Title:
COMPOSITION FOR FORMING OPTICAL FILM, OPTICAL FILM AND POLARIZING PLATE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/111054
Kind Code:
A3
Abstract:
The present invention relates to a composition for forming an optical film, an optical film, and a polarizing plate, in which the composition for forming an optical film improves adhesion between an antiglare layer and a light-transmitting base film and enables the antiglare layer and the optical film to exhibit excellent optical characteristics such as appropriate haze, low glossiness, 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 base film, and comprises: a binder-forming compound comprising a multifunctional (meth)acrylate-based compound having three or more functional groups, 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-㎛) scale; and a permeable solvent capable of dissolving at least a part of the light-transmitting base film, wherein the binder-forming compound and the permeable solvent have a weight ratio of 1:0.04 or more.
