Embodiment 1

[0106] A resin raw material (manufactured by Dainippon Ink Co., Ltd., trade name: GRANDIC PC1071) containing the following ( The raw material which consists of A component, (B) component, (C) component, and the resin component of a photoinitiator. 0.5% by weight of a leveling agent was added to this resin raw material. Then, the resin raw material that has added above-mentioned leveling agent is diluted with ethyl acetate, so that butyl acetate: ethyl acetate (weight ratio)=46: 54 (the ratio of ethyl acetate relative to total solvent is 54% by weight), The solid content concentration was 50% by weight. Thus, the hard coat layer forming material was prepared. The above-mentioned leveling agent is a copolymer of dimethyl siloxane: hydroxypropyl siloxane: 6-isocyanate hexyl isocyanate: aliphatic polyester = 6.3: 1.0: 2.2: 1.0 molar ratio things.

[0107] (A) Component: Urethane acrylate (100 parts by weight) composed of pentaerythritol-based acrylate and hydrogenated xylene d...

Embodiment 2

[0114] In this example, except changing the thickness of the hard-coat layer to 15 micrometers, the same method as Example 1 was carried out, and the hard-coat film was produced.

Embodiment 3

[0116] In this example, except changing the thickness of the hard-coat layer to 25 micrometers, the same method as Example 1 was carried out, and the hard-coat film was produced.

Abstract

A hard-coating layer is formed on at least one surface of a transparent plastic film substrate using a material for forming a hard-coating layer. The material contains Components A, B, and C. Component A is at least one of urethane acrylate and urethane methacrylate. Component B is at least one of polyol acrylate and polyol methacrylate. Component C is a polymer containing a repeating unit represented by General Formula 1 indicated below.

Description

technical field [0001] The invention relates to a hard-coated film, a manufacturing method of the hard-coated film, an optical element and an image display device. Background technique [0002] In recent years, with the advancement of technology, on the basis of the existing CRT (Cathode Ray Tube), liquid crystal displays (LCDs), plasma displays (PDPs) and electroluminescent displays (ELDs) have also been developed and put into practical use. change. Among them, as far as LCD is concerned, along with technological innovations related to high field of view, high definition, high-speed response, color reproduction, etc., applications using LCD are also changing from notebook personal computers or monitors to TVs. . The basic structure of an LCD is that flat glass substrates each equipped with transparent electrodes are arranged to face each other through a spacer so as to form a gap with a certain interval, and a liquid crystal material is injected between the glass substrat...
