Aqueous dispersion, its production method, and its use

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 C4-C20 linear, branched or cyclic diene, and a compound represented by the formula H2C═CHR wherein R is a C1-C20 linear, branched or cyclic alkyl group or a C6-C20 aryl group, wherein the copolymer of propylene is a propylene-rich alpha-olefin interpolymer comprising 5 to 25% by weight of ethylene content and 95 to 75% by weight of propylene content, the copolymer having:
• (a) a melting point of less than 90C;
• (b) a relationship of elasticity to 500% tensile modulus such that the elasticity is less than or equal to 0.935M+12, where elasticity is in percent and M is the 500% tensile modulus in MPa;
• and
• (c) a relationship of flexural modulus to 500% tensile modulus such that flexural modulus is less than or equal to 4.2e0.27M+50, where flexural modulus is in MPa and M is the 500% tensile modulus in MPa.
