RESIN COMPOSITION, RESIN COMPOSITION SOLUTION, COATING FILM AND COATING

摘要

PROBLEM TO BE SOLVED: To provide a resin composition and a coating film excellent in biological safety and capable of adding water and oil repellency equal to or higher than that of a perfluoroalkyl group-containing (meth)acrylic acid ester polymer material having 6 or 8 carbon atoms to a substrate.SOLUTION: There is provided a curable resin composition containing a polystyrene derivative containing a repeating unit represented by the formula [1] of 1 mass% or more and a thermoplastic resin, the polystyrene derivative of 0.01 mass% or more and 99.0 mass% or less based on the total mass of the polystyrene derivative and the thermoplastic resin and having a contact angle of water of 100° or more or the contact angle of hexadecane of 50° or more, or the contact angle of water of 100° or more and the contact angle of hexadecane of 50° or more of a surface of a coating film formed after applying to a substrate.
