Description

  The present invention relates to a sheet-like cosmetic sample for laminating a solid cosmetic such as a foundation on a base sheet by screen printing and distributing it as a sample. More specifically, the present invention relates to a cosmetic sample that has almost no omission of the cosmetic layer when the cosmetic is scraped off with a puff during use. Furthermore, the present invention relates to a cosmetic sample that is laminated with a cosmetic corresponding to 4 to 5 trials.

Most of the cosmetic samples were equivalent to one trial. In addition, a cosmetic provided with a cosmetic layer corresponding to the trial amount for 2 to 3 times by repeatedly printing screen printing several times on the surface of the polyester film having a specific surface roughness subjected to the roughening treatment A sample has been developed (Patent Document 1).
JP 2002-58528 A

  However, the above-described conventional samples can be used without any problem in the normal usage method, but if the consumer scrapes off more than usual, a part of the cosmetic layer may fall off, which is an improvement. Was requested. In addition, in order to enhance the recognition effect of a product with a strong impression of the trial effect, provision of a free sample in which a cosmetic layer corresponding to 4 to 5 doses is formed is also strongly demanded.

The cosmetic layer formed by screen printing is provided with 50 to 100 mg (30 to 60 g / m ² as the coating amount) provided in the sample as a trial for one time when the printing area of the foundation is a rectangle of 49 mm × 34 mm. 150 mg (approx. 90 g / m ² ) for ² doses, 200 mg (approx. 120 g / m ² ) for 3 doses, 250 mg (approx. 150 g / m ² ) for 4 doses, 300 mg (approx. 180 g / m) for 5 doses ² ) The above is expected.

In order to laminate a large amount of cosmetic layer corresponding to 4 to 5 doses, a conventional screen plate for applying a relatively small amount of conventionally used polyester film having a specific surface roughness as described above is used. When it was attempted to perform overprinting, the coating amount could not be increased unless the printing pressure was lowered. For this reason, when the printing pressure is lowered, there is a problem that the dropout during the production process is remarkably increased and the production is impossible. On the other hand, if the printing pressure is increased to such an extent that the drop-off can be reduced, the coating amount decreases, and there is a problem that the necessary coating amount cannot be obtained even if the number of times of printing is repeated four times or more, and the production cannot be performed.

  Therefore, there has been no method for providing cosmetics corresponding to 4 to 5 doses, other than using a filling method in which cosmetics are packed into a small container and compressed.

  In order to obtain a high coating amount, in the screen printing, a thick film screen printing in which the photosensitive resin film is extremely thick as 50 μm to 1 mm is used as compared with the usual 10 μm. Even when ink is used, only the peripheral portion of the solid printing is printed with a particularly thick thickness, so that it is suitable for a pattern composed of lines and dots, but not suitable for solid printing. When printing solid using a coating solution consisting of a foundation and a solvent, such as a cosmetic sample, the problem is that in one printing, the peripheral edge of the printing is reversed due to poor transfer, and the coating amount cannot be secured. was there.

  Therefore, the present invention is intended to solve the above-described problem, and the peripheral layer due to omission of cosmetics or poor transfer during the manufacturing process despite the fact that the cosmetic layer corresponding to 4 to 5 times is laminated. It is an object of the present invention to provide a cosmetic sample that has almost no missing part and that does not cause the cosmetic layer to fall off even if the sample is strongly scraped off with a puff when the sample is used.

  When applying a cosmetic such as a foundation, the present inventors have not been able to eliminate a loss due to a transfer defect during printing, so even a thick film screen printing plate that could not be used conventionally is a normal one. It has been found that by performing multiple printing in the same manner as when using a printing plate, omission due to poor transfer is eliminated and the coating amount can be significantly increased. In addition, by removing the printing by using the thick film screen printing plate at least twice, the omission due to the transfer failure of the peripheral portion is eliminated, and the application amount is steadily increased by further increasing the number of times, and the smoothness of the peripheral portion is further increased. It has been found that the desired coating amount can be obtained.

  Furthermore, by applying printing using the thick film screen printing plate to the surface of the base material having a specific surface roughness, the falling off of the cosmetic during the manufacturing process is eliminated, and the puff is strongly used when the sample is used. The present inventors have found that the cosmetic layer does not fall off even if scraped off.

