Patent ID: 7803865

Claim:
An aqueous dispersion comprising (A) at least one thermoplastic resin; (B) at least one dispersing agent; and (C) water; wherein the dispersion has a pH of less than 12; wherein the thermoplastic resin comprises a copolymer of propylene with at least one comonomer selected from the group consisting of ethylene, a C 4 -C 20 linear, branched or cyclic diene, and a compound represented by the formula H 2 C═CHR wherein R is a C 1 -C 20 linear, branched or cyclic alkyl group or a C 6 -C 20 aryl group, wherein the copolymer of propylene is a propylene-rich alpha-olefin interpolymer comprising units derived from propylene and at least one comonomer selected from the group consisting of ethylene and C4 to C20 alpha-olefins, having a propylene content of greater than 65 mole percent a weight average molecular weight (Mw) of from about 15,000 to about 200,000, a weight average molecular weight/number average molecular weight ratio (Mw/Mn) of from about 1.5 to about 4, and a heat of fusion of from about 30 to about 80 J/g as determined by DSC.
