Abstract:
1. A process for producing a coated sheet, comprising the step of applying a coating solution containing a resin material and a solvent and using a material which makes an optical function onto a substrate film to form a coating layer as an optically functional layer and the step of drying the applied coating solution, wherein dry wind having a wind speed of from 4 to 20 m/sec. and a scattering in the wind speed in the width direction of the film of ±30% or less as well as a temperature of from 20 to 45° C. and a scattering in the temperature in the width direction of the film of ±15% or less dry wind is directly blown along the traveling direction of the film onto the surface of the coating layer wherein the coating solution has a solid content of 55% by weight or less and a viscosity of 20 mPa·s or less.
