PROBLEM TO BE SOLVED: To provide a method for preventing discoloration of a woody building and a woody article and holding their glossiness for a long time.SOLUTION: A coating agent for woody material contains a resin having a structure derived from a bisbenzotriazole phenolic compound represented by the formula (where X is a direct bond, a C1-6 alkylene group, a -O- group, or a -NH- group. Rand Rindependently represent a hydrogen atom, a C1-8 alkyl group, a C1-8 alkoxy group, a C4-12 aromatic group, or a halogen atom, each four of them bound to the ring structure. Rand Rindependently represent a C1-6 alkylene group).SELECTED DRAWING: None 【課題】木質建造物や木質物品において、長期にわたって変色を抑制するとともに光沢を保持するための方法を提供する。【解決手段】（式中、Ｘは、直接結合、炭素数１〜６のアルキレン基、−Ｏ−基、又は、−ＮＨ−基を示す。Ｒ１及びＲ２は独立に、水素原子、炭素数１〜８のアルキル基、炭素数１〜８のアルコキシ基、炭素数４〜１２の芳香族基、又は、ハロゲン原子を示し、環構造にそれぞれ４個結合している。Ｒ３及びＲ４は独立に、炭素数１〜６のアルキレン基を示す。）で表されるビスベンゾトリアゾールフェノール化合物に由来する構造を有する樹脂を含む。【選択図】なし
