POLYAMIDE RESIN AQUEOUS DISPERSION AND ITS PREPARATION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin aqueous dispersion which is excellent in mixing stability with an acid compound. SOLUTION: The dispersion contains a polyamide resin of which the proportion of a terminal calboxyl group and a terminal amino group is: (terminal calboxyl group)/(terminal amino group)=40/60-0/100 in molar ratio and the acidic material of the proportion of 0.2-3 mol per one mol of the terminal amino group. The number average particle size of particles constituting the dispersion is 0.01-10 μm. COPYRIGHT: (C)2007,JPO&INPIT
