The present invention relates to a glass substrate which is characterized
in that it has a primer layer that is formed thereon and includes a
hydrolysis product of a hydrolysable silicon compound having an alkylene
group and a hydrolysis product of a hydrolysable zirconium compound or
hydrolysable titanium compound, and that, in the primer layer, zirconium
is in an amount by weight ratio of 0.0002 times to 0.0025 times that of
silicon, or titanium is in an amount by weight ratio of 0.0005 times to
0.0045 times that of silicon. Furthermore, the present invention relates
to an anti-fogging article having a resin film that exhibits
water-absorptive property and/or hydrophilic property and is formed on
the primer layer of the glass substrate.
