Paragraph 0510; 0517-0521, (2019/02/28)
A purpose of the present invention is to provide a means by which a polymer can be efficiently manufactured, said polymer being able to be used in the production of an optical film or similar with good reverse wavelength dispersion. In a mixture according to the present invention, the included amount of a polymerizable compound (I) indicated by formula (I) is greater than 0.2 times the included amount of a polymerizable compound (II) indicated by formula (II). (In the formulas, Ar1 and Ar2 are prescribed ring groups; A1-A4 and B1-B4 are cyclic aliphatic groups or aromatic groups and can have a substituent group; Z1-Z4, Y1-Y4, and L1-L4 are prescribed groups such as -O-, -C(=O)-O-, or -O-C(=O)-; R1-R6 are hydrogen atoms, methyl groups, or chlorine atoms; one of e and f is an integer from 1 to 3 and the other is an integer from 0 to 3; c, d, i, and j are integers from 1 to 20; and a, b, g, and h are 0 or 1).
