(METH) ACRYLIC RESIN EMULSION FOR PAPER COATING, AND FILM AND LAMINATE

To provide a (meth) acrylic resin emulsion for paper coating capable of forming a film excellent in water resistance and blocking resistance even when dried under a low temperature, and a film and a laminate thereof.SOLUTION: A (meth) acrylic resin emulsion for paper coating contains: particles of a resin which has a structural unit (A) derived from a (meth) acrylic monomer having carboxy group and a structural unit (B) derived from a reactive surfactant having ethylenically unsaturated double bond, the content of the structural unit (A) being between 0.1 mass% or more and 10 mass% or less based on the total mass of structural units (except the structural unit (B)) and the content of the structural unit (B) being between 0.5 mass% or more and 10 mass% or less based on the total mass of structural units (except the structural unit (B)), and has a glass-transition temperature between 0°C or more and 40°C or less and an average particle diameter between 30 nm or more and 200 nm or less; and an aqueous medium. Further, there is provided the application of the (meth) acrylic resin emulsion for paper coating.SELECTED DRAWING: None 【課題】低温で乾燥した場合においても、耐水性と耐ブロッキング性とに優れる膜を形成できる紙コーティング用（メタ）アクリル樹脂エマルション、膜、及び積層体を提供する。【解決手段】カルボキシ基を有する（メタ）アクリル単量体に由来する構成単位（Ａ）及びエチレン性不飽和二重結合を有する反応性界面活性剤に由来する構成単位（Ｂ）を有し、前記構成単位（Ａ）の含有率が、構成単位（但し、前記構成単位（Ｂ）を除く。）の合計質量に対して０．１質量％以上１０質量％以下であり、前記構成単位（Ｂ）の含有率が、構成単位（但し、前記構成単位（Ｂ）を除く。）の合計質量に対して０．５質量％以上１０質量％以下であり、ガラス転移温度が０℃以上４０℃以下であり、かつ、平均粒子径が３０ｎｍ以上２００ｎｍ以下である樹脂の粒子と、水性媒体と、を含む紙コーティング用（メタ）アクリル樹脂エマルション、並びにその応用。【選択図】なし
