Patent ID: 7491777

Claim:
An aqueous copolymer poly(vinyl ester) dispersion comprising A) 100 parts by weight of a copolymer derived from A1) from 34.9 to 65% by weight of vinyl esters of aliphatic, saturated carboxylic acids, A2) from about 35 to 65% by weight of maleic esters and/or fumaric esters of monohydric aliphatic alcohols having a chain length of C 1 -C 18 and/or alpha-olefins having from 2 to 8 carbon atoms, A3) from 0.1 to 10% of at least one comonomer having at least one stabilizing nonionic or ionic group, and also A4) optionally other comonomers, the sum of components A1), A2), and A3), and optionally A4) giving 100% by weight, based on the total weight of the copolymer, wherein B) from 0.1 to 4.5 parts by weight, based on the total amount of the monomers used, of at least one protecting colloid, C) from 0.1 to 10 parts by weight, based on the total amount of the monomers used, of a nonionic emulsifier, and D) optionally further additives suitable for coating foods.
