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.

The latex polymer compositions of the present invention exhibit latent crosslinking properties. Latent crosslinking in the polymers takes advantage of the fast interaction between the anionic latex charge and the cationic charge associated with 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 improved wash-off properties.

Disclosed are aqueous coating compositions containing an anionically stabilized polymer, one or more polyfunctional amines acting as crosslinking agents, and a volatile base. Coating compositions can further include one or more additional copolymers, which may or may not be anionically stabilized, and/or additional additives, including pigments, defoamers, pigment dispersing agents, thickeners, surfactants, and combinations thereof. By incorporating one or more polyfunctional amines, such as those comprising recurring units derived from the reaction of one tri-glycidyl moiety and a single di-, or tri-functional amino monomer, or a combination of mono/bi, mono/tri, mono/tetra, bi/bi, bi/tri, bi/tetra, tri/tri, tri/tetra, and tetra/tetra functional amino monomers with a bi- or tri-glycidyl moiety, water wash-off resistance of the coating compositions which comprise paint formulations, can be increased.
