ability of the degreased papers of Examples 1 to 4, the degreased papers of Comparative Examples 1 and 2 below were produced.
(Comparative Example 1)
The cosmetic fat of Comparative Example 1 as in Example 1, except that the black ink was applied in an amount of 3 g / m ² using an RI printing tester instead of the first absorbent layer 11. I got a paper. In Comparative Example 1, the middle layer corresponding to the first oil-absorbing layer is black ink and does not have oil-absorbing properties.

(Comparative Example 2)
A degreased paper of Comparative Example 2 was obtained in the same manner as Comparative Example 1 except that the coating amount of the second absorbent layer 12 was changed to 18 g / m ² . That is, in Comparative Example 2, the second absorbent layer 12 on the surface is formed thicker than the degreased paper of Comparative Example 1.

(Comparative Example 3)
Disperse 20 parts of kaolin, 10 parts of calcium carbonate, 4 parts of acrylic emulsion (Polysol M-19 manufactured by Showa Polymer Co., Ltd.), 0.1 part of red pigment (TB720 Red 2b manufactured by Dainichi Seika Kogyo Co., Ltd.) in water. A coating solution was prepared. This coating solution was applied to the same base paper as in Example 1 using a Meyer bar so that the solid content coating amount was 18 g / m ² , and further dried to make the degreasing cosmetic for Comparative Example 3 I got paper. Comparative Example 3 has a configuration in which a colored absorbent layer is provided on a base paper, and has the same configuration as a conventional product.

  Each of the above degreased papers was evaluated by the following test method and sensory evaluation by three testers A, B, and C having different amounts of sebum. The basis weight was measured according to JIS P8124. Moreover, the measurement of the application quantity of the 1st oil absorption layer 11 and the 2nd oil absorption layer 12 was computed from the basic weight difference before and behind application | coating. The brightness L was measured using SM color computer SM-4 (manufactured by Suga Test Machine Co., Ltd.). The lightness change ΔL was calculated from the lightness difference before and after the pseudo sebum transfer.

  The transfer test of pseudo sebum uses a RI-3 type printability tester (manufactured by Ishikawajima Sangyo Co., Ltd.) and uses a mixed oil of castor oil: benzyl alcohol = 80: 20 as pseudo sebum, and the transfer amount to paper is a predetermined amount. Then, the artificial sebum was applied to the printing roll and transferred.

  FIG. 4 is a table summarizing the evaluation results of the degreased papers of Examples 1 to 4 and Comparative Examples 1 and 2. This will be described with reference to FIG. In FIG. 4, “◎” indicates an excellent evaluation, “◯” indicates a good evaluation, “Δ” indicates an acceptable evaluation, and “×” indicates an inappropriate evaluation. Also, the surface layer in FIG. 4 corresponds to the second absorbent layer 12, the intermediate layer corresponds to the first absorbent layer 11, and the substrate corresponds to the sheet-like substrate 10. The degreased papers of Examples 1 to 3 have a visual effect that is higher than that of conventional products even when used by a tester with a small amount of sebum. It was evaluated that it could be removed. In addition, it was possible to prevent stickiness and shining on the face. In addition, although the degreased paper of Example 4 is a thing which suppressed the coating amount of the oil-absorbing layer from the degreased paper of another Example, it is favorable in evaluation of the testers A and B whose sebum amount is below a standard. Results were obtained. When tester C with a large amount of sebum was used, it was evaluated that the sticky feeling remained slightly on the face, but it was confirmed that the sebum can be sufficiently removed by wiping once.

  On the other hand, the degreased paper of Comparative Example 1 was evaluated as having a visual effect with less stickiness of the face in the testers A and B having a sebum amount below the standard amount. However, Tester C with a large amount of sebum obtained an evaluation that the sebum could not be removed sufficiently and stickiness remained on the face. In addition, the test sample A having a small amount of sebum can be used for the degreased paper of Comparative Example 2 even when the sebum can actually be wiped off, even when the evaluation of the visual effect is low and the sebum can be absorbed. Was not obtained. Although the visual effect can be obtained by suppressing the coating amount of the second absorbent layer 12 located on the surface from the comparative examples 1 and 2, it cannot be applied when the amount of sebum is large, and the coated amount of the second absorbent layer 12 It can be seen that a positive visual effect cannot be obtained when a small amount of oil is absorbed when the amount is increased. Furthermore, the degreased paper of Comparative Example 3 was evaluated as having a visual effect with less stickiness of the face in the tester C having a large amount of sebum. However, the tester A with a small amount of sebum was evaluated as having poor visual effects. In Tester C having a large amount of sebum, the degreased paper of Comparative Example 2 is inferior in terms of the stickiness of the face as compared with the degreased paper of Comparative Example 3, and the middle layer is a black ink layer. It was confirmed that the sebum absorption was inhibited more than when no intermediate layer was provided.

In the transfer test of pseudo sebum, the lightness change ΔL when the transfer amount of the pseudo sebum was 0.75 g / m ² was 8 to 19 for the degreased papers of Examples 1 to 4, and It was confirmed that the change in brightness was large compared to the case. This can be understood as supporting data that the user can visually recognize the oil removing paper of Examples 1 to 4 even when relatively small amount of sebum is absorbed. In addition, when the transfer amount of pseudo sebum is increased to 3 g / m ² , the change in lightness ΔL increases. This indicates that transparency is increased by fully absorbing sebum. It can be understood that the degreased papers of the examples show that they have sufficient oil absorbing ability. FIG. 5 collectively shows the relationship between the degreasing paper of the example according to the present invention and the degreasing paper of the comparative example. As shown in FIG. 5, the degreased papers of Examples 1 to 4 are excellent in visibility and the ability to absorb oil, and thus can be provided as commercial degreased papers that meet the user's requirements.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.
