Problems solved by technology

In this way, on the anti-glare film, although the anti-glare property is obtained by the unevenness of the anti-glare layer, the unevenness of brightness is caused by the unevenness, so it becomes difficult to achieve both excellent anti-glare and suppression of unevenness in brightness.

Embodiment 1

[0112] 〔raw material〕

[0113] The used raw materials are as follows.

[0114] As the photopolymerizable component (A), a photopolymerizable (meth)acryloyl group having a weight-average molecular weight (Mw) of 40,000, which has an acrylic group as its main skeleton and a (meth)acryloyl group as a photopolymerizable functional group on the side chain, was used. ) Acrylic resin (a1) ("ACRIT8KX-078" manufactured by Dacheng Fine Chemical Co., Ltd., solid content 40%).

[0115]As the microparticles (B), alumina microparticle-incorporated silicone microparticles (alumina microparticle-incorporated polyorganosilsesquioxane microparticles: solid content 100%) with an average particle diameter of 1.9 μm were used. In addition, the average particle diameter was measured on the following conditions using a laser diffraction particle diameter distribution measuring device ("SALD-2200" by Shimadzu Corporation).

Description

technical field [0001] The present invention relates to a photocurable resin composition, a cured film and an antiglare film formed from the composition, and a method for producing the cured film and the antiglare film. Background technique [0002] In an image display device represented by a tablet terminal and a television (hereinafter, also simply referred to as a display), the visibility of the screen decreases due to reflection of sunlight or fluorescent lamps on the screen. Therefore, in order to suppress reflection, an antiglare film is provided on the surface of the display. [0003] Generally, an antiglare film is formed by laminating a transparent base material and a cured film having antiglare properties (hereinafter, also simply referred to as an antiglare layer). The anti-glare layer is formed, for example, by applying and curing a photocurable resin composition containing fine particles on a transparent base material, and has fine irregularities generated by t...
