MULTILAYER OPTICAL FILM HAVING HIGH HEAT RESISTANCE, AND METHOD FOR MANUFACTURING SAME |
摘要 |
The present invention relates to a multilayer optical film having a structure in which a first resin layer and a second resin layer are alternately laminated, wherein the first resin layer comprises a crystalline naphthalene dicarboxylic-acid polyester and the second resin layer comprises polyethylene terephthalate glycol (PETG). Further, the present invention relates to a method for manufacturing a multilayer optical film, comprising the steps of: (a) alternately laminating a first resin comprising a crystalline naphthalene dicarboxylic-acid polyester and a second resin comprising PETG having undergone melt extrusion; and (b) stretching the laminated sheet from step (a) and then thermosetting the latter. |
