The film (6) of a glass laminate (2) is an anti-fogging film obtained by performing a hydrophilic treatment on the surface of a polymer film in which a carbon is substituted in one or more side chains of a glucose ring. The retardation (Ro) in the planar direction of the film (6) is 40-200nm, inclusive. After exposing the film (6) to 40°C steam for 120 seconds under conditions of 55%RH at 23°C and then waiting for 3 seconds, the change in haze in comparison to before the exposure to steam is 3% or less, and the change in retardation (Ro) in comparison thereto is 30% or less. L'invention concerne un film (6) d'un stratifié en verre (2) qui est un film anti-buée obtenu en réalisant un traitement hydrophile sur la surface d'un film polymère dans lequel un carbone est substitué dans une ou plusieurs chaînes latérales d'un cycle de glucose. Le retard (Ro) dans la direction plane du film (6) est de 40 à 200 nm inclus. Après exposition du film (6) à une vapeur à 40 °C pendant 120 secondes dans des conditions de 55 % de HR à 23 °C, puis une attente de 3 secondes, le changement de l'effet de voile par rapport à avant l'exposition à la vapeur est de 3 % ou moins, et le changement relatif du retard (Ro) est de 30 % ou moins.
