Abstract

See full text

Disclosed is a mixture containing compound (I) and polymerizable compound (II) wherein compound (I) accounts for 50 mol % or more of the entire mixture and 1,4-cyclohexanedicarboxylic acid accounts for less than 5 mol % of the entire mixture; a method of producing the mixture which includes reacting in a water-immiscible organic solvent 1,4-cyclohexanedicarboxylic acid dichloride with compound (IV) in the presence of a base, and washing the obtained reaction solution with a weakly acidic buffer solution; etc. The disclosure provides mixtures useful for low-cost production of polymerizable compounds which have low melting points suitable for practical use, show superior solubility to general-purpose solvents, can be produced at low costs, and allow for provision of optical films capable of uniform polarized light conversion over a wide wavelength range, and methods of producing the mixtures.
