Abstract: The present invention addresses the problem of providing: a laminated body which includes a polyolefin resin substrate, is dense, and has good barrier properties; a packaging body; and a method for producing the laminated body. The solution to this problem is a laminated body comprising a polyolefin resin film, a metal layer and/or an inorganic compound layer, and a coating layer being disposed in this order on at least one surface of the polyolefin resin film. The ratio P1/P2 between peak intensities P1 and P2 is 3.5-8.0, the peak intensities being determined by measurement with a FT-IR-ATR method. P1 is the intensity of the greatest peak present in the 1,050 to 1,080 cm?1 range; and P2 is the intensity of the greatest peak present in the 920 to 970 cm?1 range.

Abstract: An antireflection member comprising an antireflection layer includes two adjacent layers with different refractive indices, the antireflection layer formed at least on a first surface of a support substrate, and one of the two adjacent layers with different refractive indices located farther from the support substrate is a first layer, and another of the two adjacent layers is a second layer, wherein the antireflection layer contains two or more kinds of particles of different constituent elements and one or more kinds of binders, and a ratio b/a is more than 1.10 and less than 1.

Abstract: A laminated body is a laminated body that has in this order a second layer and a first layer with different indices of refraction on at least one surface of a supporting base material, and the first layer contains particles X (particles X being particles having at least an inorganic particle part), with the second layer containing particles Y (particles Y being particles having at least an inorganic particle part) and is characterized by the number average particle size (DX in the following) for the inorganic particle parts for the particles X being 5-25 nm and by Equations 1 and 2 being satisfied: 1.4?(LX/DX)?3??1 SLX?7??2.
