PROBLEM TO BE SOLVED: To provide emulsion which is excellent in resin physical properties, coating film formability, adhesion to a base material, flexibility, heat resistance, and chemical resistance, and is further excellent in sanitary properties, discarding properties and recyclability.SOLUTION: Emulsion contains a polyester-based thermoplastic elastomer in liquid as a solid content. An average particle diameter of the solid content is 0.05-1.0 μm, and a concentration of the solid content is preferably 20-45 mass%, and a polybutylene terephthalate-polyalkylene glycol block copolymer modified with an unsaturated carboxylic acid (anhydride) is preferable as the polyester-based thermoplastic elastomer.SELECTED DRAWING: None 【課題】樹脂物性、塗膜形成性に優れ、基材密着性、柔軟性、耐熱性、耐薬品性、更には衛生性、廃棄性、リサイクル性に優れたエマルジョンを提供する。【解決手段】液中にポリエステル系熱可塑性エラストマーを固形分として含むエマルジョン。固形分の平均粒径は０．０５〜１．０μｍで、固形分濃度は２０〜４５質量％が好ましく、ポリエステル系熱可塑性エラストマーとしては、不飽和カルボン酸（無水物）により変性されたポリブチレンテレフタレート−ポリアルキレングリコールブロック共重合体が好ましい。【選択図】なし
