Patent ID: 8207253

Claim:
An aqueous adhesive composition comprising: A) a polymer selected from the group consisting of polyvinyl acetate, copolymers of vinyl acetate with at least one member selected from the group consisting of ethylene, esters of acrylic and methacrylic acids, and polyurethanes; B) from 1 to 50 weight percent, based on the weight of said polymer, of a plasticizer composition comprising 1) a mixed diester corresponding to formula (I) R 1 C(O)OR 2 O(O)CR 3 ; 2) from 20 to 100 weight percent, based on the weight of said mixed diester, of a diester corresponding to formula (II) R 1 C(O)OR 2 O(O)CR 1 ; 3) from 0 to 40 weight percent, based on the weight of said mixed diester, of an ester corresponding to formula (III) R 3 C(O)OR 2 O(O)CR 3 ; and a total of from 0 to 30 weight percent, based on the total weight of said ester composition, of at least one monoester corresponding to at least one formula selected from the group consisting of R 1 C(O)OR 2 O(O)H and R 3 C(O)OR 2 O(O)H; and an aqueous solvent; wherein R 1 is at least one radical selected from the group consisting of phenyl, alkyl-substituted phenyl, and mixtures thereof, R 2 is at least one divalent radical of a formula selected from the group consisting of R 4 , —R 5 (OR 5 ) m — and mixtures thereof, R 3 is at least one member selected from the group consisting of hydrogen and alkyl radicals containing from 1 to 2 carbon atoms, R 4 is selected from the group consisting of linear and branched alkyl radical containing from 3 to 12 carbon atoms, R 5 is an alkylene radical containing from 2 to 6 carbon atoms, m represents at least one of the integers 1 and 2 and the molar ratio of R 1 to R 3 radicals is from 1:12 to 12:1.
