1000未満の場合には貯蔵安定性が悪いという問題点
がある。The number average molecular weight of the curable resin of the present invention can be used as long as it is 1000 or more, but it is preferably 3000 or more. When the number average molecular weight is less than 1000, there is a problem that storage stability is poor.

うになる。After applying the curable resin of the present invention to the object to be coated, for example, from 80°C to
It is crosslinked and hardened by baking at a temperature of 160° C. for about 30 minutes. Further, by adding a catalyst such as a tertiary amine or a quaternary ammonium salt, it becomes possible to cure the resin at room temperature.
本発明の硬化性樹脂が貯蔵安定性が良好である理由は明
らかではないが、樹脂の分子量の大きいものほど優れて
いる傾向があることから、立体障害による効果であると
考えられる。The reason why the curable resin of the present invention has good storage stability is not clear, but since resins with larger molecular weights tend to have better storage stability, it is thought that this is due to the effect of steric hindrance.
