(57) Abstract: An aqueous emulsion of a polyamide resin. An extremely practical aqueous emulsion having low viscosity at room temperature and excellent stability over time is provided. SOLUTION: In an aqueous emulsion of various polyamide resins including a dimer acid-modified polyamide resin, A mixture of emulsifier and C 2 -C 8 diamine and C 2 -C 8 diacids is contained, or emulsifier and C 1 -C 8 to contain an amino acid compound. In addition to the usual emulsifier, a mixture of a specific diamine and a dibasic acid or a specific aminosulfonic acid compound is used in combination, so that a low-viscosity aqueous emulsion of a polyamide resin can be effectively produced, and the dispersion stability over time is excellent. ing. |
