To provide a coating composition rapidly forming a cured film exhibiting water- and oil-repellency with a simple process.
The coating agent composition contains (A) at least one kind of fluorine-containing organic silicon compounds expressed by the following formulae (1) or (2): Rf1-QZ1A(1); AZ1Q-Rf2-(Q-Z2-Q-Rf2)x-QZ1A (2) [wherein, Rf1 is a perfluoroalkyl group or a perfluorooxyalkyl group; Rf2 is a perfluorooxyalkylene group; Z1 is a single bond or a 2-9 valent organic group containing 1-15 Si atoms; Z2 is a 2-100Si, divalent polyorganosiloxylene group containing 2-100 Si atoms; Q is a 2-12C, 2-9 valent group, which may contain an oxygen atom and/or a nitrogen atom, but in formula (2) may be each different; is an integer of 1-8; x is an integer of 0-5; and A is a group expressed by the following general formula: -CbH2bSiR3-aXa (wherein, R is a 1-4C alkyl group or a phenyl group; X is a hydrolyzable group; a is 2 or 3; and b is an integer of 0-6)], and (B) a fluorine-containing carboxylic acid having a number-average molecular weight of 100-10,000 and containing 25% by weight, based on the molecular weight, of fluorine atoms, in a ratio of 0.001-10 parts by mass relative to 100 parts by mass of the above (A) component.
