METHOD FOR PRODUCING FILM OR SHEET HAVING THREE-DIMENSIONAL PATTERN ON SURFACE, AND FILM OR SHEET HAVING THREE-DIMENSIONAL PATTERN ON SURFACE |
摘要 |
A method for producing a film or sheet having a three-dimensional pattern for imparting an optical function on the surface thereof, wherein a cycloolefinic resin having a polar group is molten and extruded from a die and then is cast by the use of an end-free metal belt and a metal roll, which comprises transferring the three-dimensional pattern to at least one surface of the film or sheet, by using an end-free metal belt having a three-dimensional pattern formed at least on the surface of a casting face and/or a metal roll having a three-dimensional pattern formed on the surface thereof. The above method allows the production of a film or sheet having a three-dimensional pattern for imparting an optical function on at least one surface thereof, with good accuracy with high productivity with stability. |
