LAMINATED SUBSTRATE FOR WINDOWS, FRAMED LAMINATED SUBSTRATE FOR WINDOWS, VEHICLE COMPRISING LAMINATED SUBSTRATE FOR WINDOWS, AND INTERMEDIATE LAYER STRUCTURE FOR LAMINATED SUBSTRATE FOR WINDOWS

摘要

A laminated substrate for windows, having a plurality of substrates laminated via an intermediate layer structure and having a peripheral edge area along the outer circumference of the laminated substrate for windows in the planar view and a center area on the inside of the peripheral edge area. The intermediate layer structure has a first area and a second area, in the planar view. The second area has an area ratio for the second area relative to the entire area of the laminated substrate for windows, in the planar view, that is at least (-74.87x + 204.47)% when 1.40 ≤ x ≤ 2.72 and at least (-0.0067x + 0.87)% when x 2.72, when x is a value obtained by dividing the second area shear modulus relative to static force by the first area shear modulus relative to static force. The proportion of area occupied by the second area in the center area in the planar view is 0%-83%.
