A long-length film including a plurality of knurl portions shaped by continuous linear concavo-convex portions on at least one surface thereof, wherein the plurality of knurl portions are aligned in a lengthwise direction of the long-length film, a planar shape of the knurl portion seen from a thickness direction of the long-length film includes: 10 or more corners having a curvature radius of 0.3 mm or less and an angle of 100&#xb0; or less or a curvature radius of 0.2 mm or less and an angle of 120&#xb0; or less, per one planar shape of the knurl portion; and 18 or more straight portions having a straight shape, per one planar shape of the knurl portion.

Long film

A method for producing an optical film including a cutting step of performing irradiation with a laser light onto a layered body having a glass support and a resin layer provided on the support to cut the resin layer, wherein in the cutting step, the irradiation with the laser light is performed such that a beam of the laser light has a flat energy distribution, and a distance between a focus of the laser light and a receiving point of the laser light on a surface of the resin layer where the laser light is received or a ratio P/V of an output P of the laser light relative to a scanning speed V is in a specific range.

Method for manufacturing optical film

To allow the correspondence between a region having different susceptibility and a tissue structure to be easily visible, a phase change weighted image is produced by use of a phase of each pixel of phase change image data and a color bar, and an absolute value image is produced by use of an absolute value of each pixel of absolute value image data and a grayscale. Then, a phase change fused image in which the phase change weighted image and absolute value image are overlaid on each other is displayed.
