摘要： Polyfunctional amine structures exhibiting at least one hydrophobic moiety selected from the group consisting of; hydrophobic epoxides, hydrophobic glycidyl ethers and hydrophobic (meth)acrylates are described which provide crosslinking capabilities for latex polymer compositions. These crosslinkers not only exhibit latent crosslinking properties but also improved hydrophobicity when compared with existing latex formulations. Latent crosslinking provides advantages associated with fast interactions between the anionic latex charge and the cationic charge associated with these hydrophobically modified polyfunctional amine crosslinkers. Once the latex is coated onto a substrate, the volatile base evaporates and the groups react to form a crosslinked coating with both improved hydrophobic and wash-off properties.
摘要翻译：显示出至少一个选自下组的疏水部分的多官能胺结构：描述了提供胶乳聚合物组合物的交联能力的疏水性环氧化物，疏水性缩水甘油醚和疏水性（甲基）丙烯酸酯。与现有的胶乳制剂相比，这些交联剂不仅具有潜在的交联性能，而且具有改善的疏水性。潜在交联提供了与阴离子胶乳装料与与这些疏水改性的多官能胺交联剂相关的阳离子电荷之间快速相互作用的优点。一旦将胶乳涂覆在基材上，挥发性碱就蒸发掉，并且基团反应形成具有改进的疏水性和洗脱性的交联涂层。
