Retraction of “Synthesis of Monomers Having a 2-Hydroxypyridyl Group and Their Application to Photo-adhesive Materials” [<i>J. Photopolym. Sci. Technol.</i>, <b>36</b> (2023) 267-270]

The authors noticed that structures of monomers 1 and 2 were incorrect after published in J. Photopolym. Sci. Technol., 36 (2023) 267-270. The correct structure of 1 (having a 2-hydroxy or 2-chloropyridyl group) cannot be decided without additional analyses (Fig. 1). On the other hand, the correct structure of 2 is shown in Fig. 2, found after additional MS measurements. Thus, the authors decided to retract the paper. The authors regret any confusion that this issue causes and apologize to the scientific community.