  The cosmetic sample according to the present invention includes a base sheet, a protective sheet having an opening at which the surface of the cosmetic layer is exposed and laminated on the surface of the base sheet, and a coating laminated on the other surface of the protective sheet. In a cosmetic sample in which a cosmetic layer is laminated on the surface of a base sheet in a sealed space formed by a film layer, the cosmetic layer is measured with a stylus type surface roughness measuring instrument stipulated in JIS B0651. In addition, according to the method described in JIS B0601, the substrate sheet having a surface roughness of a center line average roughness of 3.5 to 10 μm is laminated by printing using a thick film screen printing plate. To do.

  Furthermore, the present invention includes a configuration in which the cosmetic layer uses a slurry composed of a cosmetic and a solvent, and printing using a thick film screen printing plate is repeated at least twice.

  In the present invention, since printing using a thick film screen printing plate is repeated twice or more, omission due to poor transfer at the peripheral portion can be eliminated, the peripheral portion of the cosmetic layer becomes smooth, and the coating amount is greatly increased. be able to. Overprinting is different from sliding a squeegee a plurality of times in a single printing, in which printing is repeated after a cosmetic layer once wet is formed on the surface of the base sheet. Even if the squeegee is slid a plurality of times in one printing, it is not possible to eliminate the omission due to poor transfer at the peripheral edge. In the present invention, two times of printing performed twice are referred to as two times overprinting, three times overprinting is referred to as three times overprinting, and four times overprinting is referred to as four times overprinting.

  The cosmetic layer of the cosmetic sample of the present invention is laminated on the surface of the cosmetic receiving layer having a surface roughness of 3.5 to 10 μm centerline average roughness formed on the surface of the base sheet. It is a feature.

  Thus, the base material sheet used for the cosmetic sample of the present invention is a polycarbonate film having a surface roughness with a centerline average roughness of 3.5 to 10 μm, and a cosmetic layer is directly laminated on the surface thereof. It is characterized by.

  Since it is laminated on the surface having a center line average roughness of 3.5 to 10 μm, the adhesion with the cosmetic layer is increased, it can be prevented from falling off in the production process, and the cosmetic layer can be used when the sample is used. Dropping is eliminated.

  In addition, the printing pressure can be increased as compared with the case where a high coating amount is obtained using a normal screen printing plate, so that the cosmetic layer can be formed firmly, and can be prevented from falling off during the manufacturing process. Even when scraping strongly, the cosmetic layer will not fall off, improving the sense of removal during user use.

  The thick film screen printing plate used when forming the cosmetic layer of the cosmetic sample of the present invention is characterized in that a photosensitive resin film having a thickness of 100 to 400 μm is added to a 30 to 100 mesh screen. Is. The thickness of the photosensitive resin film is determined in consideration of the balance between the number of printings and the target application amount.

  As the screen mesh of the thick film screen printing plate used in the present invention, 30 to 100 mesh can be used, preferably 35 to 80 mesh, more preferably 40 to 60 mesh. If it exceeds 100 meshes, it is difficult to eliminate omission due to transfer failure, which is not preferable. Printing using a thick-film screen printing plate such as the mesh range described above is preferable because the cosmetic layer can be formed firmly, and can be prevented from falling off in the manufacturing process. In particular, when a screen of 60 mesh or less is used, it is preferable that a clear mesh pattern is exhibited on the entire surface of the applied cosmetic layer, resulting in a design effect.

  If the number of times of printing is 2 times or more, there is no particular problem, preferably 3 times, and the appearance of the cosmetic layer surface is improved by 3 times of printing, and a clear mesh pattern is exhibited on the entire surface. In consideration of efficiency, it is preferable to finish the process up to four times. When overprinting, for example, it is possible to print under the same conditions using a single printing machine, for example, printing with two or more printing machines using the same mesh screen, or using different mesh screens. It is also possible to use it for overprinting. In addition, when printing is performed 3 times or more, it is possible to make the mesh pattern on the surface of the cosmetic layer inconspicuous by using a screen printing plate of the last printing having a mesh size exceeding 60 mesh.

