Fluoroalkyl ether, surface modifying composition and method for modifying surface

摘要

A solid surface modifying composition comprising a film forming material and a fluoroalkyl ether ((Rf)m(CONH-X-NHCO-Y)m (m=1 or 2; Rf: perfluoropolyether chain; X: <IMAGE> etc.; <IMAGE> etc.) provides surfaces with such improvements as durable water and oil repellency, lubricity and lowered surface energy. The lubricating protective coating is applicable for coatings of recording mediums, photoreceptors and wirings.
