Abstract

The present invention provides an anti-glare hard coat film which has excellent anti-glare properties and can effectively suppress the occurrence of glare even when it is applied to a high-definition display. The present invention is an antiglare hard coat film provided with an antiglare hard coat layer on the surface of a plastic base material. ) component resin particles, a dispersant as (C) component, and a cured product of an anti-glare hard coat layer forming composition as a photopolymerization initiator as (D) component, and the (B) component The volume average particle diameter of the resin fine particles is a value within the range of 1 to 2.5 μm, the added amount of the resin fine particles as the (B) component is a value within the specified range, and the dispersant as the (C) component has a specified limit. As for the compound of a sex group, the addition amount of the dispersing agent which is (C)component is made into the value within a predetermined range.

Description

technical field [0001] The invention relates to an antiglare hard coating film. [0002] In particular, it relates to an anti-glare hard coat film which has excellent anti-glare properties and can effectively suppress the generation of glare even when it is applied to a high-definition display. Background technique [0003] In the past, in displays such as Braun tube (CRT), liquid crystal display (LCD), and plasma display (PDP), the screen reflected incident light from the outside (hereinafter sometimes referred to as "external light"), and it was found that it was difficult to recognize Problems displaying images. [0004] Especially in recent years, with the enlargement of displays, solving these problems has become an increasingly important issue. [0005] Therefore, as one means for solving such external light reflection problems, a technique of using a member having an antiglare hard coat layer has been practiced. [0006] The formation method of this anti-glare hard...
