Multiphase polymers comprising crosslinking monomers and polyfunctional amine are disclosed. The multiphase polymer comprises a first phase polymer having a Tg from 60° C. to 240° C., a second phase polymer having a Tg from 40° C. to 240° C., and a soft phase polymer having a Tg from -25° C. to 30° C. The crosslinking monomers include a triacrylate such as trimethylol propane triacrylate, an unsaturated alkoxysilane, and an unsaturated keto monomer reactive with the polyfunctional amine. In contrast to conventional knowledge, incorporation of trimethylolpropane triacrylate reduces the minimum film forming temperature of multiphase polymers. This unusual reduction in MFFT helps to reduce the VOC requirement to form a good film at low VOC. The other crosslinking monomers including unsaturated alkoxy silane and unsaturated keto monomer which react with the polyfunctional amine improve print resistance, block resistance and lower the tackiness of paint films. The multiphase polymer is particularly suitable for use in deep base paints.