  In addition, when performing overprinting, it is necessary to repeat the next printing while the surface of the layer printed previously is wet with the solvent. When the solvent on the surface of the previously printed layer is volatilized and the next printing is repeated after the surface is dried, the surface of the previous printing layer is transferred to the screen printing plate and the overprinting becomes impossible. If the interval from the previous printing to the next printing is 3 seconds to 1 minute, the solvent on the surface will not be volatilized, so the next printing can be repeated. This interval is preferably within 30 seconds, and more preferably within 10 seconds.

  Any known volatile solvent can be used for slurrying the cosmetic so that it can be screen-printed. For example, lower alcohols such as ethyl alcohol and isopropyl alcohol, low-boiling hydrocarbons, low-boiling silicone oils, Examples include cyclic silicone, water, or a mixture thereof. The mixing ratio is appropriately adjusted according to the composition of cosmetics and printing conditions.

  Next, it was confirmed that printing failure was improved by the number of times of overprinting when a thick film screen printing plate was used.

  (Experimental Example 1) Using isopropyl alcohol as a solvent, foundation C was diluted to a mass concentration of 58% to prepare a slurry, and a biaxially stretched polyester film (trade name Lumirror E125D20 manufactured by Toray Industries, Inc.) Using a 40-mesh thick film screen printing plate (resin film thickness 300 μm) (surface roughness 1.2 μm), printing was repeated three times with a printing area of 34 mm × 49 mm, and the state of the printed surface was observed every number of times. Table 1 shows the observation of the printed surface and the coating amount. The case where there was no omission in printing at the peripheral edge due to poor transfer was indicated as ◯, the case where there was a slight omission as Δ, and the case where there were many omissions as x. As for the mesh pattern, a clear pattern was marked with ◯, a partially visible pattern was marked with Δ, and a printed surface was poor and could not be evaluated with x.

厚膜スクリーン印刷版を用いた１回印刷では転移不良による周縁部の印刷抜けが見られるが、２回印刷でそれが解消されている。３回重ね印刷によってメッシュパターンが明瞭になっている。

In the one-time printing using the thick film screen printing plate, printing omission at the peripheral portion due to the transfer failure is seen, but this is solved by the two-time printing. The mesh pattern is clarified by 3 times overprinting.

  Usually, cake-type foundations used in a compact form are obtained by compressing and solidifying a pigment whose surface has been treated with oil, a surfactant or the like. Even in a sample manufactured by screen printing as in the present invention, a solvent is used but a component having a substantially binding force is not included, so that a layer having a high coating amount as described above is screen-printed on a base sheet. When trying to laminate, the problem that the desired coating amount cannot be obtained with a normal screen printing plate can be solved by using a thick film screen printing plate, but it can usually be obtained by sandblasting etc. A new problem arises in that a base sheet having a rough surface surface cannot be manufactured due to frequent dropping. Therefore, the following experiment was conducted in order to find an appropriate surface roughness having high adhesion to the cosmetic layer formed by screen printing.

  (Experimental example 2) Using a base sheet having a surface roughness with a center line average roughness in the range of 1.2 to 11.1 µm, three times with different oil content using a thick film screen printing plate three times Overprinting was performed, and the degree of removal of the cosmetic layer when the cosmetic layer was scraped and scraped off with a puff (hereinafter referred to as “feel”) was evaluated.

  (Preparation of base sheet having different surface roughness) Biaxially stretched polyester film (trade name Lumirror E125D20, manufactured by Toray Industries, Inc.) Sand mat processed product (surface roughness 1.2 μm) Used, printing was performed using a 60 mesh stainless screen printing plate having a coating area of 38 mm × 53 mm to prepare a base sheet having a surface roughness of 1.9 μm and 2.7 μm. Similarly, using the coating liquid shown in Table 3, printing was performed using a 100-mesh stainless screen printing plate having a coating area of 38 mm × 53 mm, and a base sheet having a surface roughness of 4.5 μm to 11.1 μm was produced. .

