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.
