Abstract
A composition comprising (A) a copolymer which comprises (I) repeating units which are derived from a monomer having a fluoroalkyl group, a carbon-carbon double bond, (II) optional repeating units which are derived from a monomer having at least two urethane or urea bonds and a carbon-carbon double bond, but no fluorine atom, (III) optional repeating units which are derived from a monomer, the homopolymer of which having a glass transition temperature (Tg) of 50° C. or less, (IV) optional repeating units which are derived from a monomer having a hydrophilic group and a carbon-carbon double bond, and (V) optional repeating units which are derived from a monomer having a chlorine atom and a carbon-carbon double bond; and (B) a film-forming auxiliary can impart high water and oil repellency by drying at room temperature (0 to 30° C.) without requiring a heat treatment step.
