摘要：
A method of producing a light-scattering film, comprising: disposing a land of a forward end lip of a slot die close to a surface of a web; and applying a coating composition on the web through a slot of the forward end lip, so as to provide the coating composition directly or indirectly on the transparent support, wherein the web is being continuously running while being supported on a backup roll, and wherein the coating composition comprises a light-transmitting particulate material, a transmitting resin and a solvent, and the coating composition satisfies relationship (1) in order to control a sedimentation rate of the light-transmitting particulate material: (σ−ρ)×d2≦1.5 (1) wherein σ represents a density of the light-transmitting particulate material (g/cm2); ρ represents a density of the coating composition (g/cm2); and d represents an average particle diameter of the light-transmitting particulate material (μm).
