Abstract
There is provided a novel laminated glass composed partly of plastic sheet advantageous in light weight property, obtainable by the step of laminating a plastic sheet having the first interlayer film adhered to one side thereof and an inorganic glass sheet having the second interlayer film adhered to one side thereof through the first and second interlayer films interposed therebetween, which warps little, exhibits almost no perspective distortion, exhibits satisfactory adhesion between the plastic sheet and the inorganic glass sheet through the interposed interlayer films, and is excellent in transparency.
