Abstract
A terminal isocyanate group-containing polyamide resin can be produced by reacting a terminal carboxyl group-containing oligomer and a polyisocyanate compound at such a ratio that the amount of an isocyanate group exceeds that of a carboxyl group. An alkoxysilane-modified polyamide resin can be produced by reacting the terminal isocyanate group-containing polyamide resin with an alkoxysilane compound containing a secondary amine.
