A polarizing-plate-protecting film is provided, including a polyester film, such as a polyethylene terephthalate film, and an adhesion-facilitating layer formed on one surface of the polyester film, made of a hydrophilic cellulosic resin such as acetyl cellulose. On the other surface of the polyester film, a variety of functional layers, such as a hard coat layer, an anti-glaring layer, and an antireflection layer, are layered.

An object of the present invention is to eliminate drawbacks of conventional multi-layered antireflection films, that is, that a lot of time is required in the formation of a transparent conductive thin film and a low-refractive index layer leading to low processing speed, the corrosion resistance of the transparent conductive thin film is unsatisfactory, and the reflectance over the whole visible light region is not constant. This object can be attained by adopting a structure comprising: a transparent layer, with a pencil hardness of H or more, formed of a cured product of an ionizing radiation-curable resin composition; provided on one side of the transparent layer, a concave-convex portioncomprising innumerable fine concaves and convexes provided at a pitch of not more than the wavelength of light; a transparent substrate filmoptionally provided on the transparent layeron its side remote from the concave-convex portion; and a cover layer, having a lower refractive index than the transparent layer, preferably provided on the fine concaves and convexes.

Process for producing an antireflection film

An antiglare film () comprises: a transparent base film (), a light-diffusing layer () formed on the transparent base film (), and an antiglare layer () formed on the light-diffusing layer (). The antiglare film () has an internal haze value in the range of 35 to 75 and a total haze value in the range of 45 to 85. The light-diffusing layer () and/or the antiglare layer () contains translucent particles coated with a low-refraction coating.

Antiglare film and image display apparatus

An antiglare film has a high level of anti-scintillation properties, high sharpness of transmitted images, high light transmittance (total light transmittance), and a high level of external light reflection preventive properties. A resin and non-agglomerative particles are incorporated in a coating composition using, as a solvent, a good solvent for the resin and a poor solvent for the resin. The coating composition is coated onto a substrate film to form a coating, which is then dried. As the amount of good solvent in the coating decreases, the poor solvent acts to cause gelation of the particles and the resin, allowing concaves and convexes to be advantageously formed on a surface of the resulting antiglare film.

Disclosed are an antiglare film having a high level of anti-scintillation properties, high sharpness of transmitted images, high light transmittance (total light transmittance), and a high level of external light reflection preventive properties, and a process for producing the antiglare film. A resin and non-agglomerative particles having a specific particle diameter are selected so that the difference in refractive index between the resin and the particles is 0.05 to 0.15. The resin and the non-agglomerative particles are brought to a coating composition using, as a solvent, a good solvent for the resin and a poor solvent for the resin. The coating composition is coated onto a substrate film to form a coating which is then dried. In the course of the drying, as the amount of the good solvent in the coating decreases, the poor solvent acts to cause the gelation of the particles and the resin. Thus, good concaves and convexes can be advantageously formed on the surface of the coating. The layer thus formed can meet various property requirements for antiglare films.
