WATER-AND-OIL REPELLANT COMPOSITION

摘要

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 R<f> group-containing monomer which forms a photopolymer having no melting point or a melting point of at most 55 DEG C attributable to fine crystals derived from the R<f> groups and having a glass transition point of at least 20 DEG C. monomer (b): a monomer having no R<f> group and having a cross-linkable functional group.
