摘要： The present invention is a liquid-repellent film that exhibits an excellent liquid repellency, and a packaging material of which a surface is formed of the same. The liquid-repellent film comprises: an undercoat part (90) formed unevenly on the substrate surface by microparticles (70) and a thermoplastic resin (80); and a topcoat part (60) having: (i) a minute uneven structured part that includes hydrophilic microparticles (20) having a smaller particle size than the microparticles (70); (ii) a liquid-repellent moiety (40) that bonds to the surface of the minute uneven structured part; and (iii) a binder resin (50) that is present between the surface of the undercoat part (90) and the minute uneven structured part, and is distributed to cover the bonding part of the minute uneven structured part and the liquid-repellent moiety (20).

摘要： A sliding agent includes: a graft polymer obtained by copolymerizing an organic solvent-soluble fluoropolymer having radical polymerizability, a one-terminal radical-polymerizable polysiloxane, and a non-reactive radical-polymerizable methacrylate-based monomer; a one-terminal reactive silicone oil; a hardener; and an organic solvent, and the sliding agent can improve transparency of coating film formed from the sliding agent and durability that can withstand a long-term use, while excellent sliding property of the coating film is maintained.
