Hereinafter, the present invention will be described in detail with reference to the drawings showing a protector according to Embodiment 2. FIG. 12 is a schematic cross-sectional view showing a protector.
As shown in FIG. 12, the protector includes a permeable sheet 1, and a rough surface portion 5 having a rough surface 5 a having many irregularities is provided on the entire back surface of the sheet 1. The ratio of the main components constituting the rough surface portion 5 is 25 to 30 weight percent isobutyl alcohol, 20 to 25 weight percent methyl isobutyl ketone, 0.1 to 1 weight percent toluene, and 30 to 40 weight percent polyfunctional acrylate. . An appropriate amount of auxiliary agent is also included. The rough surface 5 a is formed of polyfunctional acrylate, and the rough surface 5 a is located on the opposite side of the sheet 1. The unevenness depth or protrusion width of the rough surface 5a is longer than the wavelength of light, for example, 1 micron.

  Even when the sheet 1 is arranged on the flat displays 11 and 21 and the user presses the sheet 1 for operation, the rough surface 5a causes the wavelength of light between the flat displays 11 and 21 and the sheet 1 to be reduced. In addition, a sufficiently large gap can be secured and the occurrence of Newton rings can be prevented. The rough surface portion 5 only needs to be formed with a rough surface 5a, and the rough surface 5a is not limited to the case where it is formed of a polyfunctional acrylate. For example, a rough surface portion 5 containing a large number of fine particles is provided on the back surface of the sheet 1 to form a rough surface 5a with the fine particles, and a gap sufficiently larger than the wavelength of light is formed between the flat displays 11 and 21 and the sheet 1. It may be secured.

  The thickness of the rough surface portion 5 is 3 to 5 microns. A decorative portion 2 is provided on the rough surface portion 5, and an adhesive portion 3 is provided on the decorative portion 2. A film 4 is provided on the back surface of the sheet 1, and the film 4 is in contact with the adhesive portion 3. The film 4 can be peeled off from the bonding part 3.

Next, the manufacturing process of a protector is demonstrated. FIG. 13 is a process diagram showing the production process of the protector.
As shown in FIG. 13A, first, a sheet material 100 is installed. Next, as shown in FIG. 13B, the liquid rough surface portion 5 is applied to the entire back surface of the original sheet 100 and cured. The hardened rough surface portion 5 has a layer shape. And as shown to FIG. 13C, the decoration part 2 is printed on the rough surface part 5 in the grid | lattice form in the position corresponding to the frame part around the flat displays 11 and 21. FIG. Then, as shown in FIG. 13D, a plurality of adhesion portions 3 are staggered by silk screen printing on the decorative portion 2 using an adhesive, and a dot pattern is formed by the plurality of adhesion portions 3. The adhesion part 3 printed on the decoration part 2 is fixed to the decoration part 2.

  And as shown to FIG. 13E, the film 4 is provided in the back surface of the original sheet 100 of sheets. Next, as shown in FIG. 13F, the raw sheet 100 is punched out and has dimensions corresponding to the vertical and horizontal dimensions of the tablet-type terminal 10 or the smartphone 20. A plurality of protective bodies provided with 3 are manufactured. When punching out the original sheet 100, notches 1a and 1b are also formed. The original sheet 100 may be divided after the notches 1a and 1b are formed, and the notches 1a and 1b may be formed after the original sheet 100 is divided.

  The decorative portion 2 may be printed on the front surface of the original sheet 100 at a position corresponding to the frame portion around the flat displays 11 and 21, or the decorative portion 2 may be printed on the front surface of the sheet 1. The process of printing the decorative portion 2 on the front surface of the original sheet 100 or the sheet 1 may be performed in an order suitable for manufacturing the protector in the series of processes described above. For example, it may be executed at the beginning of a series of steps or may be executed at the end. In this case, a dot pattern is printed on the rough surface portion 5. Alternatively, after the decorative portion 2 is printed on the back surface of the original sheet 100, the rough surface portion 5 may be applied and a dot pattern may be printed on the rough surface portion 5.

  In the protector according to Embodiment 2, even if an external force acts on the front surface of the sheet 1 and the gap between the back surface of the sheet 1 and the flat displays 11 and 21 is narrowed, the rough surface portion 5 A gap sufficiently larger than the wavelength of light is secured between the flat display and a Newton ring does not occur. Therefore, it is possible to avoid the visibility of the flat displays 11 and 21 being hindered by Newton rings. Further, by associating the vertical and horizontal dimensions of the sheet 1 with the flat displays 11 and 21, no Newton ring is generated even if the user touches any part of the flat displays 11 and 21. The user can surely view the video displayed on the flat display, and even if the GUI displayed on the flat displays 11 and 21 is pressed, the visibility is not deteriorated due to Newton's ring.

