OIL-BARRIER COMPOSITION

摘要

A water-based oil-barrier composition employing an aqueous medium. The oil-barrier composition is characterized in that it comprises a polymer (A) containing the following monomer units (a<1>), a surfactant (B), and an aqueous medium (C), and that the surfactant (B) comprises at least 50 wt.% fluorochemical surfactant (B<1>) based on the total amount of the surfactant (B). Monomer units (a<1>): monomer units derived from an unsaturated ester containing a polyfluoroalkyl group or monomer units derived from an unsaturated ester containing a polyfluoroalkyl group having an etheric oxygen atom inserted in a carbon-carbon bond.
