A latex composition particularly suited as a paint vehicle for the manufacture of semi-gloss and flat interior paint compositions comprises from 40 to 70% by weight of polymerized resin particles having at least 25% (by weight) vinyl acetate polymerized therein, the particles being substantially spherical and characterized in that not more than 5%of the particles have a diameter greater than 0.65 microns and not more than 5% have a diameter less than 0.33 microns. In the preferred instance, the polymer resin particles comprise vinyl acetate, a lower alkyl acrylate and a conventional wet adhesion monomer, the combination consisting (by weight) of from 80 to 90% vinyl acetate, 10 to 20% of lower alkyl acrylate, e.g., butyl acrylate and 0.2 to 1.5% of wet adhesion monomer.
一种乳胶组合物特别适合用作制造半光和平光内墙涂料组合物的涂料载体,它包括 40% 至 70% (按重量计)的聚合树脂颗粒,其中聚合了至少 25% (按重量计)的醋酸乙烯酯,这些颗粒基本上是球形的,其特征在于不超过 5% 的颗粒直径大于 0.65 微米,不超过 5% 的颗粒直径小于 0.33 微米。在优选情况下,聚合物树脂颗粒由乙酸乙烯酯、低级烷基丙烯酸酯和常规湿粘合单体组成,其组合(按重量计)包括 80% 至 90% 的乙酸乙烯酯、10% 至 20% 的低级烷基丙烯酸酯(如丙烯酸丁酯)和 0.2% 至 1.5% 的湿粘合单体。
