Zusammenfassung:	To provide organic fine particles and a water pressure resistance improving composition which are capable of imparting excellent water pressure resistance and waterproofness to a substrate.SOLUTION: Organic fine particles comprise a polymer having a repeating unit formed from (I) a hydrophobic monomer having one ethylenically unsaturated double bond and at least one branched or cyclic hydrocarbon group having 3-40 carbon atoms, and, optionally, (II) a crosslinkable monomer having at least two ethylenically unsaturated double bonds. A water pressure resistance improving composition comprises (A) organic fine particles, and (B) an aqueous medium.SELECTED DRAWING: None 【課題】優れた耐水圧性および防水性を基材に付与できる有機微粒子および耐水圧向上剤組成物を提供する。【解決手段】有機微粒子が、（I）１つのエチレン性不飽和二重結合および少なくとも１つの炭素数３～４０の分岐状または環状の炭化水素基を有する疎水性単量体、および必要により（II）少なくとも２つのエチレン性不飽和二重結合を有する架橋性単量体、から形成される繰り返し単位を有する重合体を含んでなる。耐水圧向上剤組成物が、（Ａ）有機微粒子、および（Ｂ）水性媒体を含んでなる。【選択図】なし
