<p>PURPOSE:To rapidly and easily produce the direction selective ray adjusting sheet provided with rugged lines for ray adjustment consisting of various kinds of line group patterns on a film base material with good accuracy. CONSTITUTION:The rugged lines 5 for ray adjustment are formed by using a roll intaglio 1 formed with plate recessed parts 6 consisting of shapes for molding these rugged lines, packing an ionizing radiation curing type resin 3 into the plate recessed parts 6 of this roll intaglio 6, bringing the film base material 2 into contact with the intaglio, irradiating the base material with ionizing radiations 7 while the base material maintains contact with the intaglio to cure the resin interposed between the base material and the intaglio and to tightly bond the resin with the base material, then peeling the base material tightly bonded with the cured resin from the intaglio and coloring the rugged lines formed in such a manner.</p> |
