With regard to an optical laminate having a applied film containing a lyotropic liquid crystalline compound, the present invention provides a method of producing an optical laminate that can prevent this applied film from becoming white turbidity.
The present invention is a method of producing an optical laminate having a base material and a applied film laminated on at least one surface of the base material and containing a lyotropic liquid crystalline compound, where the method includes a step A of applying a solution containing at least one kind of a lyotropic liquid crystalline compound on a base material to form a wet applied film, and a step B of drying the wet applied film by spraying a wind onto the surface of the wet applied film simultaneously with this step A or after performing this step A and before the wet applied film is dried. In this step B, the wind is sprayed preferably in a tilted direction, and the wind direction is preferably from 0° to 60° or below relative to the plane of the base material.
关于具有含有亲疏
水液晶化合物的应用膜的光学层压板,本发明提供了一种生产光学层压板的方法,该方法可以防止该应用膜变成白色浑浊。本发明是一种生产光学层压板的方法,该光学层压板具有基材和应用膜,该应用膜层压在基材的至少一个表面上,并且含有亲疏
水液晶化合物,其中该方法包括步骤A,将含有至少一种亲疏
水液晶化合物的溶液涂在基材上以形成湿润的应用膜,以及步骤B,通过在步骤A同时或在执行步骤A之后,在湿润的应用膜表面喷洒风以干燥湿润的应用膜。在步骤B中,最好以倾斜方向喷射风,并且风向相对于基材的平面最好为0°至60°或以下。
