Abstract
The invention provides a laminated glass and a method of producing the same. This laminated glass includes first and second transparent glass plates and an interlayer film interposed therebetween. This interlayer film has functional ultra-fine particles which have a particle diameter of up to 0.2 .mu.m and are dispersed therein. Due to the incorporation of the ultra-fine particles thereinto, the interlayer film is provided with various additional functions such as heat insulation, ultraviolet ray absorption and the maintenance of a sufficient radio transmittance. Therefore, the laminated glass becomes suitable as an architectural or automotive laminated glass.
