Abstract: The present invention relates to a film-attached glass substrate, characterized by: being provided with a glass substrate having two primary surfaces each having a compressive stress layer, and a film containing 1 at % or more of K disposed on one of the primary surfaces of the glass substrate; and the ratio of the difference in the amount of K in the compressive stress layer between the primary surfaces, the ratio being represented by formula (1), being −0.027 to 0.027. Formula (1): Ratio of difference in amount of K of compressive stress layer between primary surfaces=(amount of K in first primary surface−amount of K in second primary surface)/[(amount of K in first primary surface+amount of K in second primary surface)/2]

Abstract: To provide an antifouling layer-provided transparent substrate, which is excellent in antiglare and antifouling properties, especially in removability of a creamy product such as hand cream. An antifouling layer-provided transparent substrate, containing a transparent substrate and an antifouling layer provided as the top surface layer on one main surface of the transparent substrate, where the antifouling layer has a divalent group represented by —(OCF2)v(OCF2CF2)w— (where v and w are each independently an integer of at least 1), and the surface of the antifouling layer is such that the mean width RSm of the elements and the arithmetical mean roughness Ra satisfy RSm≥Ra×100+5.

Abstract: A transparent substrate with a light-shielding layer, including: a transparent substrate including a first main surface and a second main surface; an infrared ray-transmitting layer that is disposed so as to be in contact with the first main surface of the transparent substrate, transmits an infrared ray, and shields a visible light; and a light-shielding layer that is disposed on the infrared ray-transmitting layer, includes an opening that exposes a part of the infrared ray-transmitting layer, and shields the visible light and the infrared ray, in which the light-shielding layer includes an end portion that projects from an end portion of the infrared ray-transmitting layer, that is closest to an outer circumference of the transparent substrate, and is in contact with an end face of the infrared ray-transmitting layer and the transparent substrate.

Abstract: A method for evaluating a base material includes deforming a base material. The base material includes a bent portion, and includes a first main surface, a second main surface, and an end surface to change a curvature of the bent portion. The method further includes evaluating a surface state of the first main surface of the base material.

Abstract: There are provided: a composition for forming a water repellent film that can form a water repellent film not only excellent in water repellency but also excellent in abrasion resistance, particularly in abrasion resistance evaluated under close-to-actual-use conditions where a light resistance test is combined; a water repellent film formed by using the composition for forming a water repellent film; a substrate with a water repellent film including the water repellent film provided on at least part of a substrate; and an article including the substrate with a water repellent film. The composition for forming a water repellent film contains, at a predetermined quantitative ratio of a hydrolyzable silane compound (1) having a perfluoroalkyl group and having no ether bond; and a compound (21) that has a poly(oxyfluoroalkylene) group and a plurality of hydrolyzable silyl groups with a specific structure and that has a number average molecular weight of 3000 or more.

Abstract: A cover glass includes a chemically strengthened glass including a first main surface having an area of 12,000 mm2 or larger and a second main surface, and an anti-fingerprint treated layer provided on or above the first main surface. The chemically strengthened glass has a depth of compressive stress layer DOL of 20 μm or larger, has a tensile stress layer having a P2O5 content of 2 mol % or less, and has A×B of 135 or larger, provided that, among oxide components constituting the tensile stress layer, a total concentration of Li2, Na2O, and K2O is A mol % and a concentration of Al2O3 is B mol %. The anti-fingerprint treated layer includes a surface having a frictional electrification amount, as determined by Method D described in JIS L1094:2014, of 0 kV or less and −1.5 kV or more.
