A hard-coated antiglare film is provided that has high hardness, high scratch resistance, and good antiglare properties. In the hard-coated antiglare film of the present invention including a transparent plastic film substrate, a hard-coating layer containing fine particles is formed on at least one surface of the transparent plastic film substrate, the hard-coating layer has a thickness in the range of 15 to 30 &#x3bc;m, the fine particles have a weight average particle size of 30 to 75% of a thickness of the hard-coating layer, the average tilt angle &#x3b8;a of the unevenness of the hard-coating layer surface is in the range of 0.4&#xb0; to 1.5&#xb0;, and the hard-coating layer is formed using a resin for forming the hard-coating layer containing three specific resin components.

Hard-coated antiglare film, method of manufacturing the same, optical device, polarizing plate, and image display

There is provided an antiglare hard-coated film that can maintain antiglare properties and suppress a reduction in the display contrast of a display, when composed of a transparent plastic film substrate and an antiglare hard coat layer formed thereon. The antiglare hard-coated filmincludes a transparent film substrateand a hard coat layerthat is provided on at least one side of the transparent film substrate, contains fine particles, and has an irregular surface, wherein the fine particleshave an average particle size of 6 &#x3bc;m to 15 &#x3bc;m and form irregularities with an average slope angle &#x3b8;a of 0.4&#xb0; to 1.5&#xb0;, and the antiglare hard-coated film satisfies the relation: {(the contrast ratio)/(the contrast ratio of a hard-coated film without the fine particles)}&#xd7;100&#x2267;60%.

Antiglare hard-coated film

There are provided 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. The hard-coated antiglare film of the invention 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 &#x3bc;m to 30 &#x3bc;m, 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 &#x3b8;a value of 0.4&#xb0; to 1.5&#xb0; according to JIS B 0601.
