Problems solved by technology

However, with these known methods of forming asperities, it is difficult to control the uniform formation of asperities
Therefore, rough unevenness may be provided to cause defects in appearance, or when the unevenness is insufficiently formed, anti-blocking performance may be poor

Embodiment 1

[0059] 91 g of pentaerythritol triacrylate (PETA), 3 g of first silica particles (surface treatment: 3-methacryloxypropylmethyldimethoxysilane) with an average particle size of 23 nm, 4 g of average particle size 132nm second silica particles (surface treatment: 3-methacryloxypropylmethyldimethoxysilane), 0.05g fluorine-based acrylate (RS-537, DIC) and 1.95g light The solid component of the initiator (Irgacure 184, Ciba) was diluted to a solid concentration of 45% by weight in a MEK (methyl ethyl ketone) solvent to prepare a composition for the base layer.

[0060] Coat a triacetylcellulose film with this composition using a #10 Mayer rod, dry at 60°C for 1 min, and 2 The dose is irradiated to produce a hard coat film with a thickness of about 5 μm to about 6 μm.

Embodiment 2

[0062]80 g of pentaerythritol triacrylate (PETA), 7 g of first silica particles (surface treatment: 3-methacryloxypropylmethyldimethoxysilane) with an average particle size of 15 nm, 11 g of average particle size 110nm second silica particles (surface treatment: 3-methacryloxypropylmethyldimethoxysilane), 0.1g fluorine-based acrylate (RS-537, DIC) and 1.9g light The solid component of the initiator (Irgacure 184, Ciba) was diluted to a solid concentration of 44% by weight in a MEK (methyl ethyl ketone) solvent to prepare a composition for the base layer.

[0063] A hard coat film was produced in the same manner as in Example 1 using the above composition.

Embodiment 3

[0065] 85 g of pentaerythritol triacrylate (PETA), 4 g of first silica particles (surface treatment: 3-methacryloxypropylmethyldimethoxysilane) with an average particle size of 23 nm, 9 g of average particle size 132nm second silica particles (surface treatment: 3-methacryloxypropylmethyldimethoxysilane), 0.05g fluorine-based acrylate (RS-537, DIC) and 1.95g light The solid component of the initiator (Irgacure 184, Ciba) was diluted to a solid concentration of 44% by weight in a MEK (methyl ethyl ketone) solvent to prepare a composition for the base layer.

[0066] A hard coat film was produced in the same manner as in Example 1 using the above composition.

Abstract

The present invention relates to a hard coating film comprising a substrate layer including: a polymer binder resin; first inorganic particles dispersed in the polymer binder resin and having an average particle diameter of 5 to 70 nm; and second inorganic particles dispersed in the polymer binder resin and having an average particle diameter of 70 to 150 nm, wherein the content of the second inorganic particles having the average particle diameter of 70 to 150 nm is 4 to 12 wt.%, and at least two of the second inorganic particles have a distance between one surface of the substrate layer andthe center of the second inorganic particle of 35 nm to 5.0 um in a direction perpendicular to the one surface of the substrate layer, and are spaced apart from each other by a distance of 0.1 to 1.5um adjacent to each other in a horizontal direction on the one surface of the substrate layer.

Description

technical field [0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2017-0118862 filed on September 15, 2017, the entire contents of which are hereby incorporated by reference in their entirety. [0003] The present invention relates to a hard coat film for the purpose of protecting the surface of a display or the like. Background technique [0004] Image display surfaces in image display devices such as liquid crystal displays, CRT displays, projection displays, plasma displays, electroluminescent displays, etc. need to have scratch resistance to prevent the appearance of scratches during handling. Therefore, the image display surface in an image display device is generally realized by forming a hard coat film on a base film or by using a hard coat film (optical laminate) that additionally has optical functions (for example, anti-reflection properties, anti-glare properties, etc.) ...