  In addition, the structure same as Embodiment 1 among the structures of the protector which concerns on Embodiment 2 attaches | subjects the same code | symbol, and abbreviate | omits the detailed description.

(Embodiment 3)
Hereinafter, the present invention will be described in detail with reference to the drawings showing a protector according to Embodiment 3. FIG. 14 is a process diagram showing the production process of the protector.

  As shown in FIG. 14G, the protector is provided on the entire front surface of the sheet 1 and includes a transparent contamination prevention layer 6 that prevents contamination by oil and moisture. The contamination prevention layer 6 is made of one or both of a thermosetting resin and an ionizing radiation curable resin. In particular, since the coating hardness after curing is excellent, the contamination prevention layer 6 preferably contains at least an ionizing radiation curable resin. The ionizing radiation curable resin is used alone or in combination with a photopolymerizable monomer or a photopolymerizable prepolymer. The ionizing radiation curable resin may contain a compound or the like (ionizing radiation (light) polymerization initiator) that generates active radical species upon irradiation with ionizing radiation (light).

  At least an isocyanuric acid derivative is used as a photopolymerizable monomer (an example of a reactive monomer) contained in the ionizing radiation curable resin. The isocyanuric acid derivative has an isocyanuric acid skeleton, and has a structure in which a polymerizable reactive group and an alkylene oxide chain are bonded to the isocyanuric acid skeleton.

  The contamination prevention layer 6 contains an ionizing radiation curable resin, and an isocyanuric acid derivative is used as a photopolymerizable monomer as an example of a reactive monomer. Instead of or together with the ionizing radiation curable resin, a thermosetting resin may be contained. When the anti-staining layer 6 contains a thermosetting resin, a thermopolymerizable monomer or prepolymer is used alone or in combination. If necessary, a thermal polymerization initiator, that is, a compound that generates active radical species by heating, or the like is contained. In this case, an isocyanuric acid derivative may be used as the thermally polymerizable monomer.

  When fingerprints adhere to the contamination prevention layer 6, in order to make the attached fingerprints less noticeable, appropriate hydrophilicity and lipophilicity may be imparted to the surface, rather than imparting strong water repellency and oil repellency. It is valid. By using a specific isocyanuric acid derivative, moderate hydrophilicity and lipophilicity can be expressed on the surface of the cured film. By containing a specific isocyanuric acid derivative in the photopolymerizable monomer, it is possible to develop moderate hydrophilicity and lipophilicity in the cured film. Since the degree of contact of the fingerprint component (aqueous component and oil component) with the surface does not become too small, the fingerprint component spreads moderately on the surface. As a result, even when a fingerprint adheres to the surface after curing, the attached fingerprint becomes difficult to stand out. Moreover, the hardness fall of the contamination prevention layer 6 after hardening can also be prevented. Each performance of making the fingerprint inconspicuous and preventing the decrease in hardness is balanced.

  The kind of the polymerizable reactive group bonded to the isocyanuric acid skeleton of the isocyanuric acid derivative is not particularly limited. For example, an acryloyl group, a methacryloyl group, a vinyl group, an epoxy group, etc. are mentioned. Among these, an acryloyl group and a methacryloyl group are particularly preferable.

  The number of polymerizable reactive groups bonded to the isocyanuric acid skeleton of the isocyanuric acid derivative is not particularly limited, but is preferably 2 or more. By having at least two polymerizable reactive groups bonded to the nitrogen atom of the isocyanuric acid skeleton, the crosslinking density is increased. When an isocyanuric acid derivative is contained, the hardness may decrease. By increasing the crosslinking density, it is possible to prevent a decrease in hardness.

  An alkylene oxide is bonded to the isocyanuric acid skeleton of the isocyanuric acid derivative. Thereby, moderate hydrophilicity can be expressed in the film after hardening, and it becomes easy to wipe off a fingerprint. In particular, ethylene oxide (EO) is preferable. By containing EO, it becomes easier to express moderate hydrophilicity in the contamination prevention layer 6 as compared with the case of containing propylene oxide (PO), butylene oxide (BO), or the like.

