Embodiment 1

[0174] 100 parts of urethane acrylate composed of pentaerythritol-based acrylate and hydrogenated xylene diisocyanate are blended as urethane acrylate (hereinafter, component A), and polyol (meth)acrylate (hereinafter, B Components) of dipentaerythritol hexaacrylate (hereinafter, B1 component (monomer)) 49 parts, pentaerythritol triacrylate (hereinafter, B2 component (monomer)) 24 parts, and pentaerythritol tetraacrylate (hereinafter, B3 component (monomer) )) 41 parts, as a (meth)acrylic polymer (hereinafter, C component) having an alkyl group containing two or more hydroxyl groups (meth) having a 2-hydroxyethyl group and a 2,3-dihydroxypropyl group Acrylic polymer (manufactured by Dainippon Ink Chemical Industry Co., Ltd., trade name: PC1097) 59 parts. And then, by the mixed solvent that the mixing ratio of butyl acetate and ethyl acetate is 55:45 (relative to the ethyl acetate ratio of total solvent is 45%), dilute the PMMA particle ( Refractive index: 1.49) 30 parts, reac...

Embodiment 2

[0177] In this example, except that the addition amount of PMMA particles was changed to 15 parts, the same method as in Example 1 was used to produce an anti-glare hard-coat film.

Embodiment 3

[0179] In this embodiment, 30 parts of PMMA particles (refractive index: 1.49) with an average particle diameter of 15 μm are added, and the solid content concentration is changed to 35%. Glare hard coat film.

Abstract

The invention provides a hard-coated antiglare film which includes a transparent film substrate and a hard-coating layer that contains fine particles and is formed on at least one side of the transparent film substrate, wherein the hard-coating layer has a thickness of 15 mum to 30 mum, the fine particles have an average particle size of 30% to 75% of the thickness of the hard-coating layer, and the fine particles form unevenness with a thetaa value of 0.4 DEG to 1.5 DEG according to JIS B 0601. In this way, the invention provides a hard-coated antiglare film with high hardness, high scratch resistance and good antiglare properties, a method of manufacturing the film, an optical element using the film, and an image display including the film or the optical element.

Description

technical field [0001] The present invention relates to an anti-glare hard-coated film in which a hard-coat layer is provided on at least one surface of a transparent film substrate and a method for producing the same. More specifically, it relates to optical elements such as polarizers, image display devices such as CRT (Cathode Ray Tube), liquid crystal display (LCD), plasma display (PDP), and electroluminescence display (ELD). Hard coating film and its manufacturing method. Background technique [0002] There is LCD as one of various image display devices, but along with technological innovations related to LCD's high viewing angle, high definition, high-speed response, color reproducibility, etc., the application of LCD is also changing from notebook type personal Computer or monitor changes to TV. The basic structure of the LCD is that flat glass substrates respectively equipped with transparent electrodes are arranged to face each other through a spacer in a manner o...
