Surface treatment composition

Abstract

A composition including a compound containing a carbon-carbon double bond obtained by reacting (A) a polyisocyanate which is a trimer of diisocyanate, with (B) a compound having an active hydrogen, wherein component (B) includes: (B1) a perfluoropolyether having an active hydrogen, (B2) a silane compound having an active hydrogen, and (B3) a monomer having an active hydrogen and a carbon-carbon double bond. Further, a molar amount of an isocyanate group in component (A) is equal to a total molar amount of component (B), and a molar amount of component (B1), component (B2) and component (B3) per 9 moles of the isocyanate group in component (A) are component (B1) 0.1-2 moles, component (B2) 0.05-2 moles, and component (B3) 5-8.85 moles, respectively.
