WATER-BASE COATING MATERIAL |
摘要 |
Disclosed is an aqueous coating agent comprising a water dispersion (C) prepared by dispersing resin particles containing a water-dispersible polyurethane resin (A) and at least one compound selected from a hydrophobic polyester polyol (B-1) and a hydrophobic polyether polyol (B-2) in water, and a crosslinking agent (D) capable of reacting with a hydroxyl group, wherein the water-dispersible polyurethane resin (A) is obtained by reacting a polyester polyol (a-1), which is obtained by condensing a dicarboxylic acid containing an aromatic dicarboxylic acid as a main component with a polyol, with a polyisocyanate, and also contains 15 to 35% by weight of an aromatic cyclic structural unit, and wherein the hydrophobic polyester polyol (B-1) and/or the hydrophobic polyether polyol (B-2) are liquid at normal temperature and contain 20 to 50% by weight of an aromatic cyclic structural unit.
