Description

  The present invention relates to an antiglare hard coat film or sheet for various display devices, and more specifically, a liquid crystal display device, a CRT (cathode ray tube) display device, a plasma display device, an electrochromic display device, a light emitting diode display device, The present invention relates to a hard coat film or sheet suitable for anti-glare for screens of EL (electroluminescence) display devices and various display devices and also having a screen protection function.

In a display such as a liquid crystal display device or a CRT, there has been a drawback that light is incident on the screen from the outside, and this light is reflected on the screen surface to cause glare and the like, thereby making it difficult to view the display image. In particular, with the rapid spread and enlargement of flat panel displays in recent years, solving the above drawbacks (hereinafter referred to as anti-glare) has become an increasingly important issue. In particular, the liquid crystal display itself does not emit light, and unless it has a built-in backlight, it is necessary to perform image display using external light.
Conventionally, as means for imparting antiglare properties, a multilayer vapor deposition film method in which a multilayer vapor deposition layer is provided on the surface of a glass plate, a film, etc., sandblasting, embossing, blending of silica particles (Japanese Examined Patent Publication No. 63-40283), etc. There has been proposed an antiglare layer made of a film, a sheet, or the like whose surface has a fine uneven structure (hereinafter referred to as a fine uneven structure forming method) by various methods.
However, since it is difficult to form a multilayer vapor deposition film on an image display surface having a large area, it is difficult to cope with an increase in the size of the display, and in addition, the cost of forming the multilayer vapor deposition film on the image display surface is difficult. Therefore, there is a drawback that the manufacturing cost of the display is increased.

  On the other hand, in the method of forming a fine concavo-convex structure, as a flat panel display such as a liquid crystal display device becomes thinner and lighter, a transparent plastic film and sheet having a fine concavo-convex surface are directly bonded to the surface of the image display body. Yes. For example, in a polarizing plate used in a liquid crystal display device, a transparent plastic film or sheet is directly bonded to both sides of the polarizing film in order to protect or reinforce the polarizing film. In this case, if a transparent plastic film and sheet having a fine uneven surface are used for the transparent plastic film and the film facing the outside of the sheet, it is not necessary to separately provide an antiglare film and a sheet, thereby achieving a reduction in thickness and weight. The benefits are great. In such a method of use, there is no advantage in reducing the visibility of the original display image, so the hard coat has the performance to maintain the resolution of the display image above a certain level and the surface hardness to prevent the surface from being scratched. Sex is required at the same time.

  However, in the conventional transparent plastic film and sheet having a fine uneven surface, it is difficult to satisfy the resolution of the display image and the hard coat property in a balanced manner. For example, in the method of blending filler particles, if the average particle size is reduced, the resolution is improved, and it is effective to obtain a clear and less glaring display image. If the thickness is not reduced, fine irregularities due to filler particles are not formed on the surface. For this reason, the problem that surface hardness falls arises. In addition, increasing the thickness of the hard coat layer is effective for imparting hard coat properties typified by surface hardness, but the filler particles are buried in the film, so that fine irregularities on the surface are formed. No longer contributes to On the other hand, as a method of forming fine irregularities on the surface in a state where the film thickness is set thick in order to give priority to hard coat properties, [1] a large amount of small particle size filler, [2] a large particle size filler, However, in the case of [1], the film quality of the hard coat layer becomes brittle, and in the case of [2], there arises a problem that the glaring feeling of the display image becomes large. Accordingly, there is a demand for optical properties that have a hard-coating property having a surface hardness that hardly damages the surface of the film or sheet, and a low glare in the displayed image.

  The present invention was made in order to solve the above-described problems required for a film or sheet, and has excellent optical properties and scratch resistance in a well-balanced manner to satisfy an anti-glare property and a clear and clear display image. Another object of the present invention is to provide an antiglare hard coat film or sheet having hard coat properties having surface hardness and chemical resistance.

The first invention of the present invention is an antiglare hard coat film comprising an active energy ray curable resin coating layer on at least one surface of a transparent plastic film or a sheet substrate, wherein the energy ray curable resin coating layer is based on the above.

  As is clear from the description of the above examples, as a feature of the antiglare hard coat film or sheet according to the present invention, it has a mechanical strength imparting function as a protective film on at least one surface of the transparent plastic substrate. After providing the first hard coat layer made of a clear cured resin containing no inorganic or organic fine particles, a thin film of cured resin containing inorganic or organic fine particles was further provided as a second hard coat layer having a light controllability imparting function. The three-layer structure provides optical properties that satisfy a good balance of anti-glare and a clear display image with little glare, and provides hard coat properties with excellent surface hardness and chemical resistance. be able to.

An antiglare hard coat film consisting of three layers of the material and the first and second hard coats was obtained.

<Example 2>
The film thickness of the first hard coat layer on the triacetyl cellulose film (80 μm) is the same as in Example 1 except that the photopolymerization initiator (Darocur 1173) is removed from the first and second hard coat formulations of Example 1. After forming a coating layer of about 5 μm, an electron beam with an acceleration voltage of 200 keV was cured from the coating film side under the condition of an absorbed dose of 2 Mrad, thereby producing a first hard coat layer. Next, after the second hard coat layer is applied on the first hard coat layer cured with the electron beam so as to have a film thickness of about 1.5 μm, an electron beam with an acceleration voltage of 200 keV is applied from the coating side to the absorbed dose of 3 Mrad. The antiglare hard coat film of the present invention was produced by curing under the above conditions.

