To provide a reactive polymer or the like, having practical level antifogging property continuously, and antifogging property with excellent durability without bleeding out.SOLUTION: There is provided a reactive polymer which is a reaction product of a hydroxyl group-containing hydrophilic polymer (X) and (meth)acryloyl group-containing isocyanate (Y) and has antifogging property, in which the hydroxyl group-containing hydrophilic polymer (X) contains a structural unit derived from hydroxyl group-containing (meth)acrylate (A) and a structural unit derived from a compound represented by the formula (B) and/or a structural unit derived from oxypolyalkylene glycol (meth)acrylate having an oxyalkylene group having average addition mole number of 1 to 10. Rrepresents a hydrogen atom or a methyl group, Rrepresents a single bond, an alkanediyl group, or a *-O-alkanediyl group, and Rand Reach represents a hydrogen atom, a hydroxyl group, an alkyl group or an alkoxy group.SELECTED DRAWING: None 【課題】実用レベルの防曇作用を持続的に有するとともに、ブリードアウトすることなく、耐久性にも優れた防曇性を有する反応性ポリマー等を提供することを目的とする。【解決手段】水酸基含有親水性ポリマー（Ｘ）と、（メタ）アクリロイル基含有イソシアネート（Ｙ）との反応物であり、前記水酸基含有親水性ポリマー（Ｘ）は、水酸基含有（メタ）アクリレート（Ａ）に由来する構造単位と、式（Ｂ）で表される化合物に由来する構造単位及び／又は平均付加モル数１〜１０のオキシアルキレン基を有するオキシポリアルキレングリコール（メタ）アクリレート（Ｃ）に由来する構造単位とを含む防曇性を有する反応性ポリマー。（式中、Ｒ１は、水素原子又はメチル基を表す。Ｒ２は、単結合、アルカンジイル基又は＊−Ｏ−アルカンジイル基を表す。Ｒ３及びＲ４は、それぞれ水素原子、水酸基、アルキル基又はアルコキシ基を表す。）【選択図】なし
