“…Epoxy resins with various structures are commercially available, and most of them are based on glycidyl ether structures. However, glycidyl ethers are of concern because of their toxicity to the environment and living organisms [ 7 , 8 , 9 , 10 ], and the development of alternatives is demanded. Other basic skeletons of epoxy resins involve glycidyl esters [ 11 , 12 , 13 ], glycidyl carbamates [ 14 , 15 , 16 ], and alicyclic structures [ 17 , 18 ].…”
