To provide a primer composition excellent in adhesiveness and water resistance.SOLUTION: The primer composition contains: a (meth)acrylic emulsion containing (meth)acrylic particles; and a polymer (A) having a carbodiimide group. The (meth)acrylic particles are particles comprising a predetermined (meth)acrylic polymer (B) obtained by polymerizing a polymerizable monomer (b) having a (meth)acryloyl group. The total content of the (meth)acrylic particles and the polymer (A) is 15 mass% or more and 60 mass% or less based on the total mass of the composition.SELECTED DRAWING: None 【課題】本発明は、接着性および耐水性に優れるプライマー組成物を提供することを課題とする。【解決手段】（メタ）アクリル粒子を含有する（メタ）アクリル系エマルジョンと、カルボジイミド基を有するポリマー（Ａ）を含有するプライマー組成物であって、上記（メタ）アクリル粒子が（メタ）アクリロイル基を有する重合性モノマー（ｂ）を重合させて得られる所定の（メタ）アクリル系ポリマー（Ｂ）からなる粒子であり、上記（メタ）アクリル粒子および上記ポリマー（Ａ）の合計含有量が、組成物の総質量に対して１５質量％以上６０質量％以下である、プライマー組成物。【選択図】なし
