(57) Abstract: Provided is an aqueous emulsion containing fine particles of an allyl-based crosslinked copolymer having good film-forming properties even when diallyl phthalate is substantially completely polymerized. SOLUTION: The diallyl phthalate 10 to 40% by weight, α, β-unsaturated carboxylic acid is 0.1 to less than 5% by weight and the balance is 85% or more of diallyl phthalate obtained by emulsion copolymerization of acrylic acid ester having 1 to 8 carbon atoms of alcohol. An emulsion composition comprising an aqueous emulsion containing allyl-based crosslinked copolymer fine particles having an average particle diameter of 200 nm or less and a crosslinking agent. |
