    • The method of cleaning a coated sheet according to the present invention is characterized in that dry wind is brown along the traveling direction of a film onto the surface of a coating layer wherein the solid content and the viscosity of the coating solution are within specified ranges. By this method, the thickness precision of the coating film can be improved in its large area, and the evenness of its in-plane optically functional property can be made even therein. The speed of the dry wind, the temperature of the wind, and the thickness of the dried coating film are preferably within specified ranges. In particular, the coated sheet is very useful as an optical material having good properties in an optically functional layer which is frequently used as a large-area coated sheet, an optical device having such an optically functional layer, an optically compensating layer, or an optically compensating plate. The coated sheet is particularly effective for an image display on which they are mounted.
    • 根据本发明的清洁涂布纸的方法的特征在于,干燥风沿着涂膜的表面上的膜的行进方向为棕色,其中固体含量和涂布溶液的粘度在规定范围内。 通过这种方法,可以在大面积上提高涂膜的厚度精度,并且甚至可以使其平面内的光学功能性均匀。 干风的速度,风的温度和干燥的涂膜的厚度优选在规定的范围内。 特别地,涂布片材作为光学功能层具有良好性能的光学材料是非常有用的,该功能层经常用作大面积涂布片材,具有这种光学功能层的光学器件,光学补偿层或 光学补偿板。 涂布片对于安装它们的图像显示器是特别有效的。

    • An object of the invention is to provide a process for continuously producing a laminated optical film, the process being able to produce a laminated optical film in which the occurrence of a point defect is suppressed. Provided is a process for producing a laminated optical film, including: a rubbing treatment step of subjecting a surface of a continuous base film to a rubbing treatment to form a rubbing treated surface while the film is transported in a longitudinal direction; a bending transport step of bending and transporting the film subjected to the rubbing treatment step using a plurality of guides for bending the transport direction; and a coating step of coating the rubbing treated surface of the film subjected to the bending transport step with a solution containing a lyotropic liquid crystal compound to form an optically anisotropic film, wherein in the bending transport step, a guide having a gas-jetting device is used as a guide provided on the rubbing treated surface side to bend the transport direction of the film without contacting the rubbing treated surface with the guide.
