Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyacrylate resin which is excellent in heat resistance, color tone and flavor properties and in which generation of a bled material is suppressed.SOLUTION: The polyacrylate resin has a dicarboxylic acid component based on aromatic dicarboxylic acid and/or alicyclic dicarboxylic acid and a dihydric phenol component as constituent components, contains 50 ppm or less free dicarboxylic acid, 30 ppm or less free dihydric phenol, 30 ppm or less cyclic dimer and 1,500 ppm or less linear oligomer having 1,000 or lower molecular weight, and has 100 ppm or less residual solvent and 150°C or higher glass transition temperature. 【課題】耐熱性、色調、フレーバー性に優れ、ブリード物の発生を抑制したポリアリレート樹脂を提供する。【解決手段】芳香族ジカルボン酸及び／又は脂環族ジカルボン酸を主体とするジカルボン酸成分と、二価フェノール成分とを構成成分として得られるポリアリレート樹脂であって、遊離のジカルボン酸が５０ｐｐｍ以下、遊離の二価フェノールが３０ｐｐｍ以下、環状二量体が３０ｐｐｍ以下、分子量１，０００以下の線状オリゴマーが１，５００ｐｐｍ以下含有されており、残留溶剤が１００ｐｐｍ以下であり、ガラス転移温度が１５０℃以上であることを特徴とするポリアリレート樹脂。【選択図】なし
