PROBLEM TO BE SOLVED: To provide a water dispersed body of polymer particles at least containing polyarylene sulfide, being a dispersed body having high concentration and high stability and capable of reducing baking temperature upon coating film formation.SOLUTION: Composite polymer particles containing polyarylene sulfide and a wholly aromatic linear polymer are coated with an anionic group-containing organic polymer compound by an acid deposition method so as to provide a dispersed body made of the particles, having high concentration and high stability and also capable of reducing baking temperature upon coating film formation. Also provided is powder particles obtainable therefrom.SELECTED DRAWING: None 【課題】少なくともポリアリーレンスルフィドを含有するポリマー粒子の水分散体であって、高濃度で安定性が高く、かつ塗膜形成時の焼付け温度の低温化が可能な分散体を提供することが本発明の課題である。【解決手段】本発明は、酸析法によって、ポリアリーレンスルフィドと全芳香族リニアポリマーを含有する複合ポリマー粒子をアニオン性基含有有機高分子化合物により被覆することで、高濃度で安定性が高く、かつ塗膜形成時の焼付け温度の低温化が可能な該粒子からなる分散体、及びそれから得られる粉体粒子を提供することにより上記課題を解決するものである。【選択図】なし
