Abstract
An aqueous dispersion of a thermoplastic resin which is capable of forming a coating exhibiting excellent water resistance, oil resistance, chemical resistance and adhesion to non-polar materials as well as its production method and its applications are provided. More particularly, there is provided an aqueous dispersion comprising (A) a thermoplastic resin, (B) a salt of a higher fatty acid, and (C) water, wherein solid content is uniformly dispersed; a method for producing such an aqueous dispersion by melt kneading (A) a thermoplastic resin and (B′) a higher fatty acid and/or an ester thereof, and adding a basic substance and water to the resulting melt kneaded product for neutralization and/or saponification to thereby uniformly disperse of the solid content in the aqueous phase; a thermal transfer ink comprising (A′) an ethylene-vinyl compound copolymer and (B) a salt of a higher fatty acid; and a thermal transfer recording medium having a thermal transfer layer prepared by coating and drying the thermal transfer ink on the substrate.
