Embodiment 1
[0017] As the protective film made of a resin material, #9070 (thickness: 60 μm) produced by NOVACEL Ltd. was used. For the protective film, according to Method A in JIS K7210:1999, using a melt indexer (L207 produced by Takara Kogyo Co., Ltd.) under a load of 2.16 kg, measured at a cylinder temperature of 190° C. The amount of molten resin material flowed out in 10 minutes, and its value is shown in Table 1 in the form of MFI (g / 10 minutes).
[0018] Both sides of an acrylic resin plate having a thickness of 5 mm were laminated using the above-mentioned protective film made of a resin material to obtain an acrylic resin plate provided with a protective film. The acrylic resin plate provided with the protective film was heated to 200°C, and then a sample with a width of 25 mm was cut out from the resin plate at room temperature, and passed the 180° peel test method according to JIS K6854-2:1999, using an automatic The plotter measured the average peeling force (N) of this sam...
Embodiment 2
[0021] The same procedure as in Example 1 was carried out except that #9006 (thickness 79 μm) produced by NOVACEL Ltd. was used as the protective film made of a resin material. The results are shown in Table 1.
