Description

Technical Field

[0001] The present disclosure relates to a polymerizable composition.

Background Art

[0002] A film having a fine concavo-convex structure with a surface of a visible light wavelength or less is known to be used as an antireflection film. On the surface of such a concavo-convex structure, since the refractive index continuously changes from the air layer with respect to incident light, the reflected light can be dramatically reduced. Patent Documents 1 to 3 disclose films having such a fine concavo-convex structure on the surface.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The film as described above has excellent antireflection properties due to the concavo-convex structure on its surface. On the other hand, in the film as described above, when dirt such as fingerprints (sebum) adheres to the surface, the dirt easily spreads along the concavo-convex structure, and it is difficult to wipe off the dirt because the dirt enters the concave portions. Furthermore, when wiping off the dirt adhering to the surface, there is also a problem that the concavo-convex structure collapses and the antireflection property is impaired. Since the difference from the reflectance of the normal portion becomes large at the portion where such dirt adheres or the portion where the concavo-convex structure collapses, the portion can be easily visually recognized even by the naked eye.

[0005] Accordingly, an object of the present disclosure is to provide a polymerizable composition capable of providing a film excellent in antifouling properties (e.g., fingerprint wiping property) and mechanical strength (e.g., scratch resistance). [Means for Solving the Problems]

[0303] (Step 2) In Step 2, as shown in FIG. 4, the polymerizable composition layer 5 is pressed against a mold 6 to form a concavo-convex structure on the surface of the polymerizable composition layer. At this time, the polymerizable composition layer is sandwiched between the mold and the support. As a result, the concavo-convex structure on the surface of the mold is transferred to the surface of the polymerizable composition layer (the surface opposite to the support side).

[0304] (Step 3) In Step 3, the polymerizable composition layer 5 having the concavo-convex structure on the surface is cured to form a polymer layer 3. As a result, a polymer layer having a concavo-convex structure on the surface is formed.

Further, the number of times of irradiation with active energy rays on the polymerizable composition may be only once or may be a plurality of times. This Step 3 may be performed at the same timing as Step 2.

[0306] The active energy rays are not particularly limited, and examples thereof include electromagnetic waves in a wavelength region of 350 nm or less, that is, ultraviolet light, electron beams, X-rays, γ-rays, and the like.

[0307] (Step 4) In Step 4, as shown in FIG. 5, the mold 6 is peeled off from the polymer layer 3. As a result, the laminate of the present disclosure is obtained.

[0308] (Alternative method) As an alternative method to Steps 1 and 2 above, after applying the polymerizable composition of the present disclosure to the surface of a mold to form a polymerizable composition layer, the support may be pressed against the polymerizable composition layer on the mold in a state where the polymerizable composition layer is sandwiched between the mold and the support to form a concavo-convex structure on the surface of the polymerizable composition layer.

[0309] (Mold) The above mold has an uneven structure corresponding to the uneven structure of the polymer layer on its surface.

[0310] The shape of the above mold is not particularly limited, and examples include a flat plate shape, a roll shape, etc.

[0311] In one aspect, the shape of the mold is a roll shape with an uneven structure on its outer peripheral surface. By using such a mold, the above steps 1 to 4 can be carried out continuously and efficiently, and productivity can be improved.

[0312] The material of the above mold is not particularly limited, and examples include glass; metals such as stainless steel and nickel; polyolefin resins such as polypropylene, polymethylpentene, and cyclic olefin-based polymers (typically, norbornene-based resins, for example, "Zeonor (registered trademark)" manufactured by Zeon Corporation, "Arton (registered trademark)" manufactured by JSR Corporation); polycarbonate resins; resins such as polyethylene terephthalate, polyethylene naphthalate, and triacetyl cellulose.

[0313] The method for manufacturing the uneven structure of the above mold is not particularly limited, and examples include an anodization method, a photolithography method, a laser drawing method, an electron beam drawing method, a plasma etching method, a mechanical cutting method, etc.

[0314] It is preferable that the surface of the above mold is subjected to a release treatment. By subjecting the surface of the mold to a release treatment, the mold can be easily peeled off from the polymer layer. In addition, since the surface free energy of the mold becomes low, in the above step 2, when the support is pressed against the mold, the compound (B) can be uniformly oriented on the surface of the polymerizable composition layer in contact with the mold, and the antifouling property is improved.

[0315] Examples of the mold release agent used for the mold release treatment of the above mold include, for example, fluorine-based compounds, silicon-based compounds, phosphate ester-based compounds, etc. In particular, fluorine-based compounds are preferred, and examples include Optool (registered trademark) DSX (Daikin Industries, Ltd.).

[0316] Hereinafter, the article of the present disclosure will be described in Examples, but the present disclosure is not limited to the following Examples.

