Title:
ポリアミド樹脂水性分散液の製造方法
Document Type and Number:
Japanese Patent JP4404988
Kind Code:
B2
Abstract:
The aqueous dispersion of polyamide resin of the present invention comprises dispersed polyamide resin particles, basic material and water. The dispersed polyamide resin particles have a weight-average diameter of 0.1-10 mu m. The ratio of end carboxyl groups to end amino groups in the polyamide resin is between 60/40 and 100/0. The amount of said basic material added is 0.2-3.0 mol per mol of end carboxyl groups. Such an aqueous dispersion of polyamide resin can be manufactured by adding the polyamide resin to an aqueous dispersion medium containing 0.2-3.0 mol of basic material per mol of end carboxyl groups in the polyamide resin.
