Problems solved by technology

[0083] Therefore, it can be considered that such a coating type anti-reflection film is also suitable for solar cell modules. In the existing anti-reflection film, the anti-reflection performance is not sufficient, and especially the ultraviolet rays with high solar energy are shielded. Therefore, using such an anti-reflection film Reflective film, sometimes it will lead to lower power generation efficiency

experiment example 1

[0253] In order to evaluate the binding agent components, the hardness of the binding agent components shown in Table 1 was measured by the above-mentioned method.

[0254] In addition, 5 phr of the photopolymerization initiator "Irucou Yua-184" was added to the binder component, hollow silica was added, and the total amount of photopolymerization initiator and binder: hollow silica = 62.5:37.5 (weight %) to obtain a composition for forming a low refractive index layer. Using this composition, the abrasion resistance and chemical corrosion resistance were tested by the above method. The results are shown in Table 1.

experiment example 2

[0263] In order to evaluate the pretreatment of the hollow silica, the hollow silica was subjected to the pretreatment shown in Table 2 by the following method. In addition, as the silane coupling agent, an acrylic-modified silane compound "KBM-5103" (CH 2 =CH-COO-(CH 2 ) 3 -Si-(OCH 3 ) 3 ).

[0264] Pretreatment method (1): 3.8% by weight hollow silica, 96% by weight alcohol solvent (mixed solvent of isopropanol and isobutanol 19:81 (weight ratio)), 3% by weight acetic acid, 1% by weight The reaction liquid made of water and 0.04% by weight of the silane coupling agent was put into a pressure-resistant stainless steel container with PTFE (polytetrafluoroethylene) attached inside, and hydrothermally synthesized at the temperature shown in Table 2 for 4 hours.

[0265] Pretreatment method (2): Put the reaction solution prepared in the same manner as the above pretreatment method (1) into a microwave generator manufactured by Tokyo Electronics, and irradiate it at the set temperatur...

experiment example 3

[0279] In order to study the antifouling effect of fluorinated silane coupling agent, fluorinated silane coupling agent "KBM-7803" manufactured by Shin-Etsu Chemical Co., Ltd. (C 8 F 17 -(CH 2 ) 2 -Si-(OCH 3 ) 3 ) As the silane coupling agent, as in the pretreatment method (1) of Experimental Example 2, the hollow silica pretreatment was performed by a hydrothermal method at a reaction temperature of 120°C.

[0280] In addition, as in the pretreatment method (3) of Experimental Example 2, only the fluorinated silane coupling agent was added to prepare unreacted hollow silica.

[0281] Use unpretreated hollow silica, pretreated hollow silica, and use dipentaerythritol hexaacrylate, which is evaluated as the best abrasion resistance in Experimental Example 1, as the binder component. Add 5 phr of the polymerization initiator "Iruco Yua-184" to the ingredients to make the total amount of the photopolymerization initiator and the binder: hollow silica = 62.5: 37.5 (weight ratio) to pr...

Abstract

An antireflection film comprising transparent base film 1 and, sequentially superimposed thereon, hard coat layer (2), high refractive index layer 3 and low refractive index layer 4. Alternatively, there is provided an antireflection film comprising a transparent base film and, sequentially superimposed thereon, a conductive high refractive index hard coat layer and a low refractive index layer. The low refractive index layer is obtained through irradiating of a coating film comprising hollow silica microparticles, a polyfunctional (meth)acrylic compound and a photopolymerization initiator with ultraviolet rays in an atmosphere of 0 to 10,000 ppm oxygen concentration so as to harden the same.
