Linear polyfunctional polyglycidyl amine oligomeric and/or polymeric structures exhibiting at least two primary amines are described, which provide crosslinking capabilities for latex paint compositions. These crosslinkers not only exhibit latent crosslinking properties but also improve scrub resistance when compared with existing latex formulations. Once the latex is coated onto a substrate, the volatile base evaporates and the groups react to form a crosslinked coating with improved scrub resistant properties.
