Zusammenfassung:	To provide a composition for imparting block and tack resistance as a coating on paper.SOLUTION: A composition comprises an aqueous dispersion of polymer particles having an average particle size in the range of 80 nm to 500 nm; wherein the polymer particles comprise a first phase having a Tg of greater than 50°C and a second phase having a Tg of less than 35°C; wherein the weight-to-weight ratio of the first phase to the second phase is in the range of from 5:95 to 50:50. Both phases of acrylic or styrene acrylic polymer particles, as the polymer particles, having a hard phase and a soft phase, comprise structural units of a specific acid monomer. The composition further includes sub-stoichiometric levels of Znor Zrwith respect to the carboxylic acid groups.SELECTED DRAWING: None 【課題】紙へのコーティングとして、耐ブロッキング性及び耐粘着性を付与する組成物の提供。【解決手段】８０ｎｍ〜５００ｎｍの範囲の平均粒径を有するポリマー粒子の水性分散液を含む組成物であって、前記ポリマー粒子が、５０℃超のＴｇを有する第１の相と、３５℃未満のＴｇを有する第２の相とを含み、前記第１の相の前記第２の相に対する重量対重量比が、５：９５〜５０：５０の範囲内である。前記ポリマー粒子である、硬質相及び軟質相を有するアクリルまたはスチレンアクリルポリマー粒子の両方の相が、特定の酸モノマーの構造単位を含む。本組成物は、カルボン酸基に対して準化学量論レベルのＺｎ＋＋またはＺｒ＋＋＋＋を更に含む。【選択図】なし
