ABSTRACT:
An ultraviolet absorbing multilayer coating formed on one side of a transparent substrate includes a first layer formed on a surface of the transparent substrate and a second layer formed on the first layer. The first layer is an ultraviolet absorbing film of a hardened primer coating of a synthetic resin which is mixed with a fluorescent brightening agent and an ultraviolet absorbing agent. The second layer is a film of a siloxane polymer. An optional infrared reflecting coating is interposed between the transparent substrate and the first layer. The ultraviolet rays until the upper limit of its wavelength can be substantially absorbed by the multilayer coating.
