Title:
LAMINATED-GLASS INTERLAYER AND LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2014/077328
Kind Code:
A1
Abstract:
Provided is a laminated-glass interlayer that makes it possible to obtain laminated glass having a gradient pattern with reduced color irregularity. Said laminated-glass interlayer is provided with a dark-color section, a gradient section, and a transparent section. When this laminated-glass interlayer is used in laminated glass using two panes of clear glass, the parallel-light transmittance at points in the dark-color section is less than or equal to 30%, the parallel-light transmittance at points in the gradient section increases continuously from the dark-color-section side to the transparent-section side, and the parallel-light transmittance at points in the transparent section is greater than or equal to 60%. The dark-color section, the gradient section, and the transparent section each have a first resin layer, and the dark-color section and the gradient section each have a second resin layer. Alternatively, the dark-color section, the gradient section, and the transparent section each have a second resin layer, and the gradient section and the transparent section each have a first resin layer. The thickness of the second resin layer in the gradient section decreases continuously from the dark-color-section side to the transparent-section side.
