Abstract
A polyamideimide resin having isocyanate groups at the terminals, wherein at least a portion of the isocyanate groups are blocked with an ether group-containing cyclic amine.
Claims15
A coating material comprising a polyamideimide resin, a curing agent, and a solvent,
- wherein the polyamideimide resin has isocyanate groups at terminals, and at least a portion of the isocyanate groups are blocked with at least 0.02 mol and not more than 0.15 mol of an ether group-containing cyclic amine per 1 mol of the polyamideimide resin,
- wherein an amount of the curing agent is from 1 to 15 parts by mass, per 100 parts by mass of the polyamideimide resin,
- wherein the solvent consists essentially of the ether group-containing cyclic amine, and
- wherein the polyamideimide resin is produced by reacting one or more diisocyante compounds in the presence of the solvent under conditions that a molar ratio of the solvent to the one or more diisocyanate compounds ranges from 5.62 to 8.94.
