LAMINATED GLASS INTERLAYER AND LAMINATED GLASS

摘要

Objects of the present invention are to provide an interlayer film for laminated glass that includes 2 or more resin layers laminated on each other, exhibits excellent deaerating properties in a manufacturing process of laminated glass, and can prevent the occurrence of ghost images, and to provide laminated glass including the interlayer film for laminated glass. The present invention is an interlayer film for laminated glass that includes 2 or more resin layers laminated on each other. The interlayer film for laminated glass has a large number of recesses and a large number of protrusions on at least one surface thereof. The recesses each have a groove shape with a continuous bottom. The recesses adjacent to each other are parallel to each other and regularly arranged in a line. Within the surface having the large number of recesses and the large number of protrusions, a groove depth (Rzg) of the recesses measured based on JIS B-0601(1994) is 10 µm to 40 µm. Furthermore, a 10-point average roughness (Rz) of a surface of the resin layer having the surface including the large number of recesses and the large number of protrusions measured based on JIS B 0601(1994) is less than 2.7 µm. The 10-point average roughness (Rz) is obtained by peeling off the resin layer having the surface including the large number of recesses and the large number of protrusions from another resin layer coming into direct contact with the aforementioned resin layer and then measuring the surface of the peeled off resin layer on a side of the aforementioned resin layer that came into direct contact with the peeled off resin layer based on JIS B 0601(1994).
