<p>Provided is a novel protective film which can be easily formed and removed by a simple operation, and which effectively imparts a contamination prevention effect. A protective-film-equipped glass product (1) having a protective film (3) which has a multi-layered structure having: a first film (3a) which is positioned on the surface of a glass product (2) and comprises a cationic surfactant having a hydrophobic group having a carbon number of 8 or higher, or a cationic polymer having an average molecular weight of 5,000,000 to 10,000,000; and a second film (3b) which is positioned on the surface of the first film and comprises an anionic surfactant having a hydrophobic group having a carbon number of 8 or higher, or a nonionic surfactant having a hydrophobic group having a carbon number of 8 or higher.</p> |
