Abstract:
The present invention provides a method for producing a polymerizable liquid crystal composition which produces films being uncolored and having no cissing and good alignment when applied to a substrate, and also provides a polymerizable liquid crystal composition produced by the method and an optically anisotropic body using the polymerizable liquid crystal composition. Specifically, the present invention provides a method for producing a polymerizable liquid crystal composition, the method comprising a step (I) of preparing a polymerizable solution by mixing at least one polymerizable compound having at least one polymerizable functional group and one or two or more organic solvents and heating and stirring the resultant mixture; and a step (II) of mixing the polymerizable solution with a polymerization initiator, and also provides a polymerizable liquid crystal composition produced by the method and an optically anisotropic body using the polymerizable liquid crystal composition.
