Provided are an aqueous synthetic resin emulsion, a re-emulsifiable emulsion powder, and an aqueous synthetic resin emulsion obtained by re-emulsifying the re-emulsifiable emulsion powder, the emulsions and the powder being capable of forming a film excellent in water resistance, warm-water resistance, boiling resistance, toughness, and durability. Also provided is an adhesive composition. They are an aqueous synthetic resin emulsion containing a synthetic resin dispersed and stabilized with a polyvinyl alcohol-based resin (a) having a 1,2-diol bond in a side chain thereof, wherein the synthetic resin comprises, as a polymerizable monomer which constitutes the synthetic resin, a hydrophobic monomer having a solubility in water at 20°C of 0.1% or less in an amount of 30% by weight or more based on all polymerizable monomers, the hydrophobic monomers comprising a styrene-based monomer; a re-emulsifiable emulsion powder; and an aqueous synthetic resin emulsion obtained by re-emulsifying the re-emulsifiable emulsion powder.
本发明提供了一种水性合成树脂乳液、一种可再乳化的乳液粉末,以及一种通过再乳化可再乳化的乳液粉末而获得的水性合成树脂乳液,这些乳液和粉末能够形成具有优异的耐水性、耐温水性、耐沸腾性、韧性和耐久性的薄膜。还提供了一种粘合剂组合物。它们是一种水性合成树脂乳液,其中含有分散并用聚乙烯醇基树脂(a)稳定的合成树脂,该树脂的侧链中具有 1,2-二醇键,其中合成树脂包括作为构成合成树脂的可聚合单体的疏水单体,该单体在 20°C 水中的溶解度为 0.1%或更低的疏水单体,其用量为所有可聚合单体重量的 30% 或更多,疏水单体包括苯乙烯基单体;可再乳化乳液粉末;以及通过再乳化可再乳化乳液粉末而获得的水性合成树脂乳液。
