Embodiment approach 1
[0087] figure 1 It is a cross-sectional schematic diagram of the laminated body of Embodiment 1. like figure 1 As shown, the laminated body 10 of Embodiment 1 has the antireflection film 12 and the protective film 13 stuck on the above-mentioned antireflection film 12 . The laminate according to Embodiment 1 is attached to the base material 11 , so that reflection occurring on the surface of the base material 11 can be reduced.
[0088] In Embodiment 1, a moth-eye film is used for the anti-reflection film 12, and most of the light incident on the surface of the moth-eye film 12 is transmitted through the interface between the air and the moth-eye film 12 and the interface between the moth-eye film 12 and the substrate 11. , Compared with the existing light interference type anti-reflection film, it can obtain obviously excellent anti-reflection effect.
[0089] The laminated body 10 of Embodiment 1 can be used for, for example, components of a display device (self-luminou...

[0239] (1) Production of (meth)acrylate copolymer (A) including random copolymer by living radical polymerization
[0240] Metal tellurium (manufactured by Aldrich (Aldrich), product name: Tellurium (-40mesh)) 6.38g (50mmol) was suspended in tetrahydrofuran (THF) 50ml, and n-butyllithium (Aldrich) was slowly dropped thereto at room temperature. Manufactured by the company, 1.6mol / L hexane solution) 34.4ml (55mmol). The dropped reaction solution was stirred until the tellurium metal disappeared completely. To the stirred reaction solution was added 10.7 g (55 mmol) of ethyl-2-bromo-isobutyrate at room temperature, followed by further stirring for 2 hours. After the reaction was over, the solvent was concentrated under reduced pressure, and then distilled under reduced pressure to obtain 8.98 g of ethyl-2-methyl-2-n-butyltellurium-propionate (59.5% yield) of yellow oil ).

[0269](1) Production of (meth)acrylate copolymer (A) including random copolymer by living radical polymerization
[0270] The monomers use the types and usage ratios shown in the above Table 2, adjust the addition amount of ethyl-2-methyl-2-n-butyltellurium-propionate and AIBN, and the polymerization time, in addition to the same as in Example 1 Living radical polymerization was performed on the same conditions to produce solutions of various (meth)acrylate copolymers (A). The properties of each copolymer are shown in Table 2 above.
[0271] (2) Preparation of adhesive composition
[0272] 100 parts by mass (solid content) of each (meth)acrylate copolymer (A) produced by the above (1), each crosslinking agent of the type and amount shown in Table 2 above, 5.0 parts by mass of acetylacetone, and two 0.025 parts by mass of dibutyltin laurate was dissolved in methyl ethyl ketone as a solvent, and solutions of various adhesive compositions having the same solid content concentra...
