Zusammenfassung:PROBLEM TO BE SOLVED: To provide a primer coating agent formable of a primer layer which is excellent in adhesion to a substrate and a top coat layer, etc., and water resistance such as wet adhesion and water whitening resistance.SOLUTION: The primer coating agent contains: urethane resin (C) having an acid value of 16 to 40 and an aqueous medium (D). The urethane resin (C) is obtained by reacting polyol (A) including polyol (a1) containing aliphatic cyclic structure, polyester polyol (a2) containing aromatic structure, and hydrophilic group-containing polyol (a3) with polyisocyanate (B) including polyisocyanate (b1) containing aliphatic cyclic structure.
