PROBLEM TO BE SOLVED: To provide a coating composition containing no harmful bisphenolic substance as food or coating which comes in contact with food on a container for beverage.SOLUTION: A powder coating composition contains a polyether polymer containing one or more segments represented by formula (I). In formula (I), R1 each independently represents an atom or a group having an atomic weight of at least 15 Dalton; v each independently represents an integer of 1-4; w represents 4; each phenylene group contains at least one R1 bonded to a ring of shown O in ortho- or meta-position; R2 represents a divalent group, if present; n represents 0 or 1; but when n is 0, the phenylene group is bonded, as needed, to form a condensed ring system, and W represents 3; and two or more R1 and/or R2 are bonded to each other to form one or more cyclic groups.SELECTED DRAWING: None 【課題】食品又は飲料用容器上の食品に接触するコーティングとして、有害なビスフェノール系物質を含まないコーティング組成物を提供。【解決手段】式（Ｉ）で示される１つ以上のセグメントを含有するポリエーテルポリマーを含む、粉末コーティング組成物。（Ｒ１は各々独立に、少なくとも１５ダルトンの原子量を有する原子又は基；ｖは各々独立に１〜４の整数；ｗは４；フェニレン基の夫々は、示されたＯに対してオルト又はメタ位で環に結合する、少なくとも１つのＲ１を含有；Ｒ２は、存在する場合、二価の基；ｎは０又は１；但し、ｎが０である場合、フェニレン基は、必要に応じて結合して、縮合環系を形成することができ、ｗは３；２つ以上のＲ１及び／又はＲ２は結合して、１つ以上の環式基を形成）【選択図】なし
