The feasibility of making crosslinkable latexes by emulsion polymerization in the presence of etherified melamine-formaldhyde (MF) resins was demonstrated. In favorable cases the resulting latexes crosslinked at ambient temperatures to give tough, solvent-resistant films. High levels of acid catalyst are required. A monomeric, hydrophobic MF resin etherified with about five moles of methanol and one mole of isooctanol gave better overall results than monomeric MF resins etherified entirely with methanol, which are more hydrophilic, or with polymeric MF resins etherified with butanol, which are less miscible in acrylic copolymers with compositions similar to the crosslinkable latex.
