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 binder components, the hardness of the binder components shown in Table 1 was measured by the method described above.

[0254] In addition, 5 phr of photopolymerization initiator "Ilgacyua-184" was added to the binder component, and hollow silica was added so that the total amount of photopolymerization initiator and binder: hollow silica = 62.5: 37.5 (weight %), to obtain the low refractive index layer film-forming composition, use this composition, detect abrasion resistance and chemical corrosion resistance by the above method, the results are shown in Table 1.

experiment example 2

[0264] In order to evaluate the pretreatment of the hollow silica, the pretreatment shown in Table 2 was performed on the hollow silica by the following method. In addition, as a silane coupling agent, an acrylic-modified silane compound "KBM-5103" (CH 2 =CH-COO-(CH 2 ) 3 -Si-(OCH 3 ) 3 ).

[0265] Pretreatment method (1): with 3.8% by weight of hollow silica, 96% by weight of alcohol solvent (a mixed solvent of isopropanol and isobutanol 19:81 (weight ratio)), 3% by weight of acetic acid, 1% by weight of The reaction solution made of water and 0.04% by weight of silane coupling agent was put into a pressure-resistant stainless steel container with PTFE (polytetrafluoroethylene) inside, and hydrothermally synthesized at the temperature shown in Table 2 for 4 hours.

[0266] Pretreatment method (2): put the reaction solution prepared in the same way as the above-mentioned pretreatment method (1) into a microwave generator manufactured by Tokyo Electronics Co., Ltd., and ir...

experiment example 3

[0281] In order to study the antifouling effect of the fluorinated silane coupling agent, the fluorinated silane coupling agent "KBM-7803" (C 8 f 17 -(CH 2 ) 2 -Si-(OCH 3 ) 3 ) As a silane coupling agent, the same as the pretreatment method (1) of Experimental Example 2, the pretreatment of hollow silica was performed at a reaction temperature of 120° C. by a hydrothermal method.

[0282] In addition, only the fluorinated silane coupling agent was added in the same manner as the pretreatment method (3) of Experimental Example 2 to prepare unreacted hollow silica.

[0283]Using hollow silica without pretreatment and hollow silica after pretreatment, dipentaerythritol hexaacrylate, which was evaluated as the best wear resistance in Experimental Example 1, was used as a binder component. 5 phr of the polymerization initiator "Irugacyua-184" was added to the ingredients so that the total amount of the photopolymerization initiator and binder: hollow silica = 62.5:37.5 (weight...

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.