（化粧料シートの作製）イソプロピルアルコールを溶剤として使用し、表５に示す３種のファンデーションを各々質量濃度６５．５％、６０．０％、５８．０％に希釈してスラリーを調製し、先に準備しておいた表面粗さ１．２μｍ〜１１．１μｍの基材シートの表面にスクリーン印刷して化粧料層が積層された化粧料シートを作製した。通常版の場合は、ステンレス製６０メッシュスクリーン印刷版を用い、厚膜版の場合は、ステンレス製４０メッシュスクリーン印刷版（樹脂膜厚３００μｍ）を用いた。１つ当たりの印刷面積は３４ｍｍ×４９ｍｍ長方形で各々３回重ね印刷した。付着量は、通常版で１５０〜１８０ｍｇ、厚膜版で３００〜３２０ｍｇであった。

(Preparation of cosmetic sheet) Using isopropyl alcohol as a solvent, the three foundations shown in Table 5 were diluted to a mass concentration of 65.5%, 60.0%, and 58.0%, respectively, to prepare a slurry, A cosmetic sheet in which a cosmetic layer was laminated by screen printing on the surface of a base sheet having a surface roughness of 1.2 μm to 11.1 μm prepared in advance was prepared. In the case of the normal plate, a stainless steel 60 mesh screen printing plate was used, and in the case of the thick film plate, a stainless steel 40 mesh screen printing plate (resin film thickness 300 μm) was used. The printing area per one was a 34 mm × 49 mm rectangle, and each layer was printed three times. The adhesion amount was 150 to 180 mg for the normal version and 300 to 320 mg for the thick film version.

（化粧料シートの評価）［脱落試験］得られた化粧料シートを化粧料層を中心に９０ｍｍ角に裁断して脱落試験用片１５を作製した。図５に示すように幅２００ｍｍ長さ５００ｍｍ高さ８０ｍｍの鉄製ブロック２つをＬ型固定台１１に組み、一方のブロックに高さ測定用目盛１３を取り付け、もう一方のブロックに市販３００ｍｍ用アクリル定規をはじき板１４として端部を固定した脱落試験治具１０の切欠き部１２に、図に示すように脱落試験用片１５の化粧料層５の裏面の中心にはじき板１４の先端１４ａが当たるよう化粧料層の面を下側にして端部を固定して取り付けた。次に、はじき板１４の先端１４ａを持ち上げて反らせ、高さ測定目盛１３における１００ｍｍの高さから試験用片１５めがけてはじかせ、化粧料の脱落の有無を観察した。評価は、脱落のない場合を○、脱落した場合を×と評価した。脱落試験結果を表６−１および表６−２に示した。

(Evaluation of Cosmetic Sheet) [Dropping Test] The obtained cosmetic sheet was cut into a 90 mm square with the cosmetic layer as the center to produce a stripping test piece 15. As shown in FIG. 5, two iron blocks having a width of 200 mm, a length of 500 mm, and a height of 80 mm are assembled on an L-shaped fixing base 11, a scale 13 for height measurement is attached to one block, and a commercially available 300 mm acrylic is attached to the other block. As shown in the figure, the tip 14a of the flip plate 14 is formed at the center of the back surface of the cosmetic layer 5 of the drop test piece 15 as shown in the figure. The face of the cosmetic layer was face down so that the end was fixed and attached. Next, the tip 14a of the repellent plate 14 was lifted and warped, and the test piece 15 was repelled from a height of 100 mm on the height measuring scale 13, and the presence or absence of the cosmetics was observed. In the evaluation, a case where there was no dropout was evaluated as ◯, and a case where the dropout occurred was evaluated as ×. The dropout test results are shown in Tables 6-1 and 6-2.

ファンデーションの種類による差は見られなかったが、印刷版の違いが顕著であった。通常のスクリーン印刷版を用いた場合、脱落は全く見られず良好であったが、厚膜スクリーン印刷版を用いた高塗布量の場合、表面粗さ２．７μｍ以下では脱落が生じていた。１．２μｍでは特に著しく製造できないことが明らかであった。

Although there was no difference depending on the type of foundation, the difference between the printing plates was remarkable. When a normal screen printing plate was used, the drop-off was not observed at all, and it was good. However, in the case of a high coating amount using a thick film screen printing plate, the drop-off occurred when the surface roughness was 2.7 μm or less. It was clear that the film could not be manufactured particularly remarkably at 1.2 μm.

