Problems solved by technology

However, this method requires an additional step of dispersing fine particles with a particle size of 1 nm to 60 nm, and the price of the dispersion liquid is also high when purchased, so the increase in production time and production cost cannot be avoided.

Embodiment 1

[0179] · Translucent substrate

[0180] As a light-transmitting substrate, a polyethylene terephthalate (PET) film (Tetoron KEL86W, Teijin Dupont film Co., Ltd. manufacture).

[0181] · Formation of anti-glare layer

[0182] Using a bar coater, the photocurable resin composition (coating solution) A is coated on the base material so that the average film thickness after drying becomes 4 μm to 5 μm, and then the coating is carried out in an oven at a temperature of 85° C. 2 minutes to dry. Thereafter, using a high-pressure mercury lamp, the irradiation dose was 300mJ / cm 2 Photocuring is performed to form an anti-glare layer.

[0183] It is difficult to measure the refractive index of a layer containing fine particles having a particle diameter exceeding 100 nm by the method described in this specification. Since the resin of the anti-glare layer has a refractive index of 1.52 only at 589 nm, the refractive index of silica fine particles is 1.46, and the refractive index of...

Embodiment 2

[0191] An antiglare layer and an antireflection layer were formed in the same manner as in Example 1, except that the photocurable resin composition (coating liquid) B was used when forming the antiglare layer.

Abstract

The present invention is an anti-glare anti-reflection hard coating film which is capable of providing excellent anti-glare properties and anti-reflection properties, while being suppressed in glare if used in various displays, thereby enabling the achievement of good visibility, and which is also applicable as a film for surface protection. An anti-glare anti-reflection hard coating film according to the present invention is provided with: a substrate 10 in the form of a transparent film; and an anti-glare layer 12 and an anti-reflection layer 11, which are sequentially arranged on one surface of the substrate 10 in this order from the substrate 10 side. The anti-glare layer has a thickness of 3-15 [mu]m; and the anti-reflection layer has a thickness of 50-150 nm. The anti-glare layer isa cured product obtained by curing a resin composition that contains an active energy ray-curable resin; and the resin composition contains silica particles that have a volume average particle diameter of 0.3-0.9 [mu]m.

Description

technical field [0001] The present invention relates to a film having an anti-glare function and an anti-reflection function, and more particularly to an anti-glare anti-reflection hard coating which improves visibility and has hard coating properties by suppressing glare, reflection, reflection, and cloudiness membrane. Background technique [0002] Regarding image display devices (liquid crystal displays, organic electroluminescence (EL) displays, plasma displays, etc.), if indoor lighting (fluorescent lamps, etc.) or external light such as sunlight enters the display surface, due to reflection, reflection, etc. And the visibility is reduced. Therefore, in order to suppress these problems, anti-glare treatment or anti-reflection treatment is performed on the display surface of the image display device. [0003] The anti-glare treatment is a process of providing unevenness on the surface of a layer containing fine particles, and scattering incident light by the unevenness...
