PROTECTIVE FILM

PROBLEM TO BE SOLVED: To provide a protective film which can be stuck to a display device having a display surface having a non-flat surface, a deformable display device and the like so as to follow the shape, is excellent in stability even when having received repeated deformation, is excellent in scratch resistance, and is excellent in antiglare properties and glare prevention properties.SOLUTION: There is provided a protective film 1 formed by laminating a protective layer 30 on a base material 10, where the base material 10 contains a urethane resin or a blend resin of the urethane resin and an acrylic resin, and displacement after a test piece (100 mm×10 mm) has been extended at an extension rate of 400 mm/min by 10%, left at the same time as an extension time, and thereby restored is less than 2%; and a protective film 1 where the protective layer 30 contains a binder resin 32 containing 4-50 wt.% of particles 31 having an average particle size of 2-10 μm and a urethane resin or an acrylic resin or a blend resin of both of the resins. Expression 1 is displacement=(length of test piece during restoration-length of test piece in initial stage)×100/length of test piece in initial stage.SELECTED DRAWING: Figure 1 【課題】表面が平面ではない表示面を持つ表示装置等や変形可能な表示装置等であっても、形状に追従して貼着することが可能であり、繰り返し変形を受けても復元性に優れた、耐擦傷性に優れ、防眩性やギラツキ防止性に優れた保護フィルムの提供。【解決手段】基材１０の上に、保護層３０を積層してなる保護フィルム１であって、基材１０がウレタン系樹脂又はウレタン系樹脂及びアクリル樹脂のブレンド樹脂を含み、試験片（１００ｍｍ×１０ｍｍ）を引張速度４００ｍｍ／ｍｉｎで１０％伸長した後に引張時間と同時間放置することにより復元した後の変位が２％未満である保護フィルム１。保護層３０が平均粒子径２〜１０μｍの粒子３１を４〜５０重量％とウレタン系樹脂或いはアクリル樹脂又は両樹脂のブレンド樹脂を含むバインダー樹脂３２を含む保護フィルム１。変位＝（復元時の試験片の長さ−初期の試験片の長さ）×１００／初期の試験片の長さ（式１）【選択図】図１
