Abstract: An adhesive film includes a single adhesive layer. The single adhesive layer includes an acrylic polymer and an ultraviolet light absorber capable of absorbing in a wavelength range between 320 nanometers and 390 nanometers. The single adhesive layer has first and second opposing major surfaces and a core between the first and second opposing major surfaces. The first and second opposing major surfaces each has an elastic modulus that is higher than an elastic modulus of the core, or the first and second opposing major surfaces each has an elastic modulus that is lower than an elastic modulus of the core. The article can be, for example, an automotive display that includes the adhesive film.
