Abstract:
A coating film to prevent a conspicuous fingerprint has a water contact angle of no less than 60° so that most of water contained in fingerprints on the coating film evaporates without forming a layer adsorbed on the coating film. Further, the coating film has lipophilicity and has a diiodomethane contact angle of no more than 45° so that the coating film exhibits enhanced affinity to fingerprints, which primarily contain oily components.
