The present invention provides a polymerizable composition containing at least two types of polymerizable compounds represented by Formula (I),

##STR00001## in the formula, A represents a phenylene group or a trans-1,4-cyclohexylene group, L represents OC(O), OC(O)O, and the like, m represents 3 to 12, Sp.sup.1 and Sp.sup.2 represent a linking group, and Q.sup.1 and Q.sup.2 represent a polymerizable group, and the like, in which in a case where a number obtained by dividing the number of trans-1,4-cyclohexylene groups by m is set to mc, mc's for the two types of polymerizable compounds are different from each other, at least one of the two types of the polymerizable compounds satisfies 0.5<mc<0.7, and at least the other of the two types of the polymerizable compounds satisfies 0.5<mc; and a polymerizable compound in which m in Formula (I) is 6 to 12. It is possible to provide a film such as a low birefringence phase difference film or a reflection film having high selectivity in a reflection wavelength range by using the polymerizable composition.

The present disclosure provides monomer compounds that can produce desirable polymeric materials and photo-curable resins. Further provided herein are methods of producing compounds, compositions, resins, devices, and polymeric materials. Also provided herein are methods of using compounds, resins, and polymeric materials for the fabrication (e.g., via 3D printing) of medical devices, such as orthodontic appliances.
