Patent ID: 8889784

Claim:
A stable aqueous dispersion comprising (a) dispersed particles of one or more film-forming polymer, wherein said dispersed particles consist of polymers made from monomers consisting of 10% to 90% by weight vinyl aromatic monomer, 10% to 90% by weight alkyl esters of (meth)acrylic acid and 1% to 10% by weight (meth)acrylic acid, and (b) one or more multiglycidyl compound having 4 or more glycidyl groups per molecule, wherein each of said glycidyl groups is a glycidyl ether group having the structure wherein said aqueous dispersion contains no compound (b) that has any amino groups, wherein said film-forming polymer has glass transition temperature of −25° C. or higher, and wherein said film-forming polymer has glass transition temperature of 35° C. or lower.