  [Test for removal feeling] The center part of the sponge puff was picked and rubbed so as to scrape the center part of the surface of the printed cosmetic layer, and the degree of removal of the cosmetic was evaluated according to the following criteria. The evaluation results are shown in Table 7-1 and Table 7-2.

  (Evaluation criteria) 4 (excellent): It is superior to 3, and the cosmetics are sequentially scraped from the surface even when scraping strongly. 3 (good): Adhesiveness between the base material sheet and the cosmetic layer is good, and the cosmetic layer does not peel off from the sheet surface even when it is strongly scraped off. 2 (Normal): Adhesiveness between the base material sheet and the cosmetic layer is slightly weak, and the cosmetic layer may be peeled off from the surface of the sheet when strongly scraped. 1 (Poor): Adhesiveness between the base material sheet and the cosmetic layer is weak, and the cosmetic layer peels off from the surface of the sheet as a lump even when scraped with a normal force (also referred to as dropping).

ファンデーションの種類による差が見られた。ファンデーション中の油分の多いものほど塗液濃度を高くできることから化粧料層が固くなり、取れ感が向上したものと思われる。印刷版の差も見られ、通常の版を用いた場合、表面粗さ２．７μｍでも取れ感が大幅に向上していることが確認された。厚膜印刷版を用いた場合、２．７μｍ以下では油分の少ないファンデーションの取れ感は満足できない評価となっており、それより粗さが大きくなるとすべてのファンデーションで３以上の評価を示し、ユーザーの使用時においても優れた評価が得られることは明らかである。

Differences were found depending on the type of foundation. It seems that the higher the oil content in the foundation, the higher the concentration of the coating liquid, and the harder the cosmetic layer and the better the feel. Differences in printing plates were also observed, and it was confirmed that when a normal plate was used, the feeling of removal was greatly improved even with a surface roughness of 2.7 μm. When a thick film printing plate is used, the foundation feel with less oil is not satisfactory at 2.7 μm or less, and when the roughness is larger than that, all foundations show an evaluation of 3 or more. It is clear that excellent evaluation can be obtained even in use.

  In addition, as long as it has the above surface roughness, this result shows that there is no difference even if the base sheet is directly on the film surface or a cosmetic receiving layer is provided on the surface of the base sheet. Show.

  Therefore, in the present invention, at least a portion of the base sheet surface on which the cosmetic layer is provided is measured with a stylus type surface roughness measuring instrument defined in JIS B0651, and the method described in JIS B0601. It is preferable to have a surface roughness of 3.5 to 10 μm centerline average roughness expressed according to the above. More preferably, it is 3.5-9.0 micrometers, and 3.5-8.0 micrometers is the most preferable. When the thickness is smaller than 3.5 μm, the anchoring effect of the cosmetic layer is reduced and the adhesiveness is reduced, and not only the cosmetics are likely to fall off when the sample is scraped off, but also the manufacturing process is lost. It becomes difficult and undesirable. If the thickness exceeds 10 μm, the appearance of the cosmetic scraping remaining noticeable at the end of use of the sample is exhibited, which may undesirably impair the user's impression. The surface roughness with a center line average roughness of 3.5 μm is a surface roughness level that is much rougher than that of commercially available mat-coated paper and comparable to rough-skin-finished book paper, which is rough-finished paper.

  As a base material sheet of the present invention, as long as it has the above surface roughness, a film alone or a film in which a cosmetic receiving layer having the above surface roughness is formed on the surface of the film can be used. Instead of the film, a laminate of film and paper may be used. When a large amount of cosmetics is laminated by overprinting as in the present invention, if a base material that allows easy penetration of the solvent, such as coated paper, is used, the oil content in the cosmetics is transferred to the base material along with the penetration of the solvent. It is not preferable because the quality of the material may change. In addition, when a polyolefin-based film such as polyethylene or polypropylene is used, the base material sheet of the printing portion is deformed due to oil. Therefore, what has tolerance with respect to the oil component in cosmetics is preferable.

