Abstract:
An aqueous dispersion of polyamide resin, comprising:dispersed polyamide resin particles, basic material and water; wherein the weight average diameter of said dispersed polyamide resin particles is 0.1-10 &mgr;m; the ratio of end carboxyl groups to end amino groups in said polyamide resin ranges from 66/34 to 92/8; the amount of said end carboxyl groups is 90-170 mmol per kg of said polyamide resin; the amount of said basic material added is 0.2-3.0 mol per mol of said end carboxyl groups; and said polyamide resin has as a structural unit at least one selected from the group consisting of â€”[NH(CH2)5CO]â€”, â€”[NH(CH2)6NHCO(CH2)4CO]â€”, â€”[NH(CH2)6NHCO(CH2)8CO]â€”, â€”[NH(CH2)10CO]â€” and â€”[NH(CH2)11CO]â€”.
