摘要： A main chain polymer according to this embodiment comprises, in its polymer main chain, a photoreactive reverse wavelength dispersion unit that exhibits both the functions of photoreactivity and reverse wavelength dispersion of birefringence, wherein the photoreactive reverse wavelength dispersion unit has a structure represented by chemical formula (1) below.

[In chemical formula (1) above, L 1 and L 2 may be the same or different from each other, each representing a carbonyl group, an ester linkage, an amide linkage, an ether linkage or a single bond. * represents a site of binding with another structure in the main chain polymer. Ar represents a ring system selected from the group consisting of a monocyclic aromatic ring system, a polycyclic aromatic ring system and an annulated aromatic ring system whose ring-constituting atoms are atoms selected from the group consisting of a carbon atom, a nitrogen atom, an oxygen atom and a sulfur atom, with the monocyclic aromatic ring system, polycyclic aromatic ring system or annulated aromatic ring system optionally having a substituent. R°, R 1 , R 2 , R 3 and R 4 each independently represent a hydrogen atom, a halogen atom or a C1 to C8 alkyl group.]
