摘要

The method for manufacturing a laminated light control film and manufacturing method, light control film that can have a crack or craze relatively large, it is highly controlled transmission, the optical properties of the scattering or the like, laminated light control film, a light control film be provided. By applying the blade 6a of the drum 6 on the film F, by transferring mechanical film F in the shape of the blade 6a, and a notch is formed in a linear pattern at regular intervals. Notch pattern is formed substantially parallel to the axial direction of the drum 6. By while applying a predetermined tension, is passed through the rolls 8 bending, the addition of the bending stress in the conveying direction of the film F the film F, starting from the notch of the notch pattern, the notch pattern, crack or craze is formed that. Since forming a crack or craze as a starting point the notch pattern, crack or craze large can be obtained relatively, can be highly controlled optical properties.
