Anti-smudge agent, smudge proof coating composition, smudge proof film, and article coated with smudge proof film

摘要

An anti-smudge agent which is added to a coating composition for imparting smudge proof property with the coating composition, comprising a silicone resin containing a fluorine atom-containing organic group, which has a number average molecular weight of at least 1,000 and a molar ratio of the fluorine atom to the silicon atom (F/Si) of 3 to 50, said silicone resin being produced by hydrolyzing or condensing an organosilicon compound having a fluorine atom-containing organic group represented by the following general formula (I): R1R2mSiX3−m  (I) wherein R1 is a fluorine atom-containing organic substituent, R2 is a substituted or unsubstituted alkyl group or phenyl group containing 1 to 10 carbon atoms, X is a hydrolyzable group or OH group, and m is 0 or 1; or a hydrolysate or a partial condensate thereof.
