| titleOfInvention | Polarized resin film and process for producing same |
| abstract | An object of the present invention is to provide a polarized vinylidene fluoride/tetrafluoroethylene copolymer resin film that can significantly reduce, when used as an optical film, the deterioration of the quality of video or still images formed by display elements. n The present invention provides a polarized vinylidene fluoride/tetrafluoroethylene copolymer resin film having 2,000 or fewer spot defects per m 2 , the number of spot defects being measured by a defect measurement method; n the method using an surface inspection system in which a CCD camera is placed so as to detect defects at an angle of 45 degrees relative to an LED source, defects of the film are read within a rectangular range of 300 mm in a width direction (the direction perpendicular to the scanning direction), and 150 mm in a machine direction (the scanning direction), while the film is scanned under the camera at a rate of 20 m/min; n wherein first, defects having a bright area of 1.5 mm 2 or less and a dark area of 1.4 mm 2 or less are selected; and n next, in order to remove defects resulting from causes other than a corona treatment contained in these defects, a circumscribed rectangle of defect is set so as to have two sides along the scanning direction, and the number of only defects that have a circumscribed width of 2.88 mm or less, a circumscribed length of 2.3 mm or less, an aspect ratio of −39 to +27, an occupancy area ratio in the circumscribing rectangle of 4,000 to 6,950, and an area ratio of −3,100 to +5,200, is automatically counted as spot defects by the surface inspection system. |
