Abstract

See full text

The present invention relates to a resin composition for forming an optical film, an optical film, and a polarizing plate, in which the resin composition for forming an optical film improves adhesion between an antiglare layer and a light-transmitting substrate film and enables the antiglare layer and the optical film to exhibit excellent optical properties such as appropriate haze, low gloss value, and excellent antiglare properties. The composition for forming an optical film is a resin composition for forming an optical film for forming an infiltration layer and an antiglare layer having surface irregularities on a light-transmitting substrate film, and comprises: a binder-forming compound including a polyfunctional (meth)acrylate-based compound having three or more functionalities, and a permeable compound having a hydrophilic functional group and a photo-curable functional group; two or more light-transmitting fine particles having a sub-micron (sub-μm) scale; and a permeable solvent capable of dissolving at least a part of the light-transmitting substrate film, wherein the binder-forming compound and the permeable solvent have a weight ratio of 1:0.04 or more.
