PROBLEM TO BE SOLVED: To provide a composition for antifouling coating good in storage stability of coating, excellent in dryness property of the coating by capillarity phenomenon between polymer particles and useful for a hybrid type antifouling coating.SOLUTION: There is provided a composition for antifouling coating containing a metal-containing polymer particle, an organic solvent and an acrylic polymer soluble in the organic solvent (P). There is provided a metal-containing polymer particle obtained by polymerizing an ethylenic unsaturated monomer mixture (M) containing a bi- or higher valent metal-containing ethylenic unsaturated monomer (a1) of 8 to 65 mass%, a carboxyl group-containing ethylenic unsaturated monomer (a2) of 0.5 to 8 mass% and other ethylenic unsaturated monomers (a3) of 27 to 91.5 mass%.SELECTED DRAWING: None 【課題】塗料の貯蔵安定性が良く、重合体粒子間の毛細管現象により塗膜の乾燥性に優れたハイソリッド型の防汚塗料に有用な防汚塗料用組成物を提供する。【解決手段】金属含有重合体粒子と、有機溶剤と、前記有機溶剤に可溶なアクリル系重合体（Ｐ）とを含む防汚塗料用組成物。２価以上の金属含有エチレン性不飽和単量体（ａ１）８〜６５質量％と、カルボキシル基含有エチレン性不飽和単量体（ａ２）０．５〜８質量％と、その他のエチレン性不飽和単量体（ａ３）２７〜９１．５質量％とを含むエチレン性不飽和単量体混合物（Ｍ）を重合して得られた金属含有重合体粒子。【選択図】なし
