Abstract
A water and oil repellent composition having excellent durability, which can impart excellent water and oil repellency to an object, even in a process at low temperatures, and which enables water and oil repellent treatment providing a soft hand. A water and oil repellent composition which comprises, as an essential component, a copolymer containing polymerization units of the following monomer (a) and polymerization units of the following monomer (b):
- monomer (a): an Rf group-containing monomer which forms a photopolymer having no melting point or a melting point of at most 55° C. attributable to fine crystals derived from the Rf groups and having a glass transition point of at least 20° C.
- monomer (b): a monomer having no Rf group and having a cross-linkable functional group.
