Preparation method of optical film improved engraving efficiency with soft mold by extruding engraving |
| abstract |
The present invention uses an extrusion pulling method in order to maximize production efficiency in producing an optical sheet having a prism pattern tilted by using a soft mold of a belt type comprising a polycarbonate resin and an incompatible material, It is possible to manufacture an optical sheet having excellent porosity and brightness even when releasing at a temperature higher than the glass transition temperature of the glass. |