  A large amount of cosmetic coating solution is applied by overprinting, and hot air of around 105 ° C. is used to dry the cosmetic layer. If the heat resistance of the base sheet is low and the shrinkage at the time of drying is large, peeling occurs at the interface between the cosmetic layer and the base sheet, causing dropping off. Therefore, the base sheet used in the present invention needs to have oil resistance and heat resistance. As a material for the film alone, for example, a polycarbonate film produced by molding with a cooling roll having an embossed surface at the time of film formation, for example, Opulse WPC-E manufactured by Eiwa Co., Ltd. and the like can be mentioned. Polyester film is one of the preferred materials because of its high oil resistance and heat resistance. If the surface roughness can be obtained, it is one of the most preferable ones. A biaxially stretched film is most preferable, but an unstretched or uniaxially stretched polyester film should be used as the base sheet of the present invention as long as it does not peel off at the interface between the cosmetic layer and the base sheet during drying. Can do.

  The cosmetic receiving layer having the above surface roughness is formed on the surface of the film, and the cosmetic receiving layer composed of particles and a binder is formed on the surface of the biaxially stretched film that has been sand-mat processed. Is used. Examples of the particles used for the receiving layer include inorganic mineral particles, glass beads, and plastic particles. The size of the particles is not limited as long as the above surface roughness can be obtained, but a relatively coarse particle size, for example, a combination of particles remaining after 200 mesh and 300 mesh and a binder is one of the preferred combinations. I can say that. Since the fine agglomerated particles of colloidal oil have high oil absorption, it is necessary to combine with a binder having high oil resistance. Examples of the binder include natural water-soluble polymer substances such as sodium alginate and carboxymethyl cellulose. As the synthetic binder, an acrylic resin having high oil resistance is preferably used.

  In the present invention, since the printing using the thick film screen printing plate is repeated twice or more, the peripheral portion of the cosmetic layer becomes smooth, the omission due to the transfer failure at the time of printing can be eliminated, and the coating amount is greatly increased. be able to.

  Moreover, in this invention, since it laminates | stacks on the surface which has the surface roughness of centerline average roughness 3.5-10micrometer, adhesiveness with a cosmetics layer increases, and while being able to prevent dropout in a manufacturing process, it is a free sample. Removal of the cosmetic layer during use is eliminated.

  According to the present invention, the cosmetic layer corresponding to 4 to 5 times is laminated, but there is almost no dropout of the peripheral part due to the dropout or transfer failure of the cosmetic during the manufacturing process, and when the sample is used It has become possible to provide a cosmetic sample that does not cause the cosmetic layer to fall off even if it is strongly scraped off with a puff.

  The best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows a cosmetic sheet (a) in which a cosmetic layer 5 is provided on a part of the surface of a base sheet 1. The composition of the solvent used when adjusting a predetermined concentration of screen printing slurry (coating liquid) by mixing the solvent with a cosmetic such as foundation is the composition of the cosmetic, the screen printing conditions, the target amount of the cosmetic, etc. Is adjusted as appropriate.

  The surface of the base material sheet 1 on which the cosmetic layer 5 is laminated is measured with a stylus type surface roughness measuring instrument stipulated in JIS B0651, and the center line average roughness 3 expressed according to the method described in JIS B0601. It has a surface roughness of 5 to 10 μm and enhances adhesion with the cosmetic layer. As shown in FIG. 3, a cosmetic film receiving layer using a polycarbonate film or a polyester film having a surface roughness of 3.5 to 10 μm, or having a surface roughness on the surface of a polyester film or the like as shown in FIG. It is possible to use a sheet on which is formed. In addition, although not shown in figure, when the adhesive layer and the peeling paper layer are formed in the back surface of the base material sheet 1, it becomes possible to affix a sample to another base material, and is preferable.

  The cosmetic material receiving layer 7 shown in FIG. 4 is formed by printing or coating a layer composed of particles and a binder on the surface of a biaxially stretched polyester film that has been sand-matted. As shown in FIG. 4, it may be printed and partially provided in accordance with the position where the cosmetic layer of the base sheet is laminated, or may be applied and provided on the entire surface of the base sheet. When providing partially, it considers the alignment of printing of a cosmetics layer, and it is provided with a dimension 2-4 mm larger than the cosmetics layer as a whole.

