PROCESS FOR PRODUCING LAMINATE

摘要

This invention provides a process for producing a laminate, which can simply and stably produce a laminate comprising an optically anisotropic film free from uneven volatilization and uneven coating, having no significant variation in transmittance (not more than 5%) and having a high dichroic ratio (not less than 20). A coating liquid which undergoes a reduction in viscosity with increasing shear rate (thixotropic properties) is provided. When the coating liquid is coated onto a substrate, a high shear rate is applied to the coating liquid to reduce the viscosity of the coating liquid to prevent uneven coating. In this case, since the coating liquid is not excessively diluted to reduce the viscosity, uneven volatilization is less likely to take place. The coating liquid has a concentration in such a range that develops a liquid crystal phase. Accordingly, a lyotropic liquid crystal compound contained in the coating liquid can be aligned by shear stress.
