Continuous sheet having optical functions

摘要

A continuous sheet having an optical function imparted thereto, which is obtained by extruding a thermoplastic resin on a three-dimensional pattern side of a continuous release sheet having a three-dimensional pattern in its surface to shus transfer said pattern to a surface of said thermoplastic resin, simultaneously contacting the other side of said thermoplastic resin with a cooling roll having an uneven pattern or a mirror surface to thus transfer said pattern or mirror surface to a surface of said thermoplastic resin in contact with said cooling roll, and separating by peeling said release sheet from said thermoplastic resin after cooling. The continuous sheet is free of a streak and scratch and freely cuttable in any desired size and form.
