eng	„Smart“ coating binders based on self-crosslinking acrylic latexes	This study deals with the synthesis of self-crosslinking latexes of microgel core-shell particles by the technique of non-seeded emulsion polymerization. This type of coating binders benefits from the diversity of properties of the resulting latexes. Crosslinking ensuring the microgel structure of latex particles was achieved by adding hexaallylamino-cyclo-triphosphazene, which also ensures to decrease the flammability of the resulting polymer. Like the other monomers, this kind of flame retardant can be incorporated into the structure of microgels by radical copolymerization due to the presence of double bonds in the hexaallylamino-cyclo-triphosphazene molecule. For the interfacial crosslinking, diacetone acrylamide was incorporated in the shell structure of microgel particles to ensure the subsequent crosslinking reaction with adipic acid dihydrazide. Nanoparticles of zinc oxide were added in the polymeric system during the systhesis with the monomers emulsion. Despite adding hexaallylamino-cyclo-triphosphazene and nano- zinc oxide into the polymeric system, the coating transparency was maintained. Moreover, flame stability, mechanical properties and chemical resistance of the prepared coating films were improved. It was shown as well that the coatings exhibited increased flash rust resistance and biocidal effect.	Emulsion polymerisation; Core-shell latex; zinc oxide; Phosphazene; flash rust
