Problems solved by technology

[0009] However, the current situation is that in the one-layer type in which a low refractive index layer is laminated only on a hard coat layer, antireflection films having antistatic properties other than siloxane compounds have not been used on the low refractive index layer until now.

Embodiment 1

[0098] (1) Preparation of liquid A (coating liquid for forming a hard coat layer)

[0099] 45 parts by weight of pentaerythritol triacrylate as a trifunctional acrylate monomer [manufactured by Toagosei Co., Ltd., trade name "Aronix M-305", solid content concentration 100%], 0.9 parts by weight of 2 -Methyl-1-[4-(methylthio)phenyl]-2-morpholine-propan-1-one [manufactured by Chiba Specialty Chemicals Co., Ltd., trade name "Irugakuyua 907", solid content concentration 100% ] and 90 parts by weight of a polymer-type cationic antistatic agent having a quaternary ammonium base [manufactured by Colcot, trade name "Colcot NR-121X-9IPA", solid content concentration 9.5% by weight] The mixture was diluted with 1-methoxy-2-propanol to prepare liquid A (coating liquid for forming a hard coat layer) having a solid content concentration of 35% by weight.

[0100] (2) Preparation of liquid B (coating liquid for forming a low refractive index layer)

[0101] 10 parts by weight of pentaeryt...

Embodiment 2

[0108]Except changing the usage amount of antistatic agent " コルコ-ト NR-121X-9IPA " in embodiment 1 (1) to 60 weight parts, carry out in the same way as embodiment 1, prepare antireflection film, the refractive index of hard coat : 1.49

[0109] The physical properties of the thus-prepared antireflection film are shown in Table 1.

Embodiment 3

[0111] Except that the use amount of the MIBK dispersion "ELCOM RT-1002SIV" of porous silica particles in Example 1(2) was changed to 120 parts by weight, the same procedure was carried out as in Example 1 to prepare an antireflection film with a low refractive index Refractive index of layer: 1.40

[0112] The physical properties of the thus-prepared antireflection film are shown in Table 1.

Abstract

A reflection preventive film which comprises a base film and, formed on at least one surface thereof in the following order, (A) a hard coat layer having a thickness of 1 to 20 m and containing a resin cured by the irradiation of an active energy ray and 2 to 25 wt % of an antistatic agent and (B) a low refractive index layer having a thickness of 0.05 to 0.3 m and containing a resin cured by the irradiation of an active energy ray and 30 to 80 wt % of porous silica particles and which has a surface resistivity of 5 X 1012 O / or less. The above reflection preventive film has the characteristic that it has one reflection preventive layer which can effectively prevent the reflection of a light by the surface of an image display element, is excellent in the durability of the antistatic effect for inhibiting the attachment of dust, motes or the like and the resistance to marring and further exhibits excellent resistance to a solvent.

Description

technical field [0001] The present invention relates to an antireflection film, and more specifically, to an antireflection film in which the antireflection layer is a 1-layer type, which can effectively prevent image The light reflection on the surface of the display element, and the durability of the antistatic effect of suppressing the adhesion of dust and dust, etc., are excellent in scratch resistance, and are also excellent in solvent resistance. Background technique [0002] In displays such as PDPs, CRTs, and LCDs, when light is irradiated from the outside to the screen, the light may be reflected and the displayed image cannot be seen. Especially in recent years, with the increase in size of displays, it has become increasingly more important subjects. [0003] In order to solve such problems, various anti-reflection treatments and anti-glare treatments have been performed on various displays so far. As one of these methods, anti-reflection films are used on vario...
