Embodiment 1
[0107] A 4 mm-thick copper plate having a smooth surface was cut using a diamond engraving knife to prepare a mold. Into the prepared mold, 50 parts by weight of an acrylic monomer (methyl methacrylate: Wako Pure Chemical Industries, Ltd.) and a polyfunctional acrylic monomer (NKェェステル A-TMPT-3EO : Shin Nakamura Chemical Industry Co., Ltd.) 45 parts of the photopolymerization initiator (Irgacure 184: Ciba Seika Japan Co., Ltd.) 5 parts of the mixed solution, covered with a 100 μm thick polyester film (cosmosh ィ ィン A4300: Toyobo Co., Ltd.), roll The resin is evenly stretched so that no air bubbles remain, so that the resin and the polyester film are tightly bonded.
[0108] In this state, irradiate 1500mJ / cm from the side of the polyester film with a metal halide lamp 2 After the UV-curable resin is cured, the polyester film and the resin are peeled off from the mold, the shape of the mold is faithfully transferred, and the anti-Newton ring sheet of Example 1 ( Figure 5 anti-...
Embodiment 2~10
[0110] The anti-Newton ring sheets of Examples 2-10 were produced similarly to Example 1 except having cut|disconnected the copper plate using the cutting conditions different from Example 1. Table 1 shows the structure of the structure row of the anti-Newton ring sheets of Examples 2-10.
