An aspect of the present invention defines the composition and the physical properties of a coating solution so that drying unevenness is not caused even when the coated film is dried rapidly based on the premise that the coating solution containing a liquid crystal compound is coated on a flexible strip substrate being transferred in an amount of 4.5 to 12 mL/m

. In the invention, a fluoroaliphatic-group-containing polymer including prescribed repeating units and also satisfying the prescribed condition is added to a coating solution for forming an optically anisotropic layer. As a result, the fluoroaliphatic-group-containing polymer travels rapidly to the interface between the coating solution and air in initial drying after coating, stabilizing the air interface of the coated film. Use of the invention therefore prevents drying unevenness even when the coating amount is increased and the solution is rapidly dried under conditions that tend to cause drying unevenness.

to confirm the structure. The surface activity, biodegradability, antimicrobial, and antifungal activity of the surfactants were evaluated. In addition, quantumchemicalcalculations and computations of oral bioavailability were performed. The obtained data show that all the synthesized compounds had good surface activity, biodegradability and biological activity.
