(57) [Summary] [Structure] A fluoroalkyl having an average molecular weight of 500 to 1,000,000 obtained by reacting a raw material component containing a specific difluoroalkanoyl peroxide and a specific silicon-based monomer and / or a specific radically polymerizable monomer. A coating composition comprising a group-containing silicon polymer as an essential polymer component in an amount of 0.01 to 100% by weight based on the entire polymer component. [Effect] Since the coating composition of the present invention contains a fluoroalkyl group-containing silicon polymer as an essential polymer component, it is excellent in water repellency, oil repellency, and stain resistance of the coating film surface. Further, in the fluoroalkyl group-containing silicon polymer, the fluoroalkyl group is introduced by a carbon-carbon bond, so that it is not hydrolyzed, and the aforementioned effects can be maintained for a long period of time, and the adhesion to the coating film can be improved. sex, Excellent coating performance. |