A unit derived from a closed ring structure (cyclo ring) may be bonded to the isocyanuric acid skeleton of the isocyanuric acid derivative. The ring structure is, for example, lactone, lactam, cycloolefin (eg, cyclopentene, cyclohexene, etc.), tetrahydrofuran, dioxane, silacyclopentene, cyclodecane, isobornyl. The unit derived from lactone is, for example, (—CO—O— (CH ₂ ) _n ), and the unit derived from lactam is, for example, (—NH—O— (CH ₂ ) _n ).

  The lactone is not particularly limited, but caprolactone is preferable. Caprolactone is not particularly limited. For example, ε-caprolactone, δ-caprolactone, and γ-caprolactone. ε-Caprolactone is preferred. Lactones other than caprolactone may be used. For example, δ-valerolactone, γ-butyrolactone, γ-valerolactone, β-propiolactone and the like. By having a unit derived from lactone, lactam or the like in the molecule, it is possible to cause the antifouling layer 6 to exhibit appropriate lipophilicity, making it difficult to visually recognize the fingerprint.

  The molecular weight of the isocyanuric acid derivative is preferably 200 or more and 5000 or less. When the value of the molecular weight is too large, the hardness of the contamination prevention layer 6 may be lowered. When the molecular weight value is too small, it becomes difficult for the contamination prevention layer 6 to exhibit appropriate hydrophilicity and lipophilicity. In addition, the value of molecular weight is calculated | required as a weight average molecular weight of polystyrene conversion using mobile phase solvents, such as tetrahydrofuran.

  The HLB (Hydrophile-Lipophile-Balance) value of the isocyanuric acid derivative by the Griffin method is preferably 10 or more and 18 or less, more preferably more than 12 and 15 or less. The HLB value is calculated by the following formula.

  [Expression 1] HLB value = 20 × total formula weight of hydrophilic part / molecular weight HLB value is an important index indicating the characteristics of the isocyanuric acid derivative, and is a value indicating the degree of hydrophilicity or lipophilicity. . Generally, the HLB value takes a value from 0 to 20, and the closer to 0, the higher the lipophilicity, and the closer to 20, the higher the hydrophilicity.

  Since an isocyanuric acid derivative whose HLB value is controlled within a predetermined range is used, the hydrophilicity of the cured film is appropriately improved. As a result, the surface characteristics of the contamination prevention layer 6 can be easily controlled within a range described later. Since fingerprints contain sweat, moisture adhesion and wettability are also important factors that affect fingerprint resistance. In order to express the effect of making the stains due to fingerprints inconspicuous by spreading the fingerprints on the surface of the contamination prevention layer 6, it is desirable that the surface of the film after curing has an appropriate hydrophilic property.

  When the HLB value of the isocyanuric acid derivative is too small, there is a possibility that moderate hydrophilicity is not expressed in the cured film. When the HLB value is too large, the hydrophilicity becomes too strong and the fingerprint wiping property is lowered.

  Next, the manufacturing process of a protector is demonstrated. As shown in FIG. 14A, first, the sheet material 100 is installed. Next, as shown in FIG. 14B, a liquid antifouling material is applied to the entire front surface of the original sheet 100 and cured. The cured antifouling material becomes the antifouling layer 6. Thereafter, similarly to the first or second embodiment, the rough surface portion 5, the decorative portion 2, the adhesive portion 3, and the film 4 are sequentially provided on the back surface of the original sheet 100. And the sheet | seat original fabric 100 is punched out, and the several protection body which provided the some adhesion part 3 in the peripheral part of the one surface of the sheet | seat 1 is manufactured (FIG. 14C-FIG. 14G).

  Since the contamination prevention layer 6 is formed on the front surface of the sheet 1, it is possible to prevent adhesion of oil or the like to the front surface of the sheet 1. Even when the user touches the front of the sheet 1 with a finger, fingerprints due to oil, moisture, etc. are unlikely to occur. Even if the user touches the sheet 1 for touch panel operation, the visibility of the flat displays 11 and 21 can be maintained. Moreover, the designability and cleanliness can be maintained.

  Considering the permeability of the protector, the Newton ring prevention function and the strength, the pencil hardness of the surface of the sheet 1 is H to 6H (JIS standard 7105), and the transmittance of the protector is 80 to 95% (JIS standard 7105). The haze (cloudiness) is preferably set to 1.6 to 8.5% (JIS standard K5600). For example, the pencil hardness is set to 3H, the transmittance is set to 91%, and the haze is set to 6.5%. Thereby, each function of permeability, a Newton ring prevention function, and intensity is not impaired, it is exhibited in good balance, and maintenance and improvement of visibility can be aimed at.

