Abstract
The present invention provides an antifog-film-attached glass article that includes: a glass base; and an antifog film on a surface of the glass base, wherein the antifog film includes: at least one selected from the group consisting of a silane coupling agent and a cross-linked structure derived from the silane coupling agent; a water-absorbing polymer, a polyether-modified siloxane; and a C2-C8 diol.
Claims20
An antifog-film-attached glass article comprising:
- a glass base;
- and
- an antifog film on a surface of the glass base, wherein
- in a test in which:
- the antifog-film-attached glass article is immersed in water at 25° C. for 24 hours and removed from the water;
- subsequently the antifog film is exposed for 30 seconds to water vapor generated from water at 90° C. to 100° C. disposed at a distance of 60 mm from the antifog film downward in a vertical direction;
- and
- subsequently a judgment is made as to whether information of a QR code disposed at a distance of 110 mm from the antifog film downward in the direction is readable with a camera from an opposite side to a formation side of the antifog film,
- information of a QR code of a 40 mm square size is readable
- where the QR code is a two-dimensional code obtained by encoding, as the information, a character string “Rank:B” under a symbol size of 21×21 modules and a specification of error correction level H, in accordance with Japanese Industrial Standards (JIS)×0510:
- 2018.
