Patent ID: 7763677

Claim:
A water dispersible resin composition comprising 0.01 to 5 parts by mass of a surfactant (C) relative to 100 parts by mass of a combination of 5 to 70% by mass of a side-chain crystalline resin (A) and 95 to 30% by mass of water (B), wherein the side-chain crystalline resin of component (A) is (i) a side-chain crystalline olefin-based polymer obtained by polymerization of one or more of higher α-olefins having 10 or more carbon atoms or (ii) a side-chain crystalline olefin-based polymer obtained by polymerization of one or more of higher α-olefins having 10 or more carbon atoms and one or more of α-olefins having 9 or less carbon atoms and the content of said higher α-olefin unit content is 50 mol % or more and has a melting point of 10-100° C.
