ABSTRACT:
The invention relates to a vehicular glass pane having inner and outer major surfaces which are respectively disposed on a first side of a vehicular interior and a second side of a vehicular exterior. The glass pane has a glass plate and a multilayered film formed on one of the inner and outer major surfaces of the glass plate. The glass plate contains a coloring agent. The multilayered film includes a first layer which is light-absorbent and a second layer which is non-light-absorbent. The glass plate and the multilayered film are such that a visible light transmittance of the glass pane is from 25 to 55%, that a first reflectance of the inner major surface of the glass pane is up to 15%, that a second reflectance of the outer major surface of the glass pane is from 10 to 40%, that the visible light transmittance minus the first reflectance is at least 15%, and that the visible light transmittance minus the second reflectance is up to 30%. The glass pane is capable of sufficiently maintaining the vehicular occupants' privacy therethrough and the outward visibility therethrough from the vehicular interior, under various conditions.
