Embodiments of the present invention enable accurate climate forecasting without the need to run new dynamical global climate simulations on supercomputers. Also disclosed are benefits of the new methods, and alternative embodiments of implementation. | 2020-11-05 |
20200348449 | ANTI-GLARE HARD COAT LAMINATED FILM - One embodiment provides a hard coat laminated film, comprising, in order from a surface layer side, a first hard coat, a second hard coat, and a transparent resin film layer, where the first hard coat is formed of a coating material including: (A) 100 parts by mass of a polyfunctional (meth)acrylate; (B) 0.01 to 7 parts by mass of a water repellent; (C) 0.01 to 10 parts by mass of a silane coupling agent; and (D) 0.1 to 10 parts by mass of resin microparticles having an average particle diameter of 0.5 to 10 μm, and containing no inorganic particles, and where the second hard coat is formed of a coating material containing inorganic particles. Another embodiment provides a hard coat laminated film having, in order from a surface layer side, a first hard coat, a second hard coat, and a resin film layer. The first hard coat includes a coating material that does not include inorganic particles. The second hard coat includes a coating material including inorganic particles. The adhesive film fulfills the conditions: (i) a total light transmission rate of at least 85%; (ii) a pencil hardness for the first hard coat surface of at least 5H; and (iii) a Y value for an XYZ color system of 1.5%-4.2%. | 2020-11-05 |
