<p>PROBLEM TO BE SOLVED: To provide a cured coating film which has excellent surface characteristics, in particular, excellent scratch resistance and low dynamic friction property in spite of short setting time after coating, by wet coating method.SOLUTION: A surface treatment method for a substrate is provided. A surface-treatment agent includes fluorooxyalkylene group containing polymer composition and/or partial hydrolytic condensate of the fluorooxyalkylene group containing polymer composition. The fluorooxyalkylene group containing polymer composition includes straight-chain fluorooxyalkylene group containing polymer having isopropenoxysilyl group at one terminal and straight-chain fluorooxyalkylene group containing polymer having isopropenoxysilyl group at both terminals (hereinafter referred to as both terminals hydrolytic polymer), in which both terminals hydrolytic polymer has a content of less than 10 mol% (not 0 mol%) with respect to a total molar amount of the straight-chain fluorooxyalkylene group containing polymers. Further, an object whose surface is treated by the surface treatment method is provided.</p> |
