  • Publication number: 20130090403
    Abstract: An exemplary embodiment of the present invention relates to an anti-glare coating composition and anti-glare coating film having excellent abrasion resistance and contamination resistance. The anti-glare coating composition according to the exemplary embodiment of the present invention comprises a) a binder resin; b) a fluorine-based UV curable functional group-containing compound; c) a photoinitiator; d) a surface curable photoinitiator; and e) a particulate of which a surface has an uneven pattern. In the case where a film is formed by using the anti-glare coating composition according to the exemplary embodiment of the present invention, it is possible to provide both abrasion resistance and contamination resistance by a single coating method, to maintain characteristics of abrasion resistance and contamination resistance when the film is rubbed, and to decrease and easily remove contamination by an oil component, such as a fingerprint mark.

  • Publication number: 20120321874
    Abstract: The present invention relates to a coating layer for an anti-glare film that can prevent glaring by reflection of external light on a surface of a display and an anti-glare film comprising the same. The coating layer for an anti-glare film according to an exemplary embodiment of the present invention comprises a binder resin, organic particulates, and inorganic particulates, and differences differences between refractive indexes of the binder resin and the organic particulates and between refractive indexes of the binder resin and inorganic particulates are each 0.3 or less. The coating layer for an anti-glare film according to an exemplary embodiment of the present invention can provide an anti-glare film having excellent anti-glare property, distinctness-of-image, and contrast, such that the coating layer can be applied to a display having high resolution, and has excellent scratch resistance in terms of a coating thickness of a thin film, such that it is easy to enlarge a polarizing plate.

  • Patent number: 8216669
    Abstract: The present invention provides a composition for an anti-glare film that includes a binder resin; and an organic particle which is included in an amount of 1 to 30 parts by weight based on 100 parts by weight of the binder resin and in which concave and convex patterns are formed on a surface thereof, and an anti-glare film that is manufactured by using the same. Accordingly, the storage stability of a particle that is included in an anti-glare film for high resolution is improved to increase the durability and a lifespan of products, a glare phenomenon that is caused by incident light and recognized by an user is prevented, and image clarity and contrast ratio that is realized by using an image display device are improved.