  The contamination prevention layer 6 may be made of a fluorine resin. For example, PTFE (polytetrafluoroethylene), PFA (tetrafluoroethylene / perfluoroalkyl vinyl ether copolymer), FEP (tetrafluoroethylene / hexafluoropropylene copolymer), ETFE (tetrafluoroethylene / ethylene copolymer), You may comprise with fluororesins, such as PVDF (polyvinylidene fluoride), PCTFE (polychlorotrifluoroethylene), and ECTFE (chlorotrifluoroethylene-ethylene copolymer).

  Next, a modification of the third embodiment will be described. In the contamination prevention layer 6 according to the modified example, a metal such as silver and an inorganic antibacterial agent supported on zeolite, silica gel, apatite and the like are mixed. In addition, a photocatalyst (deodorant active substance) containing metal oxide such as zinc oxide, tungsten trioxide, cerium oxide and titanium oxide or phthaloanine is mixed. Antibacterial and deodorizing can be realized by an inorganic antibacterial agent and a photocatalyst. The photocatalyst is preferably titanium oxide from the viewpoint of structural stability and photocatalytic activity.

  Since the pollution prevention layer 6 contains an inorganic antibacterial agent or a photocatalyst, it is excellent in antibacterial properties and deodorizing properties, and the protective body can be kept clean. Therefore, the user's hygiene can be improved.

  Note that, in the configuration of the protector according to the third embodiment, the same reference numerals are given to the same configurations as those in the first or second embodiment, and detailed description thereof is omitted.

  As shown in FIG. 15G, the protector is provided on the entire front surface of the sheet 1 and includes a transparent self-healing layer 7 that repairs scratches. The self-healing layer 7 is made of a crosslinked polyurethane resin having a high elastic coefficient. For example, it consists of a diuret or polyisocyanate burette type urethane in aliphatic or cycloaliphatic, and a cross-linked polyurethane resin such as polyurethane obtained from isocyanate. When an object scratches the self-healing layer 7, it is visually recognized as a scratch on the surface. A portion that is visually recognized as being scratched is depressed by elasticity, but is not destroyed. The recessed portion recovers with time due to the elastic restoring force, and the scratch disappears.

  Next, the manufacturing process of a protector is demonstrated. As shown in FIG. 15A, first, the original sheet 100 is installed. Next, as shown in FIG. 15B, a liquid cross-linked polyurethane resin material is applied to the entire front surface of the original sheet 100 and cured. The cured resin material becomes the self-healing layer 7. Thereafter, similarly to the first or second embodiment, the rough surface portion 5, the decorative portion 2, the adhesive portion 3, and the film 4 are sequentially provided on the back surface of the original sheet 100. And the sheet | seat original fabric 100 is punched out, and the several protection body which provided the some adhesion part 3 in the peripheral part of the one surface of the sheet | seat 1 is manufactured (FIG. 15C-FIG. 15G).

  Since the self-healing layer 7 made of a cross-linked polyurethane resin having a high elastic coefficient is formed on the front surface of the sheet 1, even when an object scratches the front surface of the sheet 1 and a scratch is generated, the scratch disappears with time. Therefore, it is possible to prevent the visibility of the flat displays 11 and 21 from being hindered by scratches.

  The self-healing layer 7 may include an inorganic antibacterial agent or a photocatalyst. In this case, the self-repairing layer 7 is excellent in antibacterial properties and deodorizing properties, and the protective body can be kept clean.

The phosphorescent material is, for example, a combination of a phosphorescent pigment and an activation material. The phosphorescent pigment is, for example, zinc sulfide or strontium aluminate. The activator is, for example, a metal ion such as divalent europium ion (Eu ²⁺ ), trivalent dysprosium ion (Dy ³⁺ ), or neodymium ion (Nd ³⁺ ). The combination of the phosphorescent pigment and the activator is excited by light in the wavelength region of about 200 to 450 nm and emits fluorescence in the wavelength region of about 450 to 600 nm (purple blue to light yellowish green).

  Next, the manufacturing process of a protector is demonstrated. As shown in FIG. 16A, first, the sheet material 100 is installed. Next, as shown in FIG. 16B, the liquid rough surface portion 5 is applied to the entire back surface of the original sheet 100 and cured. The hardened rough surface portion 5 has a layer shape. Then, as shown in FIG. 16C, a liquid resin mixed with a phosphorescent material is applied to the rough surface portion 5 at a position corresponding to the frame portion around the flat displays 11 and 21 and cured.