  Examples of the particles used in the receiving layer include inorganic mineral particles or glass beads, plastic particles, and the size of the particles is not particularly limited, but paper coating or internal fillers, pigments, etc. The average particle size of 1 μm to 105 μm can be used. For example, particles having a mesh size of 325 mesh remaining after passing through 200 mesh corresponding to about 44 to 74 μm are preferably used. Examples of the binder include natural water-soluble polymer substances such as sodium alginate and carboxymethyl cellulose. As the synthetic binder, an acrylic resin having high oil resistance is preferably used.

The cosmetic layer 5 is formed by screen printing using a slurry (coating solution) of which the concentration is appropriately adjusted using isopropyl alcohol as a solvent for the cosmetic for foundation using the base sheet having the surface roughness. The shape and size of the cosmetic layer 5 are appropriately determined. For example, if it is a 34 mm × 49 mm rectangle as a single cosmetic layer in the amount of 5 doses, a thick film screen printing plate that forms a plurality of cosmetic layers with a target of 300 mg (180 g / m ² ) of adhesion is obtained. After being used for 3 times overprinting, it is dried with hot air controlled at 105 ° C. or lower to produce the cosmetic sheet (a) shown in FIG.

Separately, an easy peel laminated film in which a polyester film and an easy peel film are laminated with an adhesive is prepared as the covering film 4. Other than the transparent part provided so that the surface of the inner foundation can be seen through the film when it is distributed as a sample on the back of the polyester film of this laminated film, that is, the side laminated with the easy peel film and the adhesive. Beautifully printed. The easy peel film can be used as it is to provide an easy peel open function for lids such as food containers, and it is composed of 2 to 3 layers and is commercially available from several companies. In the case of PET-based easy peel film ABF64C manufactured by Tosero Co., Ltd., this easy peel film has a configuration of HSPET (heat seal PET) / AD (adhesive layer) / PE (treated surface). . The PE surface is laminated with the printed surface of the polyester film and an adhesive to constitute the covering film layer 4.

The printing machine used was a semi-automatic screen printing machine (manufactured by Sakurai Graphic Systems Co., Ltd., Melody MARK2) equipped with a stainless steel 40 mesh thick film screen printing plate (resin film thickness 300 μm). In the printing plate, a plurality of 34 mm × 49 mm rectangular cosmetic layers are formed as one cosmetic layer, and the average roughness of the center line is set at a target of 180 g / m ² of the cosmetic layer. The above-mentioned base material sheet on which a 5 μm cosmetic receiving layer is formed is overprinted three times and dried with hot air controlled at 105 ° C. or lower to form a cosmetic layer on the cosmetic receiving layer of the base material sheet. A cosmetic sheet was prepared.

  Separately, an easy peel laminated film in which a 38 μm polyester film and a 30 μm commercially available easy peel film (ABF64C) were laminated as a coating film layer was prepared. Except for the transparent part provided on the back side of the polyester film of this laminated film, that is, the side laminated with the easy peel film and adhesive so that the surface of the internal foundation can be seen through the film when it is distributed as a sample. It was beautifully printed.

Furthermore, an opening where the cosmetic layer is exposed is opened, and a 12 μm polyester film is formed on the surface of the coating layer of a commercially available single-side coated paper having a basis weight of 260 g / m ² as a protective sheet laminated on the surface of the base sheet. Prepare a laminate with an adhesive layer and a release paper layer on the back, and punch the 38 mm x 53 mm rectangular opening corresponding to the exposed position of the cosmetic layer of the cosmetic sheet. A sheet was produced.

  A heat sheet PET surface of the prepared covering film layer on the easy peel film side and a polyester film surface of the protective sheet are fixed by heat sealing to produce a laminated sheet shown in FIG. 2, the release paper layer is peeled off, and the makeup shown in FIG. The cosmetic layer was stacked and pressed onto the material sheet so as to be exposed and fixed, and cut into a predetermined size to produce the cosmetic sample of the present invention shown in FIG. In this sample, 300 mg of the foundation for 5 trials was adhered, and the cosmetic layer having a mesh pattern with a smooth peripheral edge and a clear surface could be seen through the covering film of the opening. .
