Zusammenfassung:	The present invention relates to a composition and a product made by applying the composition to paper. The composition comprises an aqueous dispersion of acrylic or styrene acrylic polymer particles having a hard phase and a soft phase, and the two phases include structural units of specific acid monomers. The composition further comprises Zn^++ or Zr^+++ at substoichiometric levels with respect to a carboxylic acid group. The composition is useful for imparting block and stick resistance as a coating on paper. 본 발명은 조성물 및 상기 조성물을 종이에 도포하여 제조된 물품에 관한 것이다. 상기 조성물은 경질 상 및 연질 상을 갖는 아크릴 또는 스티렌 아크릴 폴리머 입자의 수성 분산물을 포함하며, 상기 두 상은 특이적인 산 모노머의 구조 단위를 포함한다. 상기 조성물은 카복실산기에 대해 아화학량론적 수준의 Zn또는 Zr를 추가로 포함한다. 상기 조성물은 종이 위의 코팅으로서 블록 및 점착 저항성을 부여하는데 유용하다.