[0317] Synthesis Example 57 g of SUMIDUR N3300 (cyclic trimer of hexamethylene diisocyanate, manufactured by Sumitomo Bayer Urethane Co., Ltd., NCO group content 21.9%) was dissolved in 1000 g of Zeorola H (manufactured by Nippon Zeon Co., Ltd.), 0.1 g of dibutyltin dilaurate was added, and at room temperature, while stirring, 244 g of a solution of CF3CF2O-(CF2CF2CF2O) n -CF2CF2CH2OH (n = 11) dissolved in 300 g of Zeorola H was added dropwise, and the mixture was stirred overnight at room temperature. The solution was heated to 40 - 45 °C, 24.4 g of hydroxyethyl acrylate was added dropwise and stirred. The end point of the reaction was determined by IR when the absorption of NCO completely disappeared, and a composition A containing a fluoropolyether group-containing compound with a solid content of 20% by mass was obtained. Example As the components contained in the polymerizable composition of the present disclosure, the compounds shown in Table 1 below were prepared.

[0318]

Table 1

[0319] As a support, Fujitac TD-60 (60 μm thick, Fujifilm Corporation) (hereinafter also referred to as "TAC") was prepared.

[0320] As a mold, an intaglio plate made of Ni (Kyodo International Co., Ltd.) with conical recesses having a pitch of 250 nm and a depth of 350 nm being patterned was prepared. Such a mold was immersed in a solution in which Optool DSX (Daikin Industries, Ltd.) was diluted 200-fold with S-135 (Fluorotechnology Co., Ltd.) for 3 minutes. Next, the lifted mold was annealed at 100 °C for 1 hour. Then, the surface of the mold was rinsed with S-135 to remove unreacted Optool DSX.

[0321] ·Manufacture of laminate Predetermined components were uniformly dissolved in a light-shielding container in the formulation shown in Table 2 below to obtain a polymerizable composition. The obtained polymerizable composition was applied onto the surface of a support with a bar coater such that the thickness of the polymerizable composition became 7 μm. Next, with the polymerizable composition layer sandwiched between the mold and the support, the support was pressed against the mold, and ultraviolet rays (integrated irradiation dose: 1,200 mJ / cm 2 ) were irradiated from the support side using a UV lamp "LIGHT HANMAR6J6P3" manufactured by Heraeus to cure the polymerizable composition layer and form a polymer layer. The mold was peeled off from the polymer layer to obtain a film which is the laminate of the present disclosure.

[0322] ·Evaluation Regarding the obtained film, as shown below, the substrate adhesion, scratch resistance, fingerprint wiping property, and visual reflectance were measured. The results are shown in Table 2.

[0323] <Substrate adhesion> First, with respect to the surface of the film, using a cutter knife, vertical 11 cuts and horizontal 11 cuts were made in a grid pattern at 1 mm intervals to engrave 100 square meshes (1 mm square). Next, a polyester adhesive tape "No. 31B" manufactured by Nitto Denko Corporation was pressure-bonded to the mesh portion, and then the adhesive tape was peeled off from the surface of the mesh portion in a direction of 90° at a speed of 100 mm / s. Thereafter, the peeling state of the polymer layer on the substrate was visually observed. The criteria for determination are as follows. 〇: No peeling occurred at all meshes. ×: Peeling occurred at one or more meshes.

[0324] <Scratch resistance> Using a "rubbing tester" (manufactured by Imoto Seisakusho Co., Ltd.) as the testing machine, the film was fixed horizontally on the stage. Using the Tracie standard "Color Cloth (Navy)" (Toray Industries, Inc.) as the friction element, with a load of 1 kg / cm 2 , a stroke width of 30 mm, a speed of 80 rpm, and 30,000 reciprocations of rubbing, the surface of the film was rubbed. Then, the rubbing state of the film surface was visually observed. The judgment criteria were as follows. ○: There was no change compared to before rubbing. △: It appeared slightly whitened. ×: It appeared clearly whitened.

[0325] <Fingerprint wiping property> First, a black PET plate was attached to the surface of the film opposite to the polymer layer of the support via an optical adhesive layer. Then, fingerprints were attached to the surface of the polymer layer of the film (the surface opposite to the side where the black PET plate was attached), and after rubbing 10 times with "BEMCOT M-3II" (Asahi Kasei Corporation), it was visually observed whether the fingerprints could be wiped off. The judgment criteria were as follows. ○: The fingerprints were completely wiped off and no residue was visible. △: The fingerprints were not prominent, but when light from a fluorescent lamp was shone on it, a slight residue was visible. ×: The fingerprints could not be wiped off at all.

[0326] <Visual reflectance> First, a black PET plate was attached to the surface of the film opposite to the polymer layer of the support via an optical adhesive layer. Then, for the surface of the polymer layer of the film (the surface opposite to the side where the black PET plate was attached), the visual reflectance under a D65 light source was measured using a spectrophotometer "CM-26d" (Konica Minolta Inc.). The lower the visual reflectance, the better the anti-reflection property. Also, the visual reflectance was measured in the same way for the evaluation sites of the above-mentioned scratch resistance and fingerprint wiping property. It is preferable that there is no change in the visual reflectance after scratching and after wiping the fingerprints.

[0327]

Table 2

[0328] From the above results, it was confirmed that Examples 1 to 11 in which the polymer layer was formed using the polymerizable composition of the present invention had excellent substrate adhesion, scratch resistance, fingerprint wiping property, and visual reflectance.

Industrial Applicability
