A light-transmitting electroconductive film (20) according to the present invention includes a region containing krypton at a content ratio of less than 0.1 atomic % at least partially in a thickness direction (D) of the light-transmitting electroconductive film (20). A transparent electroconductive film (X) according to the present invention includes a transparent substrate (10); and the light-transmitting electroconductive film (20) disposed on one surface side in the thickness direction (D) of the transparent substrate.

A transparent electroconductive film (X) includes a resin film (11) and a light-transmitting electroconductive layer (20) in this order in a thickness direction (D). The light-transmitting electroconductive layer (20) has a first compressive residual stress in a first in-plane direction orthogonal to the thickness direction (D), and has a second compressive residual stress less than the first compressive residual stress in a second in-plane direction orthogonal to each of the thickness direction (D) and the first in-plane direction. A ratio of the second compressive residual stress to the first compressive residual stress is 0.82 or less.

The present disclosure addresses the problem of providing an optical plastic film such that rainbow unevenness when viewed with naked eyes and blackout when viewed with polarized sunglasses can be suppressed without any axis alignment or increase in the in-plane phase difference. Disclosed is an optical plastic film satisfying the following conditions 1 and 2: <Condition 1> when a large sample with a size of 200 mm×300 mm is cut out from a plastic film, the large sample is divided into 30 small samples of 40 mm×50 mm, a region of 30 mm×40 mm obtained by excluding 5 mm from each edge of each small sample is subdivided into 47,000 or more regions, and an in-plane phase difference of each subdivided region is then measured, a percentage of small samples in which an average of the in-plane phase difference of each region measured is 50 nm or more and 1,200 nm or less, among the 30 small samples is 50% or more; and <Condition 2> when the 30 small samples are processed in the same manner as in condition 1 and an angle of slow axis of each subdivided region of each small sample is measured, a percentage of small samples in which a standard deviation a calculated from the angle of slow axis of each region measured is 0.8 degrees or more, among the 30 small samples is 50% or more.

A vehicle or other system may have windows. The windows may be formed by laminating together glass layers. The glass layers may include a curved inner glass layer with a convex outer surface and a curved outer glass layer with a concave inner surface. A polymer adhesive film such as a polyvinyl butyral film may be adhered to the convex outer surface. An additional polymer layer formed from a different material than the polymer film may be interposed between the polymer film and the second glass layer. The additional polymer layer may be formed from a gap-filling liquid polymer adhesive layer. The layer of gap-filling liquid polymer adhesive may have a first surface adhered to the polymer film and a second surface adhered to the concave inner surface. An optical layer may be embedded in the additional polymer layer.

A laminated composition shingle includes a first sheet having a first mineral granule surface and a first rectangular shape without tab cut-outs laminated with a second sheet having a second mineral granule surface. The second sheet has tab cut-outs along only one longer edge of the second sheet. The laminated composition shingle has a shingle width and an exposure width perpendicular to the long edges and a first width that is twice the exposure width. The shingle width is the first width plus 2 inches (51 mm). The tab cut-outs have a tab width in the direction of the shingle width less than the exposure width minus ⅛ of an inch (3 mm).

A laminated body for polishing a back surface of a wafer, the laminated body including an intermediate layer that is disposed between a support and a circuit surface of the wafer and peelably adheres to the support and the circuit surface, wherein the intermediate layer includes an adhesion layer in contact with the wafer and a peeling layer in contact with the support, and the peeling layer contains a novolac resin that absorbs light with a wavelength of 190 nm to 600 nm incident through the support, resulting in modification. The light transmittance of the peeling layer at a wavelength range of 190 nm to 600 nm may be 1 to 90%. The modification caused by absorption of light may be photodecomposition of the novolac resin.
