Patent ID: 8734943

Claim:
A resin composition containing, as essential components, a polyester polyurethane polyol (A) prepared by reacting a polybasic acid (E), a polyalcohol (F), and a polyisocyanate (G) as essential components, the polybasic acid (E) being a combination of an aliphatic polybasic acid and an aromatic polybasic acid, the polyisocyanate (G) being a nurate-type polyisocyanate compound having a functionality of 3 or more, the polyester polyurethane polyol (A) having a hydroxyl value of 5 to 30 mg KOH/g, having a branched structure in a molecule thereof, and having a weight average molecular weight (Mw) of 25,000 to 200,000 and a molecular weight distribution (Mw/Mn) of 2.5 or more; a hydroxyl-containing epoxy resin (B) having a number average molecular weight (Mn) of 300 to 5,000; a hydroxyl-containing polycarbonate resin (C) having a number average molecular weight (Mn) of 300 to 3,000; and a polyisocyanate (D).
