摘要：
A method for producing a light-scattering film that comprises a light-scattering layer on a transparent support, comprising: 1) a step of preparing a coating composition for the light-scattering layer, which comprises: translucent particles; a translucent resin that comprises a translucent polymer having a molecular weight of 1000 or more in a ratio of 0.1% by mass or more of the coating composition; and a solvent, 2) a step of running the transparent support which is supported by a backup roll, 3) a step of jetting out the coating composition for the light-scattering layer through a tip of a slot die of an extrusion-type coating machine; and 4) a step of applying the coating composition for the light-scattering layer that has been jetted out through a slot of a tip lip of the slot die, onto the transparent support, while a land of the tip lip is kept adjacent to a surface of a web of the running transparent support.
