Coating composition, surface treatment agent containing said composition, and article which is surface-treated with said surface treatment agent

According to the present invention, a surface treatment agent which contains a coating composition that contains (A) one or more compounds selected from among organosilane or siloxane compounds represented by formula (1) and partial (hydrolysis) condensation products of the compounds and (B) one or more compounds selected from among silane or siloxane compounds represented by formula (2) and partial (hydrolysis) condensation products of the compounds at a mass ratio of from 50:50 to 90:10 is able to form a cured coating film that has excellently low fingerprint visibility.(In formula (1), A represents -C(═O)OR1, -C(═O)NR12, -C(═O)SR1 or -P(═O)(OR1)2; R1 represents H, an alkyl group, an aryl group or an aralkyl group; Y represents a divalent organic group; R represents an alkyl group or a phenyl group; X represents a hydroxyl group or a hydrolyzable group; and n is 1-3.)(In formula (2), Rf represents a perfluoroalkylene group or a divalent perfluoropolyether group.)
