A water repellent composition comprising a fluorinated copolymer having structural units based on a monomer (a) having a Cpolyfluoroalkyl group, structural units based on a monomer (b) having a Calkyl group and structural units based on a monomer (c) (halogenated olefin), and a medium, wherein the proportion of the structural units based on the monomer (a) is from 50 to 90 mass % of the structural units (100 mass %) based on all the monomers.

Water repellent composition, its production method, hydrophobic substrate treating agent composition and article

To provide a water repellent composition which is capable of imparting sufficient water repellency and alcohol repellency to a hydrophobic substrate without significantly decreasing the antistatic property imparted to the hydrophobic substrate by an antistatic agent, and which presents a low environmental impact, its production method, a hydrophobic substrate treating agent composition and an article. A water repellent composition having a fluorinated copolymer having structural units based on a monomer (a) having a Cpolyfluoroalkyl group, structural units based on a monomer (b) having a Calkyl group and structural units based on a monomer (c) (halogenated olefin), and a medium, where the proportion of the structural units based on the monomer (a) is from 50 to 90 mass % of the structural units (100 mass %) based on all the monomers.