<Comparative Example 1>
Only one layer of the second hard coat containing filler particles described in Example 1 was formed on the triacetyl cellulose film so as to have a film thickness of 1.5 μm, and then a high-pressure mercury UV lamp (120 W / cm) ultraviolet rays were irradiated under conditions of an integrated light quantity of about 300 mJ / m ² and cured to prepare an antiglare hard coat film having a two-layer structure.

<Comparative example 2>
Only one layer of the second hard coat containing filler particles described in Example 1 was formed on the triacetyl cellulose film so as to have a film thickness of 5.0 μm, and then under the same ultraviolet irradiation conditions as in Comparative Example 1. By carrying out a curing treatment, an antiglare hard coat film having a two-layer structure was produced.

<Comparative Example 3>
The same except that the amount of silica particles (fine seal F80: average agglomerated particle size 1.2 μm to 1.8 μm, manufactured by Tokuyama) containing the filler particles described in Example 1 is 13 parts. By forming an antiglare hard coat layer having a film thickness of 5.0 μm on the triacetylcellulose film in the same manner as in Comparative Example 2 under the composition and ultraviolet irradiation conditions, an antiglare hard coat film having a two-layer structure is formed. Produced.

<Comparative example 4>
Instead of the silica particles of the second hard coat coating composition containing the filler particles described in Example 1 (Fine Seal F80: average aggregated particle size 1.2 μm to 1.8 μm, manufactured by Tokuyama Corporation), a silica having a larger particle size An anti-glare hard coat layer with a film thickness of 6.5 μm was formed under the same composition and ultraviolet irradiation conditions except that particles (Fine Seal P8: average aggregated particle size 5.5 μm to 8.0 μm, manufactured by Tokuyama Corporation) were used. By forming on an acetylcellulose film, an antiglare hard coat film having a two-layer structure was produced.

[Evaluation methods]
About the anti-glare hard coat film obtained from the said Example 1, 2 and Comparative Examples 1-4, various physical properties were measured with the following measuring method, and the result of having evaluated performance is shown in Table 1.
-Haze degree (ratio of light scattered or refracted in parallel light incident on the transparent film):
It measured with the direct reading haze computer (made by Suga Test Instruments).
・ Glittering feeling of display image:
The antiglare hard coat film according to the present invention was brought into close contact with the surface of the LCD display not subjected to the antiglare treatment, and the display image was visually observed and evaluated according to the following criteria.
A +: No glare (very clear)
A: Almost no glare (clear)
B: There is a slight glare feeling C: Large glare feeling (unclear)
·Surface roughness:
The centerline average roughness (Ra) was measured by the surface roughness and contour shape measurement system (Surfcom 550AD, manufactured by Tokyo Seimitsu Co., Ltd.).
・ Coating adhesion:
When 100 pieces of 1 mm × 1 mm crosshatch (mesh) are put on the surface of the cured coating layer by using a cutter, and after attaching cello tape (registered trademark) (manufactured by Nichiban Co., Ltd.), the cello tape (registered trademark) is peeled off. It was evaluated by measuring the number of squares from which the cured coating was peeled off from the film substrate.
·Pencil hardness:
Using pencils with different hardnesses, the presence or absence of scratches under a load of 500 g was determined.
・ Abrasion resistance:
The surface of the hard coat film was rubbed 10 times with a # 0000 steel wool while applying a load of 400 g, the presence or absence of scratches and the extent of the scratches were visually observed and evaluated according to the following criteria.
A: No scratches are observed.
B: Several thin scratches are observed.
C: Countless scratches are observed.

[Evaluation results]
From Table 1, the hard coat films having a three-layer structure shown in Examples 1 and 2 each have a transmission sharpness of 34% to 35%, and are closely adhered to the surface of the LCD display that has not been subjected to the antiglare treatment. As a result, it was possible to observe a clear transmitted character image with clear and less glare. Further, the pencil hardness and scratch resistance were also very good as 3H and A and hard coat properties, respectively.
In Comparative Example 1, both the haze degree and the glare of the display image were almost the same as those of Examples 1 and 2 in terms of optical characteristics, but only the second hard coat layer was formed and the film thickness was thin (1.5 μm). Therefore, the hard coat property was remarkably lowered.
On the other hand, in Comparative Example 2, by increasing the film thickness (5 μm), the hard coat property is improved, and the glare of the display image is remarkably improved, but the haze degree is greatly reduced, and the outline of the indoor fluorescent lamp is the hard coat surface. As a result, the anti-glare effect could not be obtained.
In Comparative Example 3, an attempt was made to add a large amount of silica with a small particle diameter (1.2 μm to 1.8 μm) in order to improve the antiglare effect of Comparative Example 2, but the film quality was low. It became brittle and the hard coat property slightly decreased.
In Comparative Example 4, the hard coat layer is sufficiently thick (6.5 [mu] m) and large particle size silica (5.5 [mu] m to 8.0 [mu] m) is blended to satisfy the antiglare effect and the hard coat property. Although the display image was able to be displayed, the glaring feeling of the display image was large, and a clear transparent character image was observed.
