Title:
OPTICALLY TRANSPARENT COMPOSITE FILM FOR DISPLAY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/026005
Kind Code:
A1
Abstract:
The present invention relates to an optically transparent composite film for a display, comprising: a polymer substrate containing a transparent thermoplastic base resin; a plasma surface treatment layer formed on one surface of the polymer substrate and surface-modified through plasma treatment; an inorganic gas barrier layer formed on the upper surface of the plasma surface treatment layer; an organic-inorganic hybrid overcoating layer formed on the upper surface of the inorganic gas barrier layer and including a curable product of a curable sol solution, wherein a curable coating solution in which a (meth)acrylate monomer, an acrylate oligomer containing an epoxy group, which has a weight average molecular weight of 500-10,000, and an initiator are dissolved in a solvent and silica particles are dispersed, is mixed with a sol solution in which a metal alkoxide, a curing accelerator, mineral acid and water are dissolved in a solvent; and an inorganic rear layer formed on the other surface of the polymer substrate, and the optically transparent composite film can improve gas barrier properties such as an excellent moisture blocking property and an oxygen blocking property, and simultaneously improve adhesive force with an inorganic gas barrier layer and the adhesive force of a contact surface coming into contact with a device.
