Abstract
This invention provides a water repellant glass plate for vehicles or buildings, which shows a long-term durability. The water repellant glass plate includes a primer layer on a glass substrate, consisting essentially of silicon oxide in which oxygen atoms are partially substituted by hydroxyl groups, at a thickness between 10 nm and 100 nm, and a second layer on the first layer consisting of an organic silicon compound including a fluoroalkyl group at a thickness between about 0.2 nm and about 40 nm.
