PROBLEM TO BE SOLVED: To provide a topcoat agent from which a coating film (topcoat layer) having such fingerprint resistance can be formed that even when a fingerprint adheres to the film, the fingerprint gradually becomes less visible with time, thereby an appearance failure is hardly induced, and that a fingerprint can be easily wiped off with a cloth or the like.SOLUTION: The topcoat agent comprises a cationic urethane resin (A) having an alicyclic structure and an aqueous medium (B). The cationic urethane resin (A) includes the alicyclic structure in an amount ranging from 2,000 mmol/kg to 5,500 mmol/kg with respect to the mass of the cationic urethane resin (A). |
