Abstract

The present invention provides multiple layer interlayers that can be used in multiple layer glass panel type applications to reduce the amount of sound transmitted through the panel while also providing a colored region within a gradient region. The acoustic effect can be achieved by using two or more polymer sheets having differing compositions that have been combined into a single multiple layer interlayer, and the gradient region effect is achieved by forming a colored region in one or more gradient regions of the individual layers.
