The coating agent comprises a first coating agent comprising an isocyanate group containing an isocyanate group; and a second coating agent comprising (a) a polyol component comprising at least one water-absorbing polyol and a hydrophobic polyol and (b) Surfactants containing groups reactive with isocyanate groups. An anti-fog film may be formed by a method comprising mixing a first and a second coating agent together to prepare a coating agent; coating the coating agent onto a substrate to form a precursor film on the substrate; and The precursor film is hardened into an anti-fog film at room temperature or under heating. Slaves 1. A dual-package coating agent for forming an anti-fog film, the coating agent comprising: a first coating agent comprising an isocyanate component containing an isocyanate group; and a second coating agent, It comprises (a) a polyol component comprising at least one water-absorbing polyol and a hydrophobic polyol and (b) a surfactant comprising groups reactive with isocyanate groups.
